Yoji Iwase Beauty & Wellness | Skincare, Diet, Fitness & Sleep

With his striking features, fresh appearance and ability to convey different emotions through subtle expressions, Japanese actor Yoji Iwase has attracted growing attention for his performances on screen.

Born on January 6, 2004, in Hyogo Prefecture, Japan, Iwase is 178 cm tall. He gained recognition through the 2023 drama Mr. Hiiragi's Homeroom follow-up era? No—through The Best Teacher: One Year Later, I Was Killed by a Student (Saiko no Kyoshi) and the 2024 series New Airport Occupation (Shin Kuko Senkyo). Later that year, he took on his first leading role in the television drama Takara's Treasure (Takara no Vidro).

In 2025, he appeared in the film A Girl & Her Guard Dog (Ojo to Banken-kun) and the drama Kitakun Is Too Cute to Handle, So Three of Us Decided to Share Him (Kita-kun ga Kawaisugite Te ni Amaru node, Sannin de Share Suru Koto ni Shimashita). In the latter, he played Makina Kita, a young man with a mysterious charm that naturally draws people toward him.

His career continued to expand in 2026 with DREAM STAGE, in which he portrayed a K-pop idol, the café-set drama Kuroema, and Mou Papa!, among other projects.

Away from acting, Iwase has a genuine enthusiasm for beauty and skincare. He has spoken in detail about using face masks in the morning and evening, facial serums, eye treatments, facial steamers and haircare routines tailored to his hair texture.

He has also shared his experiences with protein drinks and vitamin supplements, his interest in homemade smoothies and cooking, and his daily habits involving cold showers, stretching, warm water and herbal tea.

Drawing on Iwase's own interviews, this article explores his beauty and wellness habits, skincare products, diet, fitness, sleep and bathing routines. It also introduces his career, family relationships, friendship with fellow actor Ryubi Miyase and some entertaining stories that reveal a side of him beyond the screen.

1. Yoji Iwase's Beauty and Skincare Routine: Face Masks, Eye Serum and Haircare

Morning and Evening Face Masks and His Detailed Skincare Routine

One of the clearest examples of Yoji Iwase's interest in beauty comes from an interview with mini magazine in 2024.

At the time, he explained that he used face masks both in the morning and at night. One of his favourites was VT COSMETICS' CICA Daily Soothing Mask, which he kept in the refrigerator and used almost every day.

Even more interesting was how precisely he described the order of his skincare products.

He began with DECORTÉ Liposome Advanced Repair Serum, followed by a spray-type facial toner purchased at a drugstore. Next came a sheet mask, a DECORTÉ face cream and an eye serum.

For the eye area, he used DECORTÉ Liposome Advanced Repair Eye Serum. He also adjusted his routine depending on the time of day, explaining that he skipped the cream in the morning.

In another 2024 interview with VOCE, he discussed caring for his skin after cleansing and protecting it from the sun with hats and sunscreen.

Iwase described his ideal skin as smooth and soft to the touch. He said that feeling happy with the texture of his own skin could brighten his mood.

He also enjoys researching Korean beauty trends on social media and trying skincare products that catch his attention.

In a September 2026 interview with smart, Iwase revealed that he also regularly uses a facial steamer alongside face masks.

In the same interview, he mentioned taking vitamins every day, showing that he pays attention to both his external beauty routine and his everyday diet.

From his detailed face-mask routine in 2024 to his use of a facial steamer in 2026, Iwase's interviews show an ongoing interest in discovering skincare products and incorporating them into his lifestyle.

The product names and routines described here reflect what Iwase personally shared at the time of each interview.

Skincare Advice from His Mother and Haircare Tailored to His Hair Texture

In an October 2026 interview with the beauty and hairstyling magazine PREPPY, Iwase revealed that his mother knows a great deal about cosmetics and often introduces him to skincare products.

He enjoys trying products she recommends and said he had recently begun using a customised facial lotion.

According to Iwase, the lotion feels suitable for his skin, and he combines it with other products in his routine.

The fact that he exchanges beauty tips with his mother adds a warm, personal dimension to his enthusiasm for skincare.

In the same interview, he also discussed an unexpected challenge involving his hair.

Although his hair is naturally smooth, it grows fairly straight out from the scalp. As it gets longer, the sides tend to stick out, making his hairstyle more difficult to manage.

Even with an undercut, he notices extra volume around the sides, so he uses a down perm to create a shape he prefers.

He also said that he uses a hair treatment every day as part of his regular haircare routine.

While audiences see Iwase in many different hairstyles for his acting roles, his everyday haircare includes practical choices based on his own hair texture.

