Eiko Koike Beauty & Wellness | Skincare, Diet, Fitness & Sleep

OBARASOTARO

From her powerful performances in films, television dramas and theatre to her warm, candid personality on variety shows, Eiko Koike is a Japanese actress admired for both her versatility and down-to-earth charm. Now in her 40s, she continues to grow as a performer. But what beauty routines and wellness habits are part of her everyday life?

Her approach to beauty is surprisingly natural and practical. She has long valued the cleansing advice passed down by her grandmother, and later introduced morning and evening sheet masks after receiving skincare tips from fellow entertainer MEGUMI. Rather than following a rigid routine, Koike has enjoyed discovering habits that suit her changing lifestyle.

Her food preferences are equally distinctive: two rice balls for breakfast, firm-textured rice shared with her husband, hearty miso soup, mushroom dishes, kombucha and manuka honey. She has also spoken about fitness training for acting roles, prioritising eight hours of sleep, enjoying a bath even in summer, listening to music before bed and walking her beloved dogs.

Drawing primarily on interviews with Koike herself, this article explores Eiko Koike's beauty routine, skincare habits, diet, fitness, sleep and ways of relaxing. Along the way, we look at her most notable acting roles, marriage, family life and entertaining childhood stories to discover the person behind the performances.

1. Eiko Koike's Career, Marriage and Changing Views on Beauty

From Gravure Idol to Acclaimed Actress: Notable Roles and Life with Husband Wataru Sakata

Eiko Koike was born on 20 November 1980 in Tokyo, Japan. She entered the entertainment industry in 1998, initially attracting attention as a gravure idol before expanding into variety television, films, television dramas and stage productions.

Her notable screen appearances include the films Seppun (Kiss) and Rebirth (Yōkame no Semi), the NHK historical drama The 13 Lords of the Shogun, the television series Kotatsu ga Nai Ie and Shinjuku Yasen Byoin, and Netflix's Tokyo Swindlers.

For her performance in Rebirth, Koike received an Excellence Award for Supporting Actress at the Japan Academy Film Prize. In the 2022 NHK historical drama The 13 Lords of the Shogun, she portrayed Hōjō Masako, bringing both strength and emotional sensitivity to the influential historical figure.

In 2023, Kotatsu ga Nai Ie marked her first leading role in a commercial television drama broadcast during Japan's prime-time evening hours. She then co-starred with Taiga Nakano in the 2024 medical drama Shinjuku Yasen Byoin, continuing to demonstrate her range as an actress.

In 2026, she starred in the NHK drama Mushoran Mitsuboshi, portraying Yoko Ginbayashi, a highly skilled restaurant chef who changes careers to become a dietitian working in a prison. The story's focus on food and human relationships offers an interesting connection to Koike's own well-documented love of eating.

From July to September that same year, Koike also starred in Fuji Television's Sayonara Noir. She played Natsumi Kuroki, a former organised-crime detective reassigned to a crime victim support unit, taking on a role centred on the experiences of victims and their families.

Her attitude towards work has evolved throughout her long career. When she was offered the leading role in Kotatsu ga Nai Ie, she initially felt that supporting roles suited her personality. However, watching fellow actor Shun Oguri devote himself wholeheartedly to creating a production during their time on The 13 Lords of the Shogun encouraged her to embrace a new challenge.

Away from the screen, Koike married former professional wrestler Wataru Sakata in 2007. Their long marriage has provided plenty of affectionate stories involving career advice, shared meals and everyday acts of care.

In a 2023 interview, she recalled hesitating over an appearance on a television prank programme. Her husband helped her recognise that it could introduce her to younger viewers. Afterwards, she found that children sometimes recognised her from the show, opening the door to a different generation of fans.

In 2024, she joked that she and her husband often spend time in the same room, which also happens to save money on lighting and heating or cooling.

Her shopping habits have changed over the years, too. She once enjoyed collecting cups for guests, wine glasses and candleholders. These days, when she sees something she wants, she may spend a couple of days thinking about it before deciding whether to buy it.

She also enjoys everyday public transport and shopping for household essentials on sale. At the same time, she likes being generous when sharing meals with friends and younger colleagues. This balance between practical living and warm hospitality is one of the appealing details of Koike's personality.

How Her Beauty Philosophy Changed in Her 40s: Advice from MEGUMI

Koike's relationship with beauty has changed along with her age and lifestyle.

