Actress Haruna Kawaguchi has built a wide-ranging career across television dramas, films, commercials and other media, while also winning fans with her refreshingly down-to-earth personality. Alongside her clear-looking skin and glossy hair, the relaxed, approachable side she shares on her YouTube channel, “Haachan-ne-ru,” has become part of her appeal.
Born on February 10, 1995, in Nagasaki Prefecture, Kawaguchi grew up in the Goto Islands. In 2007, she won the Grand Prix in a model audition for the Japanese fashion magazine Nicola and began working as one of its exclusive models. She made her acting debut in the television drama Tokyo DOGS in 2009.
She went on to appear in numerous popular productions, including Kirin ga Kuru, Kikazaru Koi ni wa Riyuu ga Atte, silent, 9 Border and Ensemble. Her career has also expanded beyond acting, including serving as a host of NHK’s annual Kohaku Uta Gassen. Her screen work has continued in 2026 with projects including Kyojo Reunion and the film Mama ga Mou Kono Sekai ni Inakutemo Watashi no Inochi no Nikki.
In her personal life, Kawaguchi announced her marriage to Japan national football team player Ko Itakura, along with her pregnancy, in August 2026, marking a new chapter in her family life.
Having worked in the entertainment industry since her teens, Kawaguchi has developed a remarkably straightforward philosophy toward beauty and wellness: take care of the basics and choose what feels right for you at each stage of life.
Her skincare reflects that approach. For skin she has described as prone to dryness and fluctuations, she has spoken about applying toner around four times. During long shoots, when dryness becomes noticeable, she may even remove the makeup from below her eyes, moisturize her skin and then have her makeup reapplied.
Her hair routine has included treatments, careful blow-drying and scalp care, while her approach to inner care has included iron, zinc, protein and vitamin C.
Her exercise habits are equally varied, ranging from Pilates and kickboxing to swimming, yoga and walks with her dog. Sleep, sauna sessions, massage and time with family also form part of the broader lifestyle she values.
Here, we take a detailed look at Haruna Kawaguchi’s beauty and wellness routine, including skincare, moisturizing, cleansing, sun protection, hair and scalp care, supplements, diet, exercise, sleep, sauna, self-care, family life and her memorable connection with New Zealand.
Haruna Kawaguchi’s Skincare Routine: Hydration, Cleansing and Sun Protection
Looking at Kawaguchi’s skincare habits over the years, one principle appears consistently: she pays close attention to the fundamentals of cleansing, washing, moisturizing and sun protection.
She has described her skin as being prone to dryness and fluctuations in condition.
In a 2023 interview, Kawaguchi revealed a particularly specific hydration habit: she would generously apply toner around four times, both morning and night.
At the time, her basic routine followed this order:
Booster → toner → serum → cream.
She adjusted the final step according to the time of day, using cream more generously at night and keeping the morning application lighter.
In 2025, she again emphasized the basics she follows every day: thoroughly removing makeup, moisturizing well and protecting her skin from UV exposure.
Rather than treating skincare as a fixed formula, she pays attention to how her skin feels and builds her routine around consistent daily care.
💡 Beauty Note: Toner Around Four Times
In 2023, Kawaguchi shared that she layered toner around four times. Her routine included a booster, toner, serum and cream, with adjustments between morning and evening.
Re-Moisturizing Her Skin During Long Shoots
An actress may spend many hours wearing makeup on set, and Kawaguchi has developed practical ways to care for her skin during those long working days.
In a 2021 interview, she explained that she takes moisturizing very seriously.
When her skin begins to feel dry during an extended shoot, she may remove the makeup from below her eyes, moisturize the area and then have the makeup reapplied.
She also likes to remove her makeup and wash her face relatively soon after returning home. During seasons when her skin feels more sensitive or unsettled, such as pollen season, she adjusts her care according to its condition.
💡 Beauty Note: A Mid-Shoot Makeup Reset
When dryness becomes noticeable during a long shoot, Kawaguchi has described removing the makeup from below her eyes, moisturizing her skin and then having the makeup reapplied—a very specific beauty habit shaped by her work as an actress.
