After beginning her career as a fashion model, Koyuki went on to become one of Japan’s most recognizable actresses, appearing in numerous films and television dramas as well as the Hollywood film The Last Samurai. Known for her elegant presence and natural beauty, her approach to beauty and wellness extends far beyond skincare alone.
Born on December 18, 1976, in Kanagawa Prefecture, Japan, Koyuki began working as a model in 1995, including as an exclusive model for the fashion magazine non-no. She made her acting debut in 1998 in the television drama Koi wa Aserazu and appeared in The Last Samurai in 2003. For the 2005 film Always: Sunset on Third Street, she received an Outstanding Performance by an Actress in a Leading Role award at the 29th Japan Academy Film Prize.
She has since built a career spanning more than three decades across fashion, film and television. Her credits include the Always series, Persona Non Grata, Sakura iro no kaze ga saku, Fumō Chitai, Daibinbō, The Naked Director, Boogie Woogie, Sky Castle and Dr. Ashura.
In her personal life, Koyuki married actor Kenichi Matsuyama in 2011. The couple welcomed three children in 2012, 2013 and 2015, and Koyuki is now a mother of three.
Her family has also experienced a lifestyle that combines city life with time spent in a more nature-rich environment. Growing food, encountering seasonal ingredients and spending time outdoors have become part of the broader story of how Koyuki approaches everyday life.
In recent years, another subject has become closely associated with Koyuki: fermentation.
Through the NHK Educational TV program Koyuki to Hakkō Obāchan, she has traveled around Japan meeting people who preserve regional traditions involving miso, pickles, fermented teas and other foods. The program was adapted into a book in 2025, while her exploration of Japan’s fermentation culture has continued.
What makes this especially interesting is that her fascination with fermented foods did not begin recently.
Koyuki grew up eating brown rice, miso soup, umeboshi and simmered dishes. After becoming a mother herself, foods such as miso soup, natto and amazake also became familiar parts of meals for her own family.
Simplifying skincare. Caring for the scalp and hair. Enjoying brown rice and fermented foods. Staying active. Spending time in nature. And choosing forms of care and rest according to how she feels at each stage of life.
Here, we take a detailed look at Koyuki’s beauty and wellness routine, including her skincare, lotions and creams, scalp and hair care, diet, brown rice and fermented foods, cooking habits, approach to dieting, exercise and stretching, self-care after three pregnancies and births, marriage to Kenichi Matsuyama, life as a mother of three, connection with nature, and her beauty philosophy at age 49.
Koyuki’s Skincare Routine at 49: Simplicity, Lotion and Cream
After decades of working in fashion and acting, Koyuki’s approach to skincare has become increasingly simple as she has grown older.
In a 2021 beauty interview, she spoke about how her skincare routine had become simpler with age.
Having experienced many beauty methods and cosmetic products throughout her career, she now places importance on observing the condition of her own skin and body and choosing care that feels appropriate at that particular time.
Her everyday makeup can also be relatively minimal. In the same interview, she explained that there are days when she wears very little base makeup, relying instead on touches such as eyeliner and lip gloss.
Professional makeup remains part of her work for films, television and photo shoots, while her private routine can be much lighter. This distinction between professional beauty and everyday care is one of the most interesting aspects of her approach.
💡 Beauty Note: Her everyday makeup can be surprisingly minimal
Although Koyuki has experienced countless makeup looks throughout her career, her everyday style can be as simple as eyeliner and lip gloss with very little base makeup. Her preference reflects a beauty routine shaped by years of learning what feels comfortable for her.
More recent interviews connected with her role as a beauty brand ambassador also offer insight into her current beauty philosophy.
When choosing cosmetics, Koyuki values how they feel through the senses, including their fragrance and texture. She has described skincare as time that allows her to reconnect with herself.
During a brand photo shoot, products she favored at the time included a lotion, cream and skin fragrances.
Because these details were shared in the context of her ambassador work, they are best understood within that setting. What is particularly revealing is the way she evaluates beauty products through sensory experience, including scent and how a product feels on the skin.
