Kento Nakajima Beauty & Wellness: Skincare, Perfume, Fitness & Sleep

Known affectionately as "Kenty," Kento Nakajima has built a career as an idol, actor, and solo music artist. His polished fashion sense and charismatic stage performances are familiar to fans, but his interviews reveal another side of his personality: a genuine interest in skincare, fragrance, fitness, food, sleep, and everyday wellness.

Since 2020, Nakajima has served as an image ambassador for the Japanese skincare brand PERFECT ONE. As he entered his thirties, he also began speaking about his appreciation for more natural fashion and his evolving understanding of personal beauty. Exercise and sleep are two habits he has specifically identified as important to his beauty and wellness routine.

His approach to physical fitness is equally interesting. In November 2023, Nakajima began an intensive training period for a television drama, visiting the gym six times a week and paying closer attention to his food choices. In 2025, he prepared for his first solo concerts with extensive rehearsals, bringing the same dedication to his work as both an actor and performer.

Yet he is also an enthusiastic food lover. Carbonara is a particular favorite, and he has enjoyed exploring different versions of the dish while spending time in Italy. Meals prepared by friends and memorable food experiences on filming locations are another important part of his life.

In 2026, Nakajima took his passion for fragrance a step further by launching KENTY FRAGRANCE, a creative project that transforms the stories and emotions behind his songs into scents.

Drawing on interviews and official announcements published between 2020 and 2026, this article explores Kento Nakajima's beauty philosophy, skincare interests, favorite fragrances, fitness training, eating habits, sleep, bathing routines, family stories, and relationship with his fans.

1. Kento Nakajima's Beauty and Skincare Philosophy

Skincare, Self-Expression, and His Approach to Natural Beauty

For Kento Nakajima, beauty is connected to more than skincare alone. Over the years, he has spoken about how personal values, everyday habits, and a sense of individuality contribute to his understanding of beauty.

In a June 2025 interview with the Japanese beauty magazine BITEKI, Nakajima described a beautiful person as someone who lives authentically and stays true to themselves.

After moving from group activities into a new chapter as a solo artist, he continued to explore what it means to create an identity that reflects his own interests and artistic vision.

Nakajima has also spent many years representing a skincare brand and appearing in beauty-related media, giving him opportunities to discuss his attitudes toward appearance and self-care.

On stage, he embraces striking costumes, carefully styled hair, and expressive makeup. In his everyday life, he also appreciates relaxed and understated fashion.

His interest in personal care extends beyond appearance to exercise, sleep, food, and bathing.

Rather than following one fixed image of beauty, Nakajima appears to value the freedom to enjoy different styles while developing his own sense of identity.

PERFECT ONE and His More Natural Style in His Thirties

Since 2020, Nakajima has served as an image ambassador for PERFECT ONE, a skincare brand developed by Shin Nihon Seiyaku, also known as Shin Nihon Pharmaceutical.

The brand offers skincare products including all-in-one formulations, and Nakajima has appeared in television commercials and promotional campaigns over several years.

In a September 2024 interview connected to the brand, he chose the word "natural" to describe a quality he had come to appreciate about himself after turning thirty.

He explained that he previously enjoyed wearing multiple accessories, including chains, but had become increasingly interested in simpler outfits.

Tank tops, tracksuits, sweatshirts, and combinations of casual sportswear with denim were among the styles he discussed.

Although his stage outfits are often glamorous, his everyday fashion reflects an appreciation for comfortable, understated clothing.

The same interview introduced an interesting perspective on time management.

In connection with PERFECT ONE's all-in-one skincare products, Nakajima spoke about moving beyond the idea of simply saving time toward creating time for meaningful experiences.

The Japanese expression he used was "jisan," or the idea of generating time, rather than merely "jitan," meaning time-saving.

His philosophy was to use the time made available through everyday routines for new challenges and activities he genuinely enjoys.

In October 2025, he appeared in the brand's "Doors to the World: Milan and Paris" commercial. In June 2026, he starred in the "Red Carpet" campaign celebrating PERFECT ONE's twentieth anniversary.

For the 2026 commercial, Nakajima wore a striking red suit and performed a polished dance sequence against a red-carpet setting.

He also expressed his appreciation for his longstanding relationship with the brand.

His PERFECT ONE appearances are part of his official promotional work. They are presented separately from any specific products he has personally confirmed using in his private routine.

Exercise and Sleep: Two Habits He Values for Beauty

In a June 2026 interview released alongside a new PERFECT ONE commercial, Nakajima identified exercise and sleep as two things he considers important for beauty.

He associates physical activity and sufficient rest with maintaining his everyday condition, especially while balancing different creative and professional responsibilities.

Sleep was also a subject he highlighted in an interview connected to the same brand in 2020, suggesting that rest has remained a consistent priority in his approach to personal care.