How Her Cleansing and UV Care Have Evolved
One of the most interesting aspects of Kawaguchi’s beauty routine is how it has evolved with experience.
Her awareness of sunscreen and the importance of properly removing makeup has grown over time. Cleansing, face washing, moisturizing and UV care are now among the everyday basics she prioritizes.
Spending more time at home during the pandemic also gave her an opportunity to pay closer attention to her own skin.
In 2024, she spoke about noticing differences in how she feels the next day depending on how she spent the previous day and what she ate.
She remains open to beauty information and advice from people around her, selecting what suits her and continuing to update her routine with the future in mind.
Turning Former Insecurities Into Individual Beauty
Another revealing part of Kawaguchi’s beauty philosophy is the way her relationship with her own features has changed.
In 2022, she spoke about once feeling self-conscious about her hooded eyelids and broad forehead.
Her perspective gradually shifted when people around her complimented the very features she had worried about.
She came to appreciate how distinctive features can create individuality and character. She has also spoken positively about beauty that allows natural details such as moles and freckles to remain visible.
When considering a new hairstyle, she may even ask members of her team for their opinions. Her approach leaves room for seeing herself through the eyes of people she trusts.
💡 Beauty Note: From Insecurity to Individuality
Kawaguchi once felt self-conscious about features including her eyes and forehead. Over time, encouragement from people around her helped her see those same characteristics as part of her individuality.
Her Morning Starts With Teeth, Face Washing and Skincare
Kawaguchi has also shared a realistic morning routine on her YouTube channel.
She considers herself relatively comfortable with mornings, beginning her day with a simple sequence of brushing her teeth, washing her face and doing her skincare.
Preparing her skin in the morning has become a natural part of how she starts the day.
Iron, Zinc, Protein and Vitamin C in Her Inner-Care Routine
Alongside topical skincare, Kawaguchi has spoken specifically about her approach to inner care.
In 2019, she discussed incorporating nutrients such as iron after checking her own condition.
By 2023, she had also spoken about paying attention to iron and zinc, while incorporating protein and vitamin C into her routine.
Food remains the foundation of her approach, with supplements and other choices added according to what suits her at the time.
Haruna Kawaguchi’s Hair and Scalp Care Routine
Hair care is another area to which Kawaguchi has devoted considerable attention.
In 2021, she described herself as someone who pays particular attention to caring for her hair.
Acting work involves frequent styling, while different roles may require changes in hairstyle, making everyday maintenance especially relevant to her routine.
Two of the basics she has emphasized are regular hair treatments and careful blow-drying.
She has also spoken about updating her hair dryer and consistently using treatments as part of her ongoing routine.
💡 Beauty Note: She Updates Her Hair Dryer Too
Because her work involves frequent styling, Kawaguchi pays close attention to her hair. Regular treatments and updating the tools she uses have both formed part of her routine.
In 2025, Hair Care Began Before Shampooing
In 2025, Kawaguchi shared an even more detailed approach to her nighttime hair routine.
She emphasized washing the hair properly, moisturizing it and drying it thoroughly.
She also described using a kassa-style comb as part of her scalp-care routine before washing her hair.
She demonstrated using the thicker side before shampooing and the finer side after washing while working treatment through her hair.
Fragrance is another part of the experience she enjoys. Pleasant scents can turn her hair-care routine into a relaxing part of the evening.
From hair dryers and treatments in 2021 to a greater focus on pre-wash scalp care in 2025, her routine has continued to evolve while retaining its emphasis on everyday maintenance.
💡 Beauty Note: Hair Care Starts Before Washing
Kawaguchi has introduced scalp care with a kassa-style comb before shampooing, alongside the basics of washing, moisturizing and thoroughly drying her hair.
Haruna Kawaguchi’s Exercise Routine: Pilates, Kickboxing, Swimming and Yoga
Kawaguchi’s approach to exercise reflects her personality particularly well.
She chooses different forms of movement according to what suits her at the time, with enjoyment and comfort playing an important role.
Pilates for Around Two Years, With Once a Week as a Goal
In a 2023 interview, Kawaguchi said she had been practicing Pilates for around two years at that point.