Even small moments during a busy day can become opportunities for self-observation. When checking her makeup after lunch, for example, looking in the mirror can also become a moment to notice how her skin — and she herself — feels that day.
💡 Beauty Note: At 49, she chooses skincare through the senses
Fragrance, texture and the feeling a product creates are all part of Koyuki’s approach. During a beauty brand shoot, her preferences included lotion, cream and skin fragrances, reflecting the importance she places on sensory comfort.
A key to understanding Koyuki’s beauty philosophy is that beauty and wellness are closely connected in her lifestyle.
Skin, food, physical condition, emotions and rest all form part of how she observes herself. This perspective can also be seen in her book Koyuki Bi no Yōjōkun and in her more recent work exploring fermented foods.
Koyuki’s Hair, Scalp and Exercise Habits: From Running to Postpartum Self-Care
One distinctive feature of Koyuki’s beauty routine is that she extends her attention beyond the face to include the scalp and hair.
In a 2021 interview, she shared a specific step in her hair-washing routine.
Before shampooing, she thoroughly wets the scalp with water and then proceeds with shampoo.
Just as she pays attention to facial skincare, she also gives thoughtful attention to the scalp as the foundation of her hair-care routine.
💡 Beauty Note: Water comes before shampoo
Koyuki has described thoroughly wetting her scalp before using shampoo. It is a small but very specific example of the attention she gives not only to her hair, but also to the scalp beneath it.
Behind these beauty habits is a long history of observing her own body throughout her modeling and acting career.
Koyuki has recalled being highly active when she was younger. Until around the age of 30, there were times when she would even go running after finishing work.
After beginning modeling work while still young and experiencing demanding schedules, she gradually became increasingly attentive to her body and eating habits.
Marriage, pregnancy, childbirth and parenting later brought new stages of life, and her approach to caring for her body evolved along with them.
A particularly significant period was the roughly five years in which she experienced three pregnancies and births.
Her 2016 book Koyuki Bi no Yōjōkun reflects on that period and the ways she explored everyday self-care, including food, stretching, phytotherapy, aromatherapy and traditional Japanese and Chinese herbal approaches.
💡 Wellness Note: Three births across roughly five years
In Koyuki Bi no Yōjōkun, she documented experiences from the period surrounding her three pregnancies and births, including her exploration of food, stretching, plants and fragrance as part of caring for herself.
From running in her younger years to stretching and sensory forms of self-care during a very different stage of life, Koyuki’s habits show how her approach has evolved with age and changing circumstances.
Koyuki’s Diet: Fermented Foods, Brown Rice, Miso Soup and Amazake
To understand Koyuki’s approach to beauty and wellness, one subject deserves particular attention: food.
Many people may now associate her interest in fermented foods with the NHK Educational TV program Koyuki to Hakkō Obāchan.
Yet when her eating habits are traced back to childhood, her current fascination with fermentation appears as part of a much longer story.
At the beginning of that story is her mother.
Her mother placed considerable importance on the family’s meals and even prepared sprouted fermented brown rice at home by soaking brown rice to encourage sprouting, cooking it and keeping it warm afterward.
From around the age of five, Koyuki was already familiar with brown rice served with sesame salt, umeboshi, simmered dishes and miso soup. Small fish were also among her childhood snacks.
She has recalled that fish played a central role in her childhood diet and that there was a period when meat was served only about once a month.
💡 Food Note: Brown rice has been on her table since around age five
Koyuki grew up eating brown rice, but as a child she sometimes wondered why the rice was brown instead of white — a charming contrast with the deep interest she now has in traditional foods and fermentation.
Her childhood home also included another unusual tradition: loquat leaves from the garden were boiled to make loquat-leaf tea.
Brown rice, umeboshi, miso soup, fish and loquat-leaf tea all formed part of an early food environment that helped shape her lasting curiosity about what she eats.
Passing Miso Soup and Fermented Foods on to Her Three Children
After becoming a mother herself, Koyuki began bringing aspects of the food culture she had grown up with into meals for her own three children.