At various points in her younger years, she became enthusiastic about gym workouts and beauty care. She has described herself as someone whose interests can change, preferring to explore different things and find what feels right at the time.

A major turning point in her skincare routine came through advice from MEGUMI, a fellow Japanese entertainer and beauty author.

In a 2023 interview with Biteki GRAND, Koike explained that she had started using sheet masks in the morning and evening after taking inspiration from MEGUMI's beauty advice and book.

As she moved through her 40s, Koike became more aware of how tiredness could show on her face. This encouraged her to pay closer attention to simple everyday skincare.

She has also reflected on how strongly she wanted to lose weight when she was younger. Today, she finds herself increasingly drawn to the character, experience and inner qualities of people rather than focusing solely on outward appearance.

Her approach combines an appreciation for the person she has become with a willingness to enjoy new beauty habits. It is a philosophy centred on feeling comfortable with herself at each stage of life.

2. Eiko Koike's Skincare, Sheet Masks and Makeup Habits

Morning and Evening Sheet Masks and Her Grandmother's Cleansing Advice

One of the most recognisable skincare habits Koike described in 2023 was using sheet masks both morning and evening.

At the time, she enjoyed affordable face masks bought from a discount store, costing around ¥700 for a pack of seven. She happily recalled receiving more compliments about her skin after adding them to her routine.

Choosing an accessible, reasonably priced product that she enjoys using regularly reflects her practical attitude towards beauty.

Another skincare habit has been part of her life for much longer: removing her makeup carefully.

Her grandmother, whom Koike remembered as having beautiful skin, taught her the importance of thoroughly removing makeup. Koike has continued to value that advice over the years.

As an actress, she often wears makeup for extended periods at work, making cleansing an important part of returning to her everyday routine. She has also spoken about purchasing her basic skincare products at ordinary drugstores.

Her approach brings together the familiar cleansing advice she inherited from her grandmother and the sheet mask routine she discovered in her 40s. The products and frequency described here reflect the time of the original interviews, but the underlying preference for practical, enjoyable skincare is an enduring theme in her story.

Minimal Makeup, Natural Skin and Her Attitude Towards Ageing

In her personal life, Koike enjoys a natural look, often wearing little or no makeup.

In 2024, she revealed that she uses cosmetics so slowly that she had bought foundation for the first time in approximately two years.

One detail she pays particular attention to when applying makeup is the impression created by her eyes.

Koike feels that her eyes already make a strong impression, and heavier makeup can sometimes make her expression seem more intense than intended. When communicating opinions at work, she therefore considers how others may perceive her and sometimes chooses a softer, more understated makeup style.

She is equally candid about the changes that come with ageing.

In 2023, she spoke about favouring familiar skincare habits and rarely visiting beauty salons. She also shared that she had once undergone a cosmetic procedure to address pigmentation after encouragement from her husband.

A particularly memorable example of her attitude towards her appearance came during her portrayal of Hōjō Masako in the NHK historical drama The 13 Lords of the Shogun.

Koike explained that her own pigmentation was incorporated into the makeup for Masako's later years. Rather than treating every visible sign of age as something to conceal, she allowed aspects of her own appearance to contribute to the story of a character who had lived through many experiences.

In 2025, she also spoke openly about noticing changes in how long facial puffiness and tiredness seemed to linger compared with her younger years.

Her everyday fashion is similarly relaxed. She enjoys T-shirts and jeans, while scarves and charms offer a way to give favourite handbags a fresh appearance and continue using them for longer.

Koike appeared in advertising for the skincare brand Takami in 2025. That professional endorsement is separate from the everyday products she has personally described in interviews, so her documented personal habits remain the focus of this article.

3. Eiko Koike's Diet: Rice, Miso Soup, Mushrooms and Manuka Honey

Two Onigiri for Breakfast: Her Love of Firm Rice and Rice Flour Desserts

Perhaps the most distinctive feature of Koike's eating habits is her deep love of rice.

In 2023, she described eating two onigiri, or Japanese rice balls, for breakfast. When having rice in a bowl instead, she would eat roughly one and a half bowls, and she also enjoyed rice in the evening alongside dishes such as meat and vegetables.

