Kento Yamazaki's Beauty & Wellness Routine | Skincare, Fitness & Diet

Actor Kento Yamazaki has earned attention in Japan and internationally through leading roles in major productions, including the Kingdom and Golden Kamuy films and the Netflix series Alice in Borderland.

Born on September 7, 1994, in Tokyo, Japan, Yamazaki made his acting debut in 2010. Since then, he has taken on a wide range of roles, from romantic dramas to large-scale action productions.

A closer look at his beauty and wellness habits reveals a collection of surprisingly specific personal routines: using a facial sheet mask before bed, keeping his skin moisturized, changing his pillowcase, carefully drying his hair, practicing scalp massage, and enjoying saunas and hot springs.

In 2021, he spoke about aiming to drink two liters of water a day. In 2024, he discussed alternating hot baths with cold showers at home and his preference for fitting exercise into roughly an hour. By 2026, he revealed that he often began his day with a workout.

His physical preparation for acting is equally remarkable. He lost approximately 10 kilograms for Kingdom and gained around 10 kilograms for Golden Kamuy, adapting not only his weight but also his training methods, eating habits, and movement to suit each character.

Outside work, Yamazaki has shared stories about his love of meat dishes with garlic and ginger, making oyakodon at home, enjoying local food in Hokkaido, bringing his own pillow to filming locations, and relaxing through camping and visits to hot springs.

Drawing on interviews and official materials published between 2016 and 2026, this article explores Kento Yamazaki's beauty routine, skincare, haircare, fitness training, diet, hydration, sleep, and favorite ways to relax.

Kento Yamazaki's Beauty and Skincare Routine: Moisturizing, Haircare, and Scalp Massage

Facial Sheet Masks Before Bed and Fresh Pillowcases

One particularly informative look at Kento Yamazaki's beauty habits comes from an interview published by the Japanese beauty magazine MAQUIA in February 2024.

Asked about the things he pays attention to for his skin and general well-being, Yamazaki mentioned saunas, hot springs, hydration, moisturizing, and sleep.

One noteworthy part of his skincare routine is using a facial sheet mask before going to bed.

Even during busy filming schedules, he explained that he makes time for a sheet mask at night and pays attention to keeping his skin moisturized.

Film and television work can involve wearing makeup and spending long hours outdoors. His comments offer an interesting glimpse into how someone working in these environments also pays attention to his skin in everyday life.

Another revealing detail appeared in an interview with Hot Pepper Beauty Magazine on February 25, 2021.

Yamazaki explained that he liked to keep things that touched his skin as clean as possible and said that, at the time, he changed his pillowcase every day.

His attention extended beyond skincare products to the bedding that came into contact with his face while he slept.

In the same interview, he also discussed what he finds attractive in other people, emphasizing cleanliness and hairstyles that suit the individual.

Whether someone has short or long hair, he felt that a style complementing that particular person was what mattered most.

His daily pillowcase changes in 2021 and his use of facial sheet masks in 2024 were described at different points in his life. Both stories, however, show his interest in small, everyday approaches to personal care.

Simple Haircare and His Preferred Hair-Drying Technique

Kento Yamazaki has also shared specific details about how he cares for his hair.

According to his 2021 interview with Hot Pepper Beauty Magazine, he was using basic products such as shampoo, rinse, and conditioner at the time, and he made sure to dry his hair thoroughly with a hairdryer after bathing.

One detail he paid particular attention to was directing the airflow down over his hair from above.

Yamazaki explained that he had heard this was a good way to dry his hair and had incorporated the technique into his routine.

He also said that he rarely colored his hair outside the requirements of an acting role.

Although his work frequently involves different hairstyles, he appears to prefer a simple, natural approach in his private life.

Interestingly, the hairstyles he wears for his roles can influence what he feels like doing with his hair off camera.

When a character wears his fringe down, Yamazaki sometimes wants to push his hair back in his free time. When a role requires his hair to be styled back, he may feel like wearing it down instead.

Even something as ordinary as a hairstyle becomes a small way to enjoy the distinction between his professional image and his everyday self.

Scalp Massage in 2026 and His Longstanding Interest in Hot-and-Cold Bathing

In April 2026, Kento Yamazaki discussed scalp care during an interview connected to a shampoo campaign for the men's grooming brand uno.

He described a massage technique in which he makes a loose fist and uses the second joints of his fingers to move the scalp gently.

He explained that he was thinking about his hair in the years ahead and had incorporated scalp massage into his daily routine.