In a 2020 interview, she explained that she was serving her children miso soup in the morning and evening and aiming at the time to include approximately one fermented food, such as natto, with each meal.
Her children had become so familiar with these foods that they would ask for miso soup and rice with natto.
Her miso-soup routine also reveals the practical side of balancing work with raising three children. Sometimes she prepared it at night, while on other occasions she made extra at dinner and added new ingredients when reheating it the following morning.
Her interest in fermentation also extends beyond miso soup and natto into everyday cooking.
She has used amazake in place of sugar in simmered dishes and has made her own miso. In 2020, she said that she was making five different varieties of miso.
💡 Food Note: Amazake in cooking — and five kinds of homemade miso
From using amazake to add sweetness to simmered dishes to making several varieties of miso herself, fermented foods have become familiar ingredients in Koyuki’s everyday cooking.
Koyuki’s Approach to Dieting: Long-Term Eating Habits Matter
Given Koyuki’s long career as a model and actress, searches for her “diet,” “eating habits” and beauty routine are understandable.
What stands out most when looking at her eating habits over many years, however, is the long-term foundation of her diet.
Brown rice, miso soup, umeboshi, simmered dishes, fish, natto and amazake have all appeared in her food story, while her adult life has brought an even broader interest in seasonal ingredients and regional fermented foods.
Her approach places emphasis on what can become part of an everyday table and how food traditions can remain part of life over time.
Brown rice and fermented foods are therefore best understood as elements within the broader eating habits Koyuki has valued for many years.
During the years surrounding her pregnancies and births, her interest also expanded to stretching, plants, fragrance and other forms of self-care.
Food, beauty, movement and rest all sit within a larger lifestyle in which she adapts her choices to her circumstances and how she feels.
From Childhood Brown Rice to Koyuki to Hakkō Obāchan
Today, the clearest expression of Koyuki’s fascination with food is the NHK Educational TV series Koyuki to Hakkō Obāchan.
The program takes her around Japan to meet people who have spent years preserving local fermented-food traditions. Along the way, she explores not only recipes but also climate, history, preservation methods and the everyday knowledge behind these foods.
Her journeys have introduced her to a remarkable range of regional fermentation traditions, including godo in Aomori, sunki in Kiso, Nagano, nari miso in Amami, Kagoshima, fermented salted natto in Kyoto, Ishizuchi fermented tea in Ehime, Kinzanji miso in Wakayama and batabata-cha in Toyama.
A special episode with culinary expert Yoshiharu Doi also explored fermentation through the Japanese concept of ichiju-issai, a simple meal centered around one soup and one accompanying dish.
In November 2025, the program was adapted into the 280-page book Koyuki to Hakkō Obāchan, bringing together fermented foods, the people who make them and the lifestyles surrounding these traditions.
💡 Food Note: From brown rice at age five to exploring fermentation across Japan
Koyuki grew up with brown rice and miso soup. Decades later, she now travels around Japan meeting people who preserve regional fermentation traditions — connecting a childhood food culture with her work today.
One of the foods she has highlighted as a favorite is sunki, the traditional fermented turnip greens of Kiso. She has even paired it with mozzarella on pizza.
Learning the history of traditional fermented foods, meeting the people who keep those traditions alive, and then finding enjoyable ways to bring them into contemporary meals reveal the flexibility and curiosity at the heart of Koyuki’s relationship with food.
Koyuki’s Self-Care: Nature, the Senses and How She Spends Her Days Off
In Koyuki’s current approach to beauty and wellness, time spent reconnecting with her own senses has become just as meaningful as food and skincare.
In a recent interview, she spoke about intentionally spending less time looking at her smartphone on days off and making more time to connect with nature.
Time outdoors gives her space to notice what she likes and what feels comfortable to her. This echoes the same sensory awareness she brings to skincare when considering fragrance and texture.
For Koyuki, self-care has expanded into something woven through ordinary life — small opportunities to bring her attention back to herself.