Her goal was approximately once a week.
She enjoyed the sensation of stretching her body and the comfortable feeling afterward, making Pilates an activity that suited her well.
💡 Wellness Note: Pilates About Once a Week
By 2023, Kawaguchi had been practicing Pilates for around two years, aiming for roughly one session a week while keeping the routine comfortable and sustainable for herself.
Kickboxing Works Because She Can Enjoy It With Someone
Another activity Kawaguchi has incorporated into her routine is kickboxing.
In 2024, she explained that exercise with a trainer, where movement can feel more like a game or sport, suits her personality.
The interaction and sense of enjoyment that come from moving with another person appear to be part of what makes this style of training appealing to her.
Swimming for an Hour With Her Mother
Swimming has also been one of Kawaguchi’s favorite ways to stay active.
She has gone swimming with her mother and, during one period, became absorbed in swimming continuously for around an hour.
She has recalled enjoying the pleasantly tired feeling afterward and looking forward to sleeping that night.
💡 Wellness Note: An Hour in the Pool With Her Mother
Exercise and family time naturally overlapped for Kawaguchi. At one point, she enjoyed swimming continuously for around an hour when visiting the pool with her mother.
Walking Her Dog Once or Twice a Day
Her active time is not limited to studios or gyms.
In 2021, Kawaguchi said that having a dog meant she would go outside for walks once or twice a day.
She has also enjoyed taking her dog to the park, relaxing on a picnic sheet and going camping with her family.
Even during busy periods, she has continued to value personal time and the balance between work and everyday life.
From Yoga to Dreams of a Full Marathon and Mount Fuji
In 2026, Kawaguchi also mentioned yoga as part of the personal maintenance she enjoys on a day off.
Looking ahead, she has expressed interest in challenges that require more time, including running a full marathon and climbing Mount Fuji.
Pilates, kickboxing, swimming, walking and yoga all show the same pattern: she keeps movement varied and chooses activities she can genuinely enjoy.
Haruna Kawaguchi’s Diet: Japanese Food, Vegetables, Rice and Eating Her Way
Looking at Kawaguchi’s eating habits over time reveals a process of trying different approaches and gradually discovering what feels sustainable for her.
In 2019, she spoke about drinking plenty of water and choosing foods such as fruit and roasted sweet potatoes that allowed her to enjoy simple ingredients.
When cooking at home at the time, she focused largely on Japanese-style meals with plenty of vegetables.
She also liked vinegared dishes and would prepare larger batches to keep on hand and eat little by little.
💡 Food Note: Keeping Vinegared Dishes Ready
In 2019, Kawaguchi described a home-cooking style centered on Japanese food and vegetables, including preparing batches of her favorite vinegared dishes to enjoy over several meals.
Finding an Eating Style That Suits Her
Kawaguchi has experimented with different approaches to eating in the past, including periods of reducing carbohydrates and trying juice cleanses.
Those experiences helped shape an approach centered on choosing food in a way that feels appropriate for her body, mood and lifestyle.
During particularly busy periods in 2019, she sometimes aimed to finish dinner by around 7 p.m.
She would also pay attention to how she felt the following morning and use that awareness when considering the timing of her meals.
By 2023, she was speaking about eating what she genuinely wanted at the time, while in 2024 she described a broader lifestyle philosophy of avoiding too many rigid personal rules.
In 2025, Two Large Bowls of Rice on Some Days
One of the more memorable insights into Kawaguchi’s relationship with food came from her YouTube channel in 2025.
When she eats, she can eat heartily—and she especially loves rice.
She explained that a standard serving of rice with a set meal may sometimes feel a little small, leading her to order more. On days when she has a bigger appetite, she may eat the equivalent of two large servings of rice.
Her appetite varies with her work schedule and circumstances, but the story reflects the importance she places on enjoying food.
💡 Food Note: She Really Loves Rice
In 2025, Kawaguchi revealed that she can eat heartily when she is hungry, particularly when it comes to rice, sometimes having the equivalent of two large servings.