While his 2021 comments focused on basic haircare, his 2026 interview also highlighted an interest in looking after his scalp. Together, they suggest how his approach to grooming has evolved over time.

Yamazaki has also appeared in advertising for uno since 2023.

At an event connected to the brand that year, he said that he had been familiar with its products since his student days.

These comments were made in connection with advertising activities and should be understood in that context. Appearing in a campaign does not, by itself, establish that every featured product is part of his personal daily routine.

Another longstanding interest of Yamazaki's is bathing, particularly saunas, hot springs, and spending time in the bath at home.

In an official Koikeya interview released on October 30, 2024, he explained that he enjoyed a hot-and-cold bathing routine at home, soaking in warm bathwater before taking a cold shower.

He said he liked the refreshing feeling that followed warming up in the bath.

In an April 2026 interview with smart Web, he again talked about enjoying the contrast between warm and cold water.

His comments therefore establish that he had already adopted this style of bathing by at least 2024.

Sudden temperature changes and very hot baths can place stress on the body. His routine is presented here as a personal experience rather than a general recommendation. For everyday bathing, choosing a comfortable water temperature and paying attention to individual health and physical condition is important.

Kento Yamazaki's Fitness and Body Transformations for Kingdom and Golden Kamuy

Losing Around 10 Kilograms for Kingdom and Training as Shin Grows

One of the most important productions in Kento Yamazaki's physical development as an actor is the Kingdom film series.

Based on Yasuhisa Hara's popular manga, the live-action films feature Yamazaki as the protagonist Shin.

Shin grows up as a war orphan while pursuing his dream of becoming a great general.

To prepare for the first film, released in 2019, Yamazaki lost approximately 10 kilograms.

Reports from that period described how he significantly reduced his carbohydrate intake and ate foods such as chicken tenderloin and broccoli while preparing to portray Shin's lean physique as a young orphan.

At the same time, he undertook extensive action training to express the character's raw energy and instinctive fighting style.

His preparation began roughly six months before filming and included practicing fundamental sword movements, reacting to opponents, and learning how to evade attacks.

He also took horseback-riding lessons, expanding the range of movement he could bring to scenes set on the battlefield.

For Kingdom 2: Far and Away, released in 2022, Yamazaki changed his approach to physical preparation while continuing to portray the same character.

Where the first film called for the lean appearance of a young boy, the sequel presented a Shin who had spent more time training with a sword.

Yamazaki explained that he therefore placed greater emphasis on developing his arms.

He combined wooden-sword practice with weight training, preparing his body to suggest a character who had spent considerable time wielding a weapon.

Even though the protagonist remained the same, the demands of portraying him changed as the story progressed. Yamazaki wanted Shin's growth to be reflected in both his muscles and the way he moved.

The strict dietary restrictions used for the first film were part of a specific professional acting assignment. For everyday wellness, a balanced diet that supplies the nutrients the body needs remains the more appropriate approach.

Gaining Weight for Golden Kamuy with Weight Training Three to Four Days a Week

In contrast to the weight loss required for Kingdom, the 2024 film Golden Kamuy called for Yamazaki to build a considerably larger physique.

Based on Satoru Noda's manga, the film stars Yamazaki as Saichi Sugimoto.

Sugimoto is a former soldier who survived the Russo-Japanese War, a character known for his toughness, physical strength, and ability to endure the harsh natural environment of Hokkaido.

In a January 2024 interview with Cinema Today, Yamazaki explained that he had gained approximately 10 kilograms while doing weight training around three to four days a week.

In a separate MAQUIA interview in 2024, he described spending roughly six months building his physique for the part.

His meals included meat dishes such as steak, and he increased how frequently he ate.

In the January 2024 Cinema Today interview, he described eating four meals a day during that period.

Alongside building muscle, he also undertook military-style preparation and action training to develop the physical movements expected of a former soldier.

He slimmed down for Kingdom and built a larger physique for Golden Kamuy.

These contrasting experiences show how carefully he adjusts his preparation to match the physical requirements and movement of each character.

Morning Workouts in 2026 and His Preference for One-Hour Training Sessions

Kento Yamazaki has spoken not only about training for individual films but also about how he likes to exercise in everyday life.

In an official Koikeya interview published on October 30, 2024, he said he preferred to complete activities such as weight training and running in a session lasting around an hour.

He explained that setting a time limit and concentrating during that period suited him better than training for a long stretch.

In another interview related to a Koikeya commercial in July 2026, he revealed that he had recently been working out first thing after waking up.