He has also explained that beginning work as an actor and model was one of the reasons he became more interested in beauty.

What started as an interest connected to his career has become something he enjoys through choosing cosmetics, sharing recommendations with his mother and taking time for daily self-care.

Lip Care, Body Scrubs and His Love of Fragrance

Iwase's beauty interests extend to lip care, body care and selecting fragrances to suit different occasions.

In his 2024 interview with mini, he mentioned using IPSA The Time R Lip Essence and d program Lip Moist Essence N.

For body care, he had purchased Dove Creamy Scrub Sakura & Musk after discovering it on social media. He said he used it approximately two or three times a week and enjoyed how his skin felt afterward.

Another area of particular interest is fragrance.

In 2024, Iwase told mini that he selected different perfumes for summer and winter.

During summer, he preferred gentle fragrances such as Santa Maria Novella Acqua di Colonia Pot Pourri. In winter, he sometimes chose sweeter and more subdued scents.

He also identified Jo Malone London's English Oak & Hazelnut Cologne as one of his favourites.

In another interview with GINGER that year, he explained that his choice of fragrance could depend on his clothes, the season and even whether it was morning or evening.

He might combine a stronger fragrance with a stylish outfit, while choosing something softer for casual clothing. He also enjoys wearing his favourite perfume before going to bed.

When discussing romantic attraction, he mentioned that a pleasant fragrance was one of the qualities he noticed in another person.

For Iwase, perfume is another part of personal style, with each scent selected to complement his clothes, the season and his mood.

2. Yoji Iwase's Diet and Wellness: Protein, Vitamin Supplements and Homemade Food

Protein Drinks, Vitamin Supplements and Homemade Smoothies

Iwase also takes an interest in what he eats and drinks.

In his 2024 interview with mini, he said that during a period of regular training, he drank protein shakes between breakfast, lunch and dinner, as well as before going to bed.

He also paid attention to protein in his meals while combining his diet with exercise at the gym.

Because he found it difficult to eat large amounts of food in one sitting, he also incorporated liquid vitamin supplements such as Lypo-C into his routine at the time.

In a 2025 interview, he spoke about being mindful of vegetables and dietary fibre and choosing foods such as soybeans as part of his protein intake.

In September 2026, he told smart that he was taking vitamins daily. This was a separate statement from his 2024 comments about Lypo-C, and the interview did not establish that he was still using the same product.

Another favourite appeared in May 2026: a homemade strawberry and banana smoothie.

His recipe is simple. He cuts strawberries and bananas into pieces, freezes them and then blends the frozen fruit.

His particular preference is to avoid adding water. With banana in the mixture, the result has a thick, creamy texture that he likens to gelato.

On the day of the interview, he had left home too early to prepare one. He said he was looking forward to returning home and making a smoothie afterward.

His diet-related interviews reveal both an interest in supporting his training through everyday food choices and a genuine enjoyment of preparing things he likes to eat.

His comments about protein drinks, vitamin supplements and food reflect personal routines at the time of each interview.

His Grandmother's Bolognese Recipe and Late-Night Homemade Caramel

One of the most enjoyable discoveries about Yoji Iwase is just how much he likes cooking.

In October 2024, during an interview alongside his Snowdrop's First Love co-star Ryubi Miyase, Iwase introduced a bolognese pasta recipe taught to him by his grandmother.

The method is surprisingly elaborate.

He begins by shaping the meat into a large patty roughly the size of his palm, then places it in a pot. He adds red wine and lets the meat simmer slowly for approximately two hours.

Once the liquid has reduced, he breaks up the meat and combines the sauce with cooked pasta.

The unusual step of cooking the meat as one large patty caught Miyase's attention. His co-star was intrigued enough to say that he wanted to try making it himself.

For Iwase, it is also a recipe with family history, passed down from his grandmother and now part of his own cooking repertoire.

But there is another unexpected side to his enthusiasm for the kitchen: making fresh caramel late at night.

In a June 2026 interview with Mezamashi Media, Iwase revealed that he loves sweets so much that he sometimes starts making soft caramel in the middle of the night simply because he feels like eating it.

When asked to give his private self a nickname, he described himself as an extremely playful, energetic guy.

In October 2026, he told GINGER about making sweets in the kitchen at night with just the kitchen light on.

He admitted that while preparing them, he is often thinking about how soon he can eat them and whether there is any way to shorten the time needed for the caramel to set.

His cooking extends well beyond desserts.

In 2026, he also described preparing a seasonal pesto-style pasta with rapeseed blossoms, bamboo shoots and firefly squid.