His schedule has included acting, recording music, live performances, and promotional appearances. Across these activities, he has continued to speak about making room for movement and rest.

For Nakajima, beauty appears closely connected to living in a way that supports his work while allowing him to enjoy his personal interests.

2. Kento Nakajima's Perfume and Fragrance Passion

KENTY FRAGRANCE: Turning His Music into Scents

Fragrance is one of the most distinctive aspects of Kento Nakajima's personal style and creative interests.

In 2026, he launched KENTY FRAGRANCE, a project that interprets the emotions and stories behind his music through perfume.

Nakajima had been considering the idea of combining music and fragrance for several years. He was personally involved in developing the concept and shaping how each scent would reflect its corresponding song.

The first collection was released on March 14, 2026, featuring fragrances inspired by three songs: "CANDY ~Can U be my BABY~," "SHE IS...LOVE," and "IDOLIC."

Each fragrance was designed to offer another way of experiencing the atmosphere and emotional story of a piece of music.

A pop-up event was also held in Harajuku, Tokyo, allowing visitors to explore the relationship between the songs and their fragrances.

The second collection followed in June 2026, featuring scents inspired by "Hey!! Summer Honey," "jealous," and "ROSSO."

These fragrances brought together themes of summer, romantic emotions, and personal memories, with each scent connected to a different musical story.

A third collection arrived on September 7, 2026.

This release drew inspiration from three more songs: "Scene29," "Jasmine Tea," and "Black Cinderella."

"Scene29" was written with the feeling of offering a gift to his twenty-nine-year-old self. The song reflects appreciation for his own journey and gratitude toward the people who have shared it with him.

"Jasmine Tea" grew from a desire to be gentle with his own feelings. Its story was translated into a fragrance inspired by the soft character of jasmine.

"Black Cinderella" explores the sophisticated adult world Nakajima imagined when he was twenty years old.

Creating a fragrance inspired by that song allowed him to revisit an earlier vision of adulthood from the perspective of his thirties.

Across the three collections, KENTY FRAGRANCE connects his past music with his present creative identity.

The song titles mentioned here are the musical inspirations behind the fragrances. Official retail product names may use different wording and should be distinguished from the original song titles.

In a September 2026 interview with ViVi, Nakajima also discussed his involvement in planning music releases, fragrances, and concert merchandise.

He explained that he enjoys developing ideas, examining details, and turning concepts into finished projects.

At the same time, he values his own intuition when making creative decisions.

KENTY FRAGRANCE brings these interests together: music, perfume, storytelling, and his enthusiasm for developing something personal from an original idea.

Why He Stopped Wearing Perfume for My Dearest, Like a Cherry Blossom

One memorable example of Nakajima's relationship with fragrance comes from the 2022 Netflix film My Dearest, Like a Cherry Blossom, known in Japanese as Sakura no Yona Boku no Koibito.

In the film, he plays Haruto Asakura, a young man who dreams of becoming a photographer.

At a premiere event in March 2022, Nakajima revealed that he had temporarily stopped wearing his usual perfume during filming.

He wanted to portray his character with an authentic, everyday quality and felt that changing even a familiar personal habit could help him approach the role.

For someone who enjoys fragrance as part of daily life, this was a notable choice.

In 2022, he adjusted his perfume routine to support an acting performance. Four years later, he developed his own fragrance project as a solo musician.

The two experiences show how scent has become part of Nakajima's artistic expression as well as his personal sense of style.

3. Kento Nakajima's Fitness, Gym Training, and Dance

Training Six Days a Week for Living no Matsunaga-san

One of the clearest examples of Nakajima's commitment to physical preparation comes from an interview published by Mezamashi Media on January 5, 2024.

At the time, he was filming the television drama Living no Matsunaga-san, also known as Living with Matsunaga-san.

He played Jun Matsunaga, a twenty-nine-year-old designer living in a shared house.

The role included scenes that revealed his upper body, prompting him to pay particularly close attention to his physical condition.

According to Nakajima, he began a focused training period in November 2023 and was visiting the gym six times a week.

He even recalled heading to the gym after a meal with work colleagues, continuing his training despite an already busy schedule.

Looking back, he joked about how surprised he was by his own enthusiasm.

Preparing for the drama also encouraged him to think more carefully about what he ate between filming sessions.

As he approached his thirtieth birthday in 2024, Nakajima spoke about wanting to continue developing himself physically for both acting and music.

The six-day-a-week gym schedule describes this particularly intensive period of preparation in late 2023, rather than a permanent training schedule.

Solo Concert Rehearsals and Expressive Dance, Right Down to His Fingertips

Live performance is another major reason Nakajima pays close attention to his physical preparation.

His first solo concerts in 2025 gave him an opportunity to combine his years of experience as an idol with a more personal artistic vision.