Enjoying Restaurants While Making Her Own Food Choices
In 2024, Kawaguchi discussed becoming more aware of how what she eats one day may correspond with how she feels the next.
She enjoys both home cooking and eating out, adapting to her schedule and circumstances.
Among her personal choices at the time was an effort to limit wheat when practical.
She also enjoys alcohol, balancing the foods and drinks she likes with an awareness of her everyday condition.
Her Mother’s Large Pot of Oden: A Food Memory From Goto
Kawaguchi grew up in the Goto Islands of Nagasaki Prefecture, and some of her strongest food memories are connected to family.
One dish she remembers particularly fondly is her mother’s oden, a Japanese hot-pot dish.
When the weather turned cold, her mother would fill a large pot with ingredients and slowly simmer them. Gathering around that pot became part of the family’s winter scenery.
From vegetables and vinegared dishes to rice, restaurant meals and her mother’s oden, Kawaguchi’s food story reflects an approach centered on listening to herself while continuing to enjoy eating.
Haruna Kawaguchi’s Sleep, Sauna and Self-Care Routine
For Kawaguchi, beauty and wellness extend well beyond skincare and exercise.
Sleeping, massage, sauna sessions, listening to music and simply relaxing at home all have a place in her personal routine.
Small moments that lift her mood are also part of the way she cares for herself.
Her Ideal Sleep Is 8 to 10 Hours
Kawaguchi has described herself as someone who loves sleeping.
When asked about sleep in 2022, she said her ideal amount was eight to ten hours.
Even seven hours can feel a little short to her. During demanding production periods, however, she has experienced days when she gets only two or three hours of sleep.
Because her schedule can vary dramatically, she values opportunities to rest when they are available.
💡 Wellness Note: Her Ideal Is 8–10 Hours of Sleep
In 2022, Kawaguchi said that even seven hours could feel a little short for her. During busy productions, however, her sleep has sometimes dropped to only two or three hours.
When Work Even Appears in Her Dreams
During filming periods, Kawaguchi’s intense focus on work can even carry over into sleep.
In 2021, she said that while working on a drama or other production, she could remain so mentally focused on the job that her sleep sometimes felt shallow.
Before important filming days, she has even dreamed about forgetting her lines or arriving late.
Once she has prepared as much as she can, she also values switching gears mentally and enjoying the experience on set.
Nighttime Self-Care and Her Awareness of Feeling Cold
When sharing her nighttime routine in 2021, Kawaguchi described herself as someone who tends to feel cold easily.
After bathing, she would wear leg warmers and use cream while caring for areas including her legs, soles of the feet, décolletage, collarbone area and head.
After busy days on set, this gave her time at home to slow down and pay attention to her body.
Her 2023 Sauna Routine: About Twice a Week
Kawaguchi also went through a period when sauna became one of her favorite activities.
In a 2023 YouTube video, she said she was going around twice a week at the time.
Her personal routine then consisted of approximately 12 minutes in a sauna at around 90°C, followed by four minutes in water at about 17–18°C, repeated for four rounds.
She had previously been uncomfortable with both saunas and cold-water baths, but gradually discovered a way of enjoying the experience for herself.
💡 Wellness Note: Her Very Specific Sauna Routine
In 2023, Kawaguchi described this as her own routine at the time: roughly 12 minutes in the sauna followed by four minutes in cold water, repeated for four rounds, with visits around twice a week.
Good Food, Drinks and Music Can Lift Her Mood
In 2025, Kawaguchi named things such as delicious food, foods she genuinely wants to eat, drinks and music among the everyday pleasures that lift her mood.
She values the small moments in ordinary life that bring a sense of excitement or enjoyment.
Some days off may include a salon appointment, yoga or massage, while others are spent simply relaxing at home. That flexibility is an important part of her current approach to self-care.
Haruna Kawaguchi’s Beauty Philosophy: Family, Marriage, New Zealand and Living Naturally
Looking at Kawaguchi’s beauty and wellness habits across many years reveals more than individual skincare products or workouts. It also reveals the kind of person she wants to be.
The Kind of Smile That Reveals a Life Well Lived
In 2022, Kawaguchi spoke about her belief that a person’s way of living can be reflected in their face.