He blended rapeseed blossoms and shiso leaves, added anchovies to the sauce, and combined it with bamboo shoots and carefully prepared firefly squid.

From his grandmother's bolognese to seasonal pasta and spontaneous late-night desserts, cooking gives Iwase a chance to enjoy favourite flavours and make something with his own hands.

3. Yoji Iwase's Fitness Routine: Gym Training and Physical Preparation for Acting Roles

Weight Training, Running and His Background in Sports

Training is listed as one of Iwase's hobbies in his official agency profile.

In a 2024 interview with anan, he explained that he had been doing weight training and running at the gym while also paying attention to his meals.

At first, he went to the gym approximately four times a week. He later settled into a routine of one or two visits a week.

In another 2024 interview with Wellchill, he said that he particularly enjoyed training his upper body.

During that period, he sometimes spent about an hour exercising at the gym, followed by another hour dedicated to caring for his body.

Iwase also has experience with a wide variety of sports beyond gym workouts.

His official profile lists basketball, swimming, skateboarding and karate among his special skills.

From ball sports and swimming to martial arts and board sports, he has explored several different ways of staying active.

Watching baseball at Koshien Stadium is another of his hobbies. He enjoys watching sports as well as taking part in them.

His interviews describe a lifestyle in which time spent training is balanced with paying attention to how his body feels and making time for physical care.

Losing Approximately 10 Kilograms for DREAM STAGE and Researching Every Detail of a Role

In 2026, Iwase also discussed how he adjusted his physique for an acting role.

For the drama DREAM STAGE, he portrayed Ryo, the centre of the K-pop group TORINNER. In an October 2026 interview with PREPPY, he revealed that he had lost approximately 10 kilograms in preparation for the role.

He subsequently returned to his previous weight and spoke about a plan to gain approximately 10 kilograms during 2027 for another stage of his work.

He also mentioned wanting to approach the process carefully, paying attention to the physical demands of increasing his food intake.

While his 2024 interviews focused on regular gym training and running, his 2026 comments described the different demands of preparing his body for a particular character.

His attention to a role extends beyond weight and physical appearance.

In the 2024 drama Takara's Treasure, he played Takara Shiga, a reserved university student. Iwase explained that he carefully considered the character's posture, movements and expressions around the eyes.

He found it particularly challenging to communicate emotions through slightly lowered eyes and subtle shifts in expression.

He also thought carefully about how Takara's calm manner should contrast with the character played by co-star Eito Konishi.

In the 2026 drama Kuroema, Iwase played Simon, a traditional café manager. He studied even small details, including how to move his fingers while preparing a parfait, how deeply to bow to customers and what tone of voice to use.

For Mou Papa!, he spoke to friends who had experienced job hunting to better understand the university student he was portraying.

Whether preparing his physique, choosing an expression or imagining a character's everyday life, Iwase approaches each role by building a detailed picture of the person he wants to portray.

The weight changes discussed here were part of Iwase's specific preparation for acting roles and reflect his professional experiences.

4. Cold Showers, Sleep and Bathing: Yoji Iwase's Evening Routine and Herbal Tea

His Morning Cold-Shower Habit, Maintained for Approximately Three Years

One of the most distinctive habits Iwase has described is taking a cold shower in the morning.

At an event in March 2026, he revealed that he had maintained the routine for approximately three years.

He said that taking a cold shower before work makes him feel more awake and helps him mentally switch into work mode.

According to Iwase, he keeps up the routine even during winter, making it a familiar part of his mornings.

He had also spoken about taking cold morning showers in a 2024 VOCE interview, providing another account of the habit at an earlier point in his career.

At other times, particularly after a long period of filming, he enjoys spending time soaking in the bath.

He has said that he sometimes uses scented bath essences to make the experience more enjoyable.

Cold showers form part of his morning transition into work, while a warm, fragrant bath provides a different experience when he has more time to unwind.

Sudden exposure to cold water can place stress on the body, particularly for people with certain health conditions. Iwase's cold-shower routine is presented here as his personal experience.

Twenty Minutes of Stretching After Bathing, Followed by Warm Water or Herbal Tea

Iwase shared more details of his evening routine in an October 2026 interview with PREPPY.

When he feels particularly tired, he prioritises getting enough sleep.

Before going to bed, he spends around 20 minutes stretching after taking a bath.

After stretching, he enjoys something warm to drink.

Although he likes hot milk, he considers how his stomach is feeling and sometimes chooses warm water or caffeine-free tea instead.

Herbal tea is one of the drinks he specifically recommended in the interview.