Koike and her husband both enjoy rice with a firmer texture. They prefer using a little less water when cooking it, taking pleasure in the way their everyday rice turns out.

Her enthusiasm also extends to rice-based sweets.

At a 2023 event related to rice and rice flour, she talked about discovering rice flour Swiss rolls at a favourite café. She particularly enjoyed their pleasantly chewy texture and sometimes chose one when she felt like a sweet treat.

In 2026, Koike named delicious sashimi served with white rice as one of her favourite meals to enjoy as a personal reward.

She likes buying small portions of several varieties of sashimi and enjoying them with freshly cooked rice. She even said that white rice would be her choice for the last meal of her life.

From breakfast onigiri to rice flour desserts and sashimi with steamed rice, rice is more than an everyday staple for Koike. It is a food that brings her genuine pleasure.

Hearty Miso Soup, Mushroom Dishes and Everyday Home Cooking

Koike loves eating, and she also adapts her meals to suit her work schedule and daily circumstances.

In 2023, she described a period of drama filming when she enjoyed whatever she wanted at lunchtime and chose hearty miso soup packed with ingredients for her evening meal.

She felt that the next morning her face looked a little different. This was her personal observation from that particular period rather than a general claim about the dish.

When she had several dinners or social events close together, she sometimes looked at her eating patterns over an entire week and chose lighter meals on other days.

In a 2026 interview, she also spoke enthusiastically about mushrooms.

She explained that her fondness for mushrooms had grown particularly strong over the previous three or four years. When she visits a greengrocer and discovers an unusual variety, she often feels tempted to buy it.

At home, she uses mushrooms in hot pots, stir-fries, simmered dishes and pasta.

She often enjoys straightforward home cooking, including hot pots and stir-fries. Earlier in life, however, she also loved hosting parties, sometimes shopping for ingredients from the morning and spending considerable time preparing food for guests.

Koike has even spoken about preferring to spend money on delicious vegetables rather than expensive cosmetics. Her pleasure in choosing ingredients and making meals she genuinely wants to eat is a recurring part of her lifestyle.

In 2026, she explained that even during busy filming periods, she likes to choose her own dinner and eat at home whenever possible. On days when she feels low, she may save a particularly favourite meal until she is in a better mood and can enjoy it fully.

Her role in the NHK drama Mushoran Mitsuboshi, which depicts food preparation within the restrictions of a prison kitchen, also made her reflect on the freedom to choose ingredients and plan meals.

Sharing meals with fellow actors matters to her as well. Sitting around a table encourages conversation and sometimes creates opportunities to discuss the production, personal concerns and ideas more openly.

Kombucha, Herbal Tea, Manuka Honey and Supplements

Koike has also discussed her preferences for drinks and small foods she keeps close at hand.

In 2023, she said she had been drinking a total of approximately one litre of detox tea and kombucha each day. She felt a change in her digestive comfort at the time, although this was her own personal experience.

Kombucha is a fermented tea drink enjoyed in many countries. It is different from Japanese konbucha, a traditional drink made with kelp.

Another interesting habit was carrying individually packaged portions of manuka honey.

She described enjoying the sweetness as a convenient little treat when she wanted to look after her throat or felt slightly hungry.

Manuka honey is closely associated with New Zealand, where it is a familiar specialty food. The specific brand and country of origin of Koike's own honey were not identified in the interview, but the habit provides an interesting connection to a food well known in New Zealand.

During the summer of 2024, Koike also discussed being mindful of temperature changes while filming and preferring to avoid very cold drinks even on hot days.

In 2025, she revealed that her husband, Wataru Sakata, had prepared supplements and drinks for her.

Concerned about her coming home tired from work, he would sometimes remind her to take them. At the time of the interview, she had only recently started the routine, about three days earlier. The story is particularly memorable as a small example of the care and attention within their marriage.

Whether enjoying a favourite meal, fermented tea or a little manuka honey, Koike approaches food and drinks with a sense of pleasure and flexibility that suits her everyday life.

4. Eiko Koike's Fitness, Dance and Physical Preparation for Acting

Her Dance Background and Preference for a Defined Arm Silhouette

Koike's confident physical expression on stage is connected to her experiences with dance when she was younger.

She devoted time to creative dance during her school years and later took on ballroom dancing challenges through television programmes.

During a beauty magazine photoshoot in 2023, the stability of her posture and the elegance of her poses were noted, reflecting the physical awareness she had developed through dance since her teenage years.