Rather than following a fixed start time, he seemed to enjoy making exercise the first major activity of his day.

He explained that once he had completed his workout in the morning, he felt satisfied knowing he had already exercised, regardless of how the rest of the day unfolded.

He also spoke about enjoying the morning sunlight.

His 2024 comments focused on the length of his workouts, while his 2026 interview offered a closer look at when he liked to train.

For Yamazaki, exercise appears to serve a purpose beyond preparing his body for a role. It can also provide an enjoyable way to start the day and shift his state of mind.

Kento Yamazaki's Diet and Hydration: Meat Dishes, Home Cooking, and Protein

Garlic and Ginger Meat Dishes and the Food He Enjoys Cooking at Home

Among the foods Kento Yamazaki has mentioned enjoying are meat dishes flavored with garlic and ginger.

In a 2024 MAQUIA interview, he described these as foods he liked to eat when he wanted something hearty and satisfying.

He also talked about valuing a balanced diet that includes fish, vegetables, and rice.

Although his acting roles sometimes require adjustments to how much and what he eats, stories about his ordinary meals reveal a more familiar side of his personality.

In a May 2016 interview with ViVi, Yamazaki said he had recently started doing more housework and was enjoying cooking.

One dish he made at the time was oyakodon, a Japanese rice bowl topped with chicken and egg.

He was pleased with how well it turned out, although he admitted that facing the dishes afterward was rather less exciting.

It is an everyday experience that many home cooks can relate to.

In 2026, he also discussed his growing interest in cooking, expressing enthusiasm for meals he could enjoy outdoors while camping and for experimenting with dishes that involved making his own sauces or seasonings.

From making oyakodon in 2016 to taking an interest in outdoor cooking a decade later, Yamazaki has continued to find enjoyment not only in eating food but also in preparing it.

Hokkaido's Food Culture and the Dining Scenes in Golden Kamuy

One of the distinctive attractions of Golden Kamuy is its portrayal of Hokkaido's natural environment and rich food culture.

As Saichi Sugimoto and the young Ainu girl Asirpa travel through the story, they encounter a variety of local ingredients and traditional dishes.

Yamazaki also enjoyed Hokkaido specialties during filming, including seafood and jingisukan, the region's well-known grilled mutton dish.

In his 2024 MAQUIA interview, he recalled eating plenty of delicious local food during the filming period while working on gaining weight for the role.

Golden Kamuy also features many dining scenes that introduce viewers to aspects of Ainu food culture.

Chitatap is a preparation involving finely chopping ingredients such as meat or fish, while ohaw is a traditional soup made with ingredients that may include meat, fish, and vegetables.

The story also features dishes such as woodcock chitatap and ingredients including pukusa, a type of wild garlic.

These dishes and ingredients help bring the culture and setting of Hokkaido and the Ainu people into the world of the story.

When Sugimoto tastes unfamiliar food for the first time, the experience is conveyed not only through the ingredients but also through his surprise, enjoyment, and conversations with the people around him.

That combination of food, facial expressions, and relationships is part of what makes the dining scenes in Golden Kamuy memorable.

For Yamazaki, enjoying food in Hokkaido while portraying Sugimoto also provided an opportunity to immerse himself more deeply in the world of the production.

His Two-Liter Daily Water Goal and Approach to Protein

Kento Yamazaki has also spoken specifically about his approach to hydration.

In his 2021 interview with Hot Pepper Beauty Magazine, he revealed that he was aiming to drink two liters of water a day at the time.

He explained that he consciously tried to drink plenty of water as part of the attention he paid to his skin and body.

Hydration was also among the beauty and wellness habits he mentioned in his 2024 MAQUIA interview.

His specific goal in 2021, together with his later comments, shows that an interest in staying hydrated came up at different stages of his life.

However, the two-liter figure was Yamazaki's personal goal in 2021. Individual hydration needs vary according to body size, diet, physical activity, climate, and other circumstances, so an appropriate amount depends on each person's lifestyle.

In 2025, Yamazaki also appeared in advertising for SAVAS, a protein brand produced by the Japanese company Meiji.

During an interview connected to the campaign, he explained that when trying to build a larger physique, he paid attention to both strength training and his intake of protein and carbohydrates.

He was also quoted as saying that he drank SAVAS products in his everyday life.

These comments were made in the context of a promotional campaign. His own statements about product use are presented separately from the brand's advertising claims.

Because Kingdom and Golden Kamuy required very different physiques, Yamazaki adapted his eating habits to suit the demands of each part.