Taking time to stretch after a bath and then enjoying a warm drink gives his evenings a quieter rhythm, contrasting with the cold shower he prefers in the morning.

At a separate event in March 2026, he also discussed stretching before bed, saying that he personally noticed a difference in how his body felt the following morning when he had made time for it.

Warm water and herbal tea are included here as drinks that Iwase personally enjoys according to his preferences and how he feels.

His Eight-Hour Sleep Goal, Classical Music and Favourite Ways to Relax

Iwase has also spoken about his personal preferences when it comes to sleep.

In a 2024 interview with anan, he said that he tried to get around eight hours of sleep whenever possible.

At the time, he described himself as someone who could fall asleep and wake up fairly easily. He also enjoyed arranging four pillows and two cushions on his bed to give it a hotel-like atmosphere.

In his 2026 PREPPY interview, he said that although he slept deeply, getting out of bed in the morning had become a little more difficult.

His descriptions of waking up differed between interviews, while his interest in making time for sleep remained consistent.

Iwase also enjoys listening to music.

In a 2024 interview with Wellchill, he spoke about relaxing in bed while listening to classical piano music performed by Nobuyuki Tsujii.

In 2025, he described a home decorated mainly in white and his enjoyment of stretching out on a king-size bed.

In 2026, he told PREPPY that shopping was one of his favourite ways to change his mood. He also enjoys going out for meals with his manager and spending time talking about a variety of things.

In a May 2026 interview, he expressed a desire to visit the sea.

He mentioned destinations such as Bali and Yoronjima, a Japanese island known for its beautiful coastline, as well as Kamakura, where he would enjoy walking around town and trying different foods.

Whether he is listening to classical music at home, browsing shops, sharing a meal or planning a coastal getaway, Iwase finds enjoyment in a variety of experiences away from filming.

5. Career, Family and Friendships: Getting to Know Yoji Iwase Beyond the Screen

His Early Social Media Attention and Friendship with Ryubi Miyase

One of the events that first brought Yoji Iwase to wider attention was the circulation of photos of him during his school years on social media.

He was subsequently approached by a talent agency and began pursuing acting.

Following his appearance in the 2023 drama The Best Teacher: One Year Later, I Was Killed by a Student, he gained further recognition in 2024 through New Airport Occupation and Takara's Treasure.

In 2025, he played Makina Kita in Kitakun Is Too Cute to Handle, So Three of Us Decided to Share Him, adding another memorable character to his growing acting career.

One friendship that offers a particularly entertaining glimpse of Iwase's personality is his relationship with fellow actor Ryubi Miyase.

The two first worked together in the 2024 drama Snowdrop's First Love. According to Iwase, however, they had already known each other for approximately four years.

They are close enough to call each other by their given names, and Iwase has described Miyase as a dependable friend who offers advice when he is uncertain about his acting.

Miyase, in turn, spoke highly of how Iwase managed to remain cheerful and smiling even during demanding periods of filming.

Yet Miyase also recalled seeing a very different side of his friend one day.

Iwase had fallen fast asleep in a chair in the shared makeup room.

When Miyase brought up the incident in their interview, Iwase seemed surprised that his friend had witnessed it.

Miyase also described him as having an innocent, childlike side. Iwase laughed and explained that, being from the Kansai region, he naturally tends to make jokes.

The exchange showed a relaxed, playful personality that contrasts with some of the cool and reserved characters he plays on screen.

His Daily Messages to His Grandmother and Habits Learned from Family

Family is another important part of the person Iwase describes in interviews.

In October 2026, he told GINGER that his grandmother was someone he contacted almost every day.

He sends short messages in the morning to let her know he is awake and to share what kind of work he has planned for the day.

His grandmother is happy to receive these messages, and their communication has become a natural part of his routine.

He also said that when he next has a chance to visit his family home, he would like to eat plenty of food, get some rest and make macarons for his grandmother.

Having learned recipes from her when he was younger, Iwase now hopes to treat her to something he has made himself.

His mother and grandmother have also influenced his everyday personal-care habits.

In a 2026 interview with ViVi, he recalled being taught from childhood to brush his teeth carefully.

He said that he now uses dental floss every day and visits the dentist regularly for professional care.

These family memories continue to appear in Iwase's daily life, from cooking to simple routines connected with personal grooming.

In another 2026 interview with GINGER, he talked about carefully selecting the photographs and music he shares on social media.

He enjoys finding music that matches the atmosphere of an image, then combining it with fashion to create a consistent visual style.

Beyond expressing himself through acting, he clearly enjoys thinking about how photos, fashion and music come together in everyday creative projects.