💡 Wellness Note: Less smartphone time, more time in nature
On her days off, Koyuki makes an effort to reduce smartphone time and spend more time in nature. Like her sensory approach to skincare, it gives her space to notice what feels comfortable and meaningful to her.
This perspective also connects with the period surrounding her three pregnancies and births, when she explored food, stretching, plants and fragrance while finding forms of self-care suited to that stage of her life.
The woman who once had enough energy to run after work has gradually expanded her routine to include nature, sensory awareness and time to turn her attention inward as her life and priorities have changed.
Choosing what suits her at a particular stage rather than following one fixed routine has become an important thread running through Koyuki’s approach to self-care.
Marriage to Kenichi Matsuyama and Raising Three Children
Koyuki married actor Kenichi Matsuyama in 2011.
Their three children were born in 2012, 2013 and 2015. Koyuki has continued acting while also building a family life as a mother of three.
One significant chapter for the family involved spending time between Tokyo and a more nature-rich area of Japan.
The family has grown a variety of produce, including cherry tomatoes, watermelon, Kujo green onions, strawberries and herbs, while the children have had opportunities to experience insects, living things and seasonal changes around them.
This lifestyle also fits naturally with Koyuki’s interest in food. Alongside preparing ingredients in the kitchen, growing produce offered the family a chance to see how food develops and to experience the changing seasons more directly.
💡 Family Note: Tomatoes, watermelon, strawberries and herbs from the family garden
During the family’s time in a nature-rich environment, they grew a variety of produce. Gardening, wildlife and the changing seasons became part of the children’s everyday experiences.
The family’s lifestyle has also evolved as the children have grown older.
According to reports about a television appearance by Koyuki in January 2026, the family had previously experienced a two-base lifestyle involving Tokyo, while Matsuyama now continues that two-base arrangement.
In the same television appearance, Koyuki spoke candidly about parenting their three children as they have grown older.
She also shared glimpses of everyday family life, including how the couple can have different perspectives on parenting and how the children sometimes come to talk with her while she is preparing meals.
Her humorous stories about dividing household responsibilities with Matsuyama reveal a more everyday side of the actress — one shaped by the realities of raising three children alongside a long professional career.
💡 Family Note: Life with three growing children at 49
Koyuki spoke openly in 2026 about life with her three children as they grow older, offering a glimpse of the mother and family member behind her composed public image.
Nature, parenting, acting and the everyday family table have all changed shape over the years. Koyuki’s story shows a family lifestyle that continues to evolve with each stage of life.
What We Can Learn from Koyuki’s Beauty and Wellness Philosophy at 49
Looking at Koyuki’s beauty and wellness habits across several decades reveals one consistent theme: she has continued adapting her lifestyle to what feels appropriate for each stage of her life.
Her childhood food culture, years as a model and actress, three pregnancies and births, raising three children, experiences in nature, and her current journeys through Japan’s regional fermentation traditions all form part of the same story.
The individual methods have evolved, but her attention to skin, scalp, food, physical condition, emotional wellbeing, nature and family remains connected through everyday life.
At 49, her beauty philosophy has expanded into something broader: how a person chooses to live, what they value, and how they care for themselves over time.
💡 At 49, beauty has become part of a wider way of living
From modeling and acting to three births, parenting and a life increasingly connected with nature, Koyuki has continued adjusting her habits to suit each stage. Her current beauty philosophy reaches beyond appearance into the way she chooses to live each day.
Perhaps the most compelling part of her story is the way food connects generations.
Koyuki grew up eating the brown rice and miso soup prepared by her mother. Years later, she brought miso soup and natto to the table for her own children. Today, she travels around Japan listening to people who preserve regional fermentation traditions and sharing their knowledge with a wider audience.
The everyday wisdom she encountered as a child has continued for more than four decades, connecting her family life, professional work and interest in passing traditional food culture to future generations.
That continuity is what makes Koyuki’s story much richer than a simple list of celebrity beauty tips.
At 49, Koyuki presents an approach in which beauty and wellness are connected with everyday food, family, nature and the way she chooses to live.