In a 2025 interview with VOCE, she also shared her personal preferences about the shape of her upper arms.

Koike likes wearing tank tops and rolling up the sleeves of her T-shirts, so the silhouette of her arms is something she pays attention to.

For her, the goal is an arm shape she personally finds attractive. She has sometimes felt that performing in stage productions brought her closer to that preferred silhouette.

Theatre also calls for a different kind of physical expression from television acting. She is conscious of using facial expressions and larger movements to communicate a character's emotions clearly, even to audiences seated far from the stage.

Her background in dance and years of theatre work have helped shape the way she moves, stands and expresses herself as a performer.

Role-Based Strength Training, Meal Planning and Vocal Care

Koike tends to approach exercise according to the needs of a role or a clearly defined goal.

She has enjoyed periods of enthusiasm for gym workouts and beauty care, while also describing herself as someone whose interests can change quickly.

In 2025, she explained that a specific deadline or target makes it easier for her to stay motivated. For example, she may work on building the muscles needed for a role or prepare her body for a stage performance.

She sometimes accompanies her husband to the gym, while walking her dogs gives her another opportunity to move during daily life.

During theatre runs, she may adjust her meal portions because eating too much before a performance can leave her feeling less comfortable moving on stage. For television dramas, costume fittings can also influence how she plans the timing and quantity of her meals.

At the same time, Koike enjoys her favourite foods. She has even mentioned occasionally eating an entire bag of potato crisps on a day off.

Looking after her voice is another important aspect of preparation for theatre.

In a 2025 interview ahead of the stage production Bakuretsu Chushingura: Sakura Fubuki THUNDERSTRUCK, she explained that her voice can become hoarse during a long performance run. She therefore hoped to rest her voice by speaking as little as practical outside performances.

From strength training to meal timing and vocal care, Koike adapts her physical preparation to the demands of the production. Her wellness habits are closely linked to her dedication to acting.

5. Sleep, Baths, Music and Relaxing with Her Dogs

Prioritising Eight Hours of Sleep and Enjoying Baths Even in Summer

Sleep is one of the things Koike places particular importance on while maintaining a busy acting career.

In 2023, she said she aimed for at least eight hours of sleep. She made time for rest as part of her daily routine and tried to give sleep the attention it deserved.

In 2024, she observed that working on a television drama could sometimes make her schedule more regular because there were fewer opportunities to stay up late.

She echoed this preference for rest in 2025, explaining that when she feels tired, she would rather prioritise sleep than exercise.

Bathing is another enjoyable part of her routine. In 2023, she described soaking in a bathtub even during the hot summer months, favouring bath products with hot-spring or herbal-inspired scents.

Her interest in fragrance goes back further. At one point, she enjoyed collecting different soaps, gradually discovering the types of scents she liked best as she tried them.

For Koike, getting enough sleep and enjoying a bath provide familiar moments in which she can leave the working day behind and return to her everyday life.

Listening to “Tomorrow” Before Bed and Checking In with Her Feelings

In a 2024 interview with Hanako Web, Koike shared an especially memorable bedtime habit.

She had been listening repeatedly to Tomorrow, the well-known song from the musical Annie.

Her favourite rendition was performed by Sydnie Christmas, a singer who appeared on a British television talent competition. During periods when Koike was working on dramas or theatre productions, she listened to this version every night before going to sleep.

She explained that listening to the same song helped her notice how her feelings changed from one day to another.

On a difficult day, the music might feel encouraging. On a happy day, she could listen with an equally bright mood. Hearing the familiar song allowed her to pay attention to her own emotional state.

When something is troubling her, she also values talking with people close to her and finding places or activities that help her feel settled.

Taking a moment to listen to music and recognise how she feels is a gentle, personal way for Koike to unwind.

Bonnie and Adrian: Enjoying Daily Walks and Conversations with Her Husband

Two beloved dogs bring considerable joy to Koike's home life.

She and her husband live with Bonnie and Adrian, two Miniature Schnauzers who are mother and daughter. In an interview from July 2026, they were described as eight and six years old respectively.

Bonnie's name was inspired by a character in the manga One Piece, while Adrian was named after the heroine of Rocky, a film loved by Koike and her husband.