Both his carefully planned meals for acting roles and the foods he enjoys in daily life provide interesting insights into his relationship with food.

Kento Yamazaki's Sleep and Rest Habits: His Favorite Pillow and Ways to Unwind

A Comfortable Mattress and Pillow, Even When Filming Away from Home

Kento Yamazaki has shown an interest in creating a comfortable sleeping environment for many years.

In a May 2016 interview with ViVi, he identified his futon as one of his favorite places at home.

At the time, he explained that he used a mattress and pillow that suited his body.

Even then, he was paying attention to the bedding and surroundings that helped him feel comfortable at bedtime.

In February 2024, he told MAQUIA that he sometimes brought his own pillow when traveling to locations for extended filming periods.

Working on films and television dramas can involve spending long stretches of time away from home.

Taking a familiar pillow with him was one way of making those unfamiliar surroundings more comfortable.

He also shared another practical solution: when he did not bring his pillow, he would stack bath towels to adjust the height until it felt right.

In 2016, he had spoken about the mattress and pillow he liked at home. By 2024, he was sharing the small adjustments he made to his sleeping arrangements while filming on location.

Those details show the attention he gives to feeling comfortable at bedtime, even as his working environment changes.

Film shoots may involve early preparations and long periods of waiting, making his interest in a comfortable sleeping environment an especially revealing detail of his working life.

The Gym After Filming, Camping, Hot Springs, and an Interest in Meditation

Kento Yamazaki has a variety of interests that he enjoys after filming and on his days off.

He sometimes goes to the gym after work, and exercise appears to be one way he shifts his mood after a day on set.

In an official Koikeya interview in 2024, he described spending rainy days exercising indoors, watching films, or listening to music.

Physical activity and entertainment both have a place in the ways he likes to unwind.

He has also mentioned hot springs and camping among his favorite leisure activities.

In a July 2026 interview, he spoke about wanting to load camping equipment onto a motorcycle and head out into nature.

He expressed an interest in trying a solo camping trip as well as enjoying the outdoors with friends.

Whether he is watching a film, exercising at the gym, relaxing in a hot spring, or spending time outdoors, Yamazaki seems to enjoy having different ways to spend his free time depending on his mood and surroundings.

Kento Yamazaki's Early Life and Work Ethic: From Soccer to International Action Roles

From a Soccer-Loving Boy to an Internationally Recognized Action Star

Kento Yamazaki enjoyed sports from an early age.

Soccer was a particular passion during his school years.

Since beginning his acting career, he has challenged himself with many different forms of physical performance to meet the needs of his characters.

For Kingdom, he undertook lengthy action training and carefully planned physical preparation. For Golden Kamuy, he pursued the physique and movement of a former soldier.

In the Netflix series Alice in Borderland, he has also performed physically demanding scenes involving running, escaping, fighting, and survival.

Although his career has ranged from romance-focused productions to major action films, each new role brings different physical requirements, and he prepares accordingly.

He also makes time for interests that reflect his own personal tastes.

In a 2024 official Koikeya interview, Yamazaki revealed that he had loved vintage clothing since his teenage years.

When visiting other parts of Japan for filming or traveling abroad, he enjoys looking around vintage clothing stores and discovering unique pieces.

Training his body for his work and following his own sense of style in everyday life may seem like very different interests.

Yet both offer a glimpse of Yamazaki's enthusiasm for exploring the things that catch his attention.

Looking at Kento Yamazaki's beauty and wellness habits reveals two sides of his life: the disciplined physical preparation he undertakes for acting roles and the everyday routines he enjoys for skincare, relaxation, and personal comfort.

His interviews have touched on facial sheet masks before bed, moisturizing, changing pillowcases, drying his hair, scalp massage, saunas, hot springs, and carefully chosen sleeping arrangements.

Professionally, he has also transformed his physique for major film roles, losing approximately 10 kilograms for Kingdom and gaining around 10 kilograms for Golden Kamuy.

In 2026, he spoke about enjoying morning workouts and finding satisfaction in starting the day with physical activity.

At home, he has made oyakodon, taken an interest in convenient cooking gadgets, and spent his free time enjoying films, camping, and hot springs.

These personal stories reveal both the determination he brings to his work and his relaxed enjoyment of ordinary life.

As his career and lifestyle change, he continues to explore habits and activities that feel right for him.

Through his comments on beauty, fitness, food, and rest, Yamazaki offers a collection of engaging, down-to-earth ideas about taking an interest in one's body and finding enjoyment in everyday routines.