In a February 2025 interview with GINGER, he discussed the preparation involved in creating his first solo stage production.

He spent an extended period rehearsing with fellow performers, refining the choreography, pacing, and details of the show.

In a 2026 Billboard JAPAN interview, Nakajima reflected on his experience dancing after developing more muscle.

He discussed becoming more conscious of how his body moved and how to control its weight during choreography.

He has also considered how to adjust his approach to training depending on his activities and physical condition at a particular time.

His attention to movement extends beyond major dance sequences.

For his song "Fiction Love," Nakajima created choreography incorporating detailed finger movements.

He described gestures performed near his face that form letters with his fingers, and discussed creating movements that could also showcase nail styling.

This attention to hand positions, costume details, and styling demonstrates how carefully he considers the visual presentation of a song.

For Nakajima, music, fashion, beauty, and dance are connected parts of one creative world.

He also discussed plans to incorporate different languages and performance ideas during his 2026 Asian tour, hoping to communicate directly with audiences in each destination.

4. Kento Nakajima's Diet, Protein, and Favorite Foods

Eating for His Roles: Fish Bento, Protein, and Thoughtful Food Choices

Nakajima's eating habits have changed at different stages of his career, particularly when preparing for demanding acting roles and live performances.

In a January 2024 interview about Living no Matsunaga-san, he explained that the intensive gym training he began in November 2023 had encouraged him to reconsider some of his meals on set.

He previously enjoyed choosing foods such as hamburg steak and steak, along with snacks and fruit. During this training period, he increasingly selected meals such as grilled mackerel bento and protein-containing foods.

He also paid attention to how much he ate while working, making choices that suited the demands of filming.

As he prepared for his first solo concerts in 2025, he continued to think about the relationship between food and physical performance.

In a July 2025 CLASSY. interview, Nakajima explained that he had become more conscious of choosing dishes and foods containing protein since entering his thirties.

He also revealed that he enjoys sweets and sometimes chooses protein-enriched bagels.

In an October 2025 interview associated with PERFECT ONE, he mentioned frequently drinking protein shakes while working.

These accounts show how his interest in food has developed alongside acting, dance, and solo music activities.

In a July 2025 BITEKI feature, Nakajima was also asked to offer advice to a reader who wanted to reconsider their sweetened drink choices.

He suggested water or tea as alternatives, reflecting his interest in everyday food and beverage decisions.

That suggestion was advice offered to a reader rather than a description of a fixed personal drinking routine.

His approach to food combines attention to the demands of his work with an appreciation for meals he genuinely enjoys.

His Love of Carbonara: Home Cooking and Food Experiences in Italy

One of Nakajima's best-known favorite dishes is carbonara.

In a May 2022 interview with MAQUIA, he described how he likes to prepare the dish himself.

His preferred version includes plenty of freshly grated Parmigiano Reggiano, creating a rich and satisfying flavor.

Preparing food according to his own tastes is another way he enjoys cooking.

While staying in Italy to film the international drama Concordia, Nakajima also had opportunities to explore authentic Italian carbonara at local restaurants.

He enjoyed trying different versions of the dish and experiencing Italian food culture through a familiar favorite.

In another food-related interview associated with a Bulgari Valentine's Day project in 2024, he discussed a chocolate combining pistachio and fennel.

As a fan of pistachio, he appreciated the dessert's rich and distinctive flavor.

Whether cooking for himself, dining while traveling, or trying an unusual sweet treat, Nakajima enjoys discovering food that matches his personal preferences.

A Food Lifestyle Advisor Who Still Enjoys His Favorite Comfort Foods

Another interesting detail about Nakajima is that he holds a qualification as a food lifestyle advisor in Japan.

In a 2024 interview, he discussed his interest in food and the way he adjusts his choices depending on his work and everyday life.

During physically demanding projects, he may pay closer attention to his meals. At other times, he enjoys eating favorite foods simply for pleasure.

In a 2025 CLASSY. interview, he shared amusing stories about enjoying generous servings of dishes such as fried rice and xiaolongbao while traveling.

Food has also played a part in his friendships.

His friend Daiki Shigeoka of the group WEST. once invited him home and prepared a hot-pot dish featuring pork and lettuce.

The meal was a thoughtful gesture from a close friend, and Nakajima remembered the experience warmly.

In an interview connected to a 2026 screen production, Nakajima also spoke enthusiastically about meals provided on set, including warm rice, miso soup, and a variety of prepared dishes.

He has even recorded memorable food experiences on Instagram, showing how much he enjoys meals as part of the atmosphere and memories of a project.

From carefully chosen workday meals to home-cooked food shared with friends, eating is both a practical consideration and a source of enjoyment in Nakajima's life.