Since welcoming the dogs into her life, Koike has found even more reasons to look forward to returning home after work.

In 2026, she said she hoped to take the dogs for walks twice a day whenever her schedule allowed. On mornings when work starts later, she sometimes stops at a nearby café for coffee during a walk.

In the evening, she and her husband often walk together, using the time to share the events of their day.

She also enjoys occasional stays at her family home and short overnight trips with friends and the dogs when she has time off.

Walking her dogs offers Koike a chance to move her body, enjoy a change of scenery and spend time talking with her husband. These ordinary moments have become an important part of her life outside acting.

6. Eiko Koike's Outlook on Health, Work and Life

How Her Priorities Changed in Her 40s: Health, Rest and Personal Growth

As Koike has moved through her 40s, she has become more thoughtful about her health and how she wants to spend her time.

In 2025, she reflected on noticing changes in how quickly she recovered from tiredness compared with her younger years, and on thinking more carefully about everyday habits as she looks to the future.

She laughed about how, when she was younger, she used to wonder why older adults talked about their health so often. Now she finds herself joining the same kinds of conversations.

Her attitude towards work has evolved as well. Earlier in her career, she found satisfaction in taking on many jobs. After the COVID-19 pandemic, however, she became more aware of how valuable time with herself and her family could be.

She has even said that an ideal balance might involve spending half her time working and the other half enjoying days off.

From her late 30s onwards, she also began to change the way she approached personal worries.

As a younger actress, she sometimes struggled with confidence and uncertainty about her future. Encouragement from others, along with the responsibility of taking on a wider range of roles, gradually helped her learn how to manage those feelings.

In a 2024 Hanako Web interview, she spoke about looking at her worries with greater perspective and appreciating the people around her and the ordinary experience of living each day.

Because she remembers the encouragement she received when she was younger, she now makes an effort to speak to younger actors and help them feel comfortable on set.

In 2023, Koike also revealed an amusing career ambition: she would love to play the heroine of an NHK morning drama at the age of 50.

Her attitude suggests that growing older can bring fresh possibilities. By welcoming new professional challenges while enjoying everyday life, Koike continues to find new ways to grow as an actress and as a person.

6 Surprising Facts About Eiko Koike

According to a story her mother told her, Koike had a remarkable appetite from the time she began eating solid food as an infant. She would even try to eat her older sister's portion. Her lifelong enthusiasm for food clearly began early.

2. A family restaurant was more memorable than a camping trip
When Koike was around 11 years old, she joined a camping trip with a friend's family. Both families struggled with the unfamiliar outdoor routine and returned to Tokyo earlier than planned. She remembers the hamburg steak, pizza and other food they enjoyed together at a family restaurant afterwards more fondly than the camping itself.

3. She once collected chopstick rests during theatre tours
During regional stage performances, Koike used to buy attractive chopstick rests whenever she came across them. She imagined using a different one every day in her new home, but after collecting so many, her enthusiasm suddenly moved on to something else.

4. She grew up surrounded by actors in Shimokitazawa
Koike spent her childhood in Tokyo's Shimokitazawa neighbourhood, where she sometimes saw well-known actors such as Akira Emoto and Naoto Takenaka around town. Her family ran a business, so she also had opportunities to interact with a wide variety of adults from an early age.

5. She enjoys watching dramas on her smartphone
In 2023, she revealed that she often carried her smartphone around the house and sometimes watched dramas while taking a shower. She also enjoys listening to music through earphones when she goes out, occasionally becoming so absorbed that she misses someone calling her name.

6. She and her husband are devoted fans of Rocky
Koike and her husband share a love of the Rocky films. They have displayed a poster at home and sometimes bought T-shirts featuring designs related to the movies. Their enthusiasm even inspired the name of their dog Adrian, after the film's heroine.

Looking at Eiko Koike's beauty and wellness habits reveals someone who enjoys finding everyday routines that suit her personality, circumstances and stage of life.

From the cleansing advice passed down by her grandmother to the sheet masks recommended by MEGUMI, and from minimal everyday makeup to a relaxed attitude towards ageing, her approach to skincare has evolved with her.

Her eating habits are full of personal favourites, including breakfast onigiri, firm-textured rice, hearty miso soup, mushrooms, kombucha and manuka honey. Sharing food with friends and family is just as important a part of her life as choosing ingredients she enjoys.