One example she shared was the woman who runs a neighborhood restaurant she knows.
Kawaguchi was drawn to a smile that seemed to reflect the experiences and years behind it.
That idea connects naturally with her own journey of gradually accepting features she once viewed as insecurities.
For Kawaguchi, beauty encompasses cosmetics and skincare while also extending to how someone lives each day and the expression they carry through life.
💡 Beauty Note: A Smile That Tells a Life Story
Kawaguchi once used the smile of a neighborhood restaurant owner as an example of the beauty she admires—an expression that seems to reflect the life a person has lived.
Her Mother, Grandmother and Dog: Staying Close to Family
Family and her dog repeatedly appear in Kawaguchi’s descriptions of the times when she feels most like herself.
She has gone swimming with her mother, taken her dog for walks, relaxed together in parks and enjoyed camping with family.
In 2022, she spoke about feeling particularly lively when she was with family and her pets.
In 2024, she also discussed the importance of family in her priorities and revealed that she video-called her family every day.
She has spoken fondly about her grandmother in Nagasaki as well, showing how regular communication helps her stay connected even when family members live far apart.
Alongside a demanding career, these ordinary relationships remain an important part of the balance between her work and personal life.
Marriage to Ko Itakura and a New Chapter of Family Life
In August 2026, Kawaguchi announced her marriage to Japan national football team player Ko Itakura and her pregnancy.
In their joint announcement, the couple expressed their intention to support one another and build a home filled with smiles.
Family has long been woven into Kawaguchi’s story—from growing up in Goto to memories of her mother’s cooking and swimming together, as well as life with her dog.
In a 2026 interview after her marriage, she also named home as a place where she can truly relax, describing ordinary moments such as cooking, eating and watching television as meaningful parts of daily life.
Her First Visit to New Zealand Brought Out Her Natural Side
Kawaguchi also has a direct connection with New Zealand.
In 2024, she traveled there to film a cosmetics commercial. It was her first visit to New Zealand.
She recalled the calm pace of the country and how relaxed she felt while filming there.
Kawaguchi felt that this relaxed state helped her natural personality come through on camera. She enjoyed New Zealand so much that she said she wanted to return.
Food was another memorable part of the trip. She recalled enjoying what she ate wherever she went during her stay.
For the commercial, she also tried a natural pink-toned makeup look with a fresh, understated glow, enjoying the opportunity to see a slightly different side of herself.
💡 New Zealand Note: Her First Visit Became a Favorite Memory
Kawaguchi’s first trip to New Zealand was for a commercial shoot. She enjoyed the calm atmosphere, relaxed naturally during filming, loved the food and came away wanting to visit again.
Consistency, Flexibility and Choosing What Feels Right
If there is one theme connecting Kawaguchi’s beauty and wellness habits, it is learning about herself and building routines she can continue.
When her skin feels dry, she adds more hydration. She continues hair treatments while remaining open to new approaches to scalp care.
She stays active through Pilates, kickboxing, swimming, walking and yoga, choosing movement she can enjoy at different stages of life.
Her relationship with food has evolved through experience too. Vegetables, rice, restaurant meals and favorite foods can all have a place while she pays attention to how she feels.
Rest may mean sleep, massage, sauna, time with family and her dog, good food, music or simply being at home.
In 2024, after experimenting with different habits over the years, Kawaguchi spoke about the importance of choosing things that feel comfortable and enjoyable enough to continue.
She observes how she feels and makes choices that suit the day. That flexibility exists alongside her commitment to simple skincare and hair-care fundamentals.
From growing up in the Goto Islands to entering the entertainment industry as a teenager, building a long acting career and beginning a new chapter of family life, Kawaguchi’s circumstances have continued to change.
Her approach to beauty and wellness has evolved with them.
Take care of the basics. Stay flexible. And make room for the things that make everyday life feel good.
Haruna Kawaguchi’s beauty and wellness routine is ultimately about more than caring for skin and hair. It reflects an approach to life built around accepting her individuality, valuing family and everyday moments, and continuing to discover what feels right for her.