5. Kento Nakajima's Sleep, Bathing, and Relaxation Habits

Slow Mornings, Music Production, and Time at Home

Although Nakajima emphasizes the importance of sleep for beauty, his descriptions of his days off reveal a more relaxed and personal side of his lifestyle.

In an August 2023 interview with Ray, he admitted that waking up in the morning was not always easy for him.

He enjoys spending time in bed on his days off and appreciates being able to relax at home.

His home also includes a space dedicated to composing music, equipped with tools for songwriting and production.

He sometimes collaborates online with musician friends and can become so absorbed in creating songs that he loses track of time.

It is a distinctly artistic way of spending a day away from public appearances and live performances.

He has also spoken about admiring the idea of a more structured morning routine and imagining how he would like to spend an ideal day off.

These reflections from 2023 offer a glimpse into his personal schedule, while his later comments in 2026 show that sleep remains an important consideration in his approach to beauty and wellness.

Returning to the Bathtub and Using Tennis Balls for Self-Care

Nakajima has also spoken about bathing and stretching in an interview published by BITEKI in June 2025.

He recalled a busy period when he often relied on quick showers and began noticing stiffness in his body.

He subsequently made more time to soak in the bathtub and became more conscious of stretching.

Nakajima described noticing changes in how his body and skin felt as he adjusted these habits.

He also discussed using tennis balls as part of his personal body-care routine.

The idea reflects his interest in paying attention to his physical condition and making use of familiar items in everyday life.

During the interview, he also mentioned an idea involving placing a ball between a chair and the back for people who spend extended periods sitting.

These descriptions reflect Nakajima's personal experiences. Anyone considering pressure-based self-massage should take their own comfort and physical condition into account.

For Nakajima, bathing and stretching are among the small routines that help him make time to check in with his body during busy periods.

6. Kento Nakajima's Personality, Family, and Relationship with Fans

Lessons from His Family and a Decade of Connecting Through KenTeaTime

Family stories offer another perspective on Kento Nakajima's personality.

During an October 2023 appearance on the television program Tetsuko no Heya, he explained that his mother had taught him manners and consideration for others from an early age.

He learned everyday gestures such as opening the car door for his mother and allowing another person to go first.

Those childhood lessons are closely connected to the courteous and attentive personality that fans often associate with him.

In a January 2024 television appearance on Poka Poka, Nakajima also recalled visiting Tokyo Disneyland with both of his parents.

He enjoyed spending time together as a family and even took photographs of his parents walking side by side.

Gift-giving is another way he enjoys expressing consideration for others.

In a 2022 MAQUIA interview, he mentioned giving bouquets of roses to people he wanted to become closer to and bringing home numerous souvenirs from his travels.

These small gestures reveal how much thought he puts into making other people happy.

Nakajima has also placed great importance on maintaining a close connection with his fans.

In a June 2026 PERFECT ONE interview, he revealed that he had been updating his official blog, KenTeaTime, every day for approximately ten years.

He explained that continuing to share his thoughts, even during busy periods, had become a source of personal confidence.

In a 2022 MAQUIA interview, he reflected on a period when he was performing at Tokyo's Imperial Theatre.

There were days when he felt disappointed with his own performance and wondered whether he had delivered what he intended.

Reading letters from fans after the shows helped him discover how audiences sometimes appreciated moments he had judged differently himself.

The experience taught him that his own expectations and the feelings of the audience could offer different perspectives on the same performance.

He also spoke about gradually learning to appreciate himself more through the encouragement he received.

In a 2025 CLASSY. interview, Nakajima discussed wanting to value his own path in his thirties rather than constantly comparing his life with other people's experiences.

As a solo artist, he aims to express his own ideas while remaining open to the contributions of his creative team.

His career expanded further in 2026 with an Asian tour, allowing him to share his music and performances with audiences beyond Japan.

Throughout these different stages, Nakajima has continued to value relationships with his family, fans, fellow performers, and the people involved in bringing his projects to life.

Conclusion: What Kento Nakajima's Beauty and Wellness Habits Reveal

One of the most memorable qualities in Kento Nakajima's approach to beauty and wellness is his willingness to take the things he loves seriously and turn his interests into creative experiences.

He has committed himself to intensive physical preparation for acting roles, spent long periods developing live performances, and explored the details of how music can be expressed through movement and personal style.

At the same time, he enjoys favorite meals, makes room for music production at home, and values moments shared with friends and family.

Launching a fragrance project inspired by his own songs is another example of how he turns a long-held idea into something tangible.

His family's lessons about courtesy, the encouragement he has received from fans, and the years spent sharing his thoughts through KenTeaTime also reveal the thoughtful person behind his glamorous stage presence.

As Nakajima continues to develop his own creative identity, his interests in beauty, music, fragrance, performance, and personal connection remain closely intertwined.
