The tallest member. He is a fashion lover and is heavily inspired by the alternative scene. He is in charge of SUPER★DRAGON’s outfits and styling, though he also participates in making music as a composer and lyricist.
At some point, he met the fashion designer Syunki in his private life and worked together with them as a stylist ever since SUPER★DRAGON’s “Hey, Girl” in 2022.

Tsuyoshi can get quite serious when it comes to SUPER★
DRAGON and work and he takes a very leader-like role in the group. He is often described as their “dad” or “older brother” and has a reputation for giving long-winded “dad” speeches that go on for too long during their concerts.

Despite his serious work attitude, he can be quite unserious and is "surprisingly clumsy" in his day to day life. He is often described as an “airhead” or a "klutz" and hits his head on the kitchen cupboard maybe twice a day. He is a big Naruto fan, and always liked superheroes such as Kamen Rider growing up. It was in fact Tsuyoshi who came up with the idea for the concept and theme of SUPER X/Dark Heroes. When he was in middle school, he wrote that he wants to become a ninja when he grows up.

Tsuyoshi is a vocalist and a song writer. He is a music nerd and likes to DJ as a hobby, always carrying his USB containing his DJ set with him wherever he goes.
He's a fan of many overseas artists such as Tyler the Creator, Rosalia, Balming Tiger, etc. Songs Tsuyoshi has written for SUPER★DRAGON include Good Times & Tan Lines, Omaejanai, Younger Forevermore, Popstar, Funny Story, and NEBOU.

In 2017, Tsuyoshi, along with fellow member Jean, independently started a joint instagram account called tsuyojean_official out of their shared love for fashion.
They gained popularity as a modeling duo and would appear in magazines and runways together, often credited as “tsuyojean” together as one unit.

The both of them have since made individual instagram accounts and are now more focused on making music, thus updates on this account are now quite rare. They will still (very) occasionally post on it however, as the two have gone on record to say that the account is like "their home". Tsuyoshi and Jean’s fashion tastes tend to overlap, and they are often seen wearing matching clothing items and accessories.

Aside from fashion, they are very "linked musically" and often compose songs together, which is something they've been doing since they were teenagers. They consider each other "partners" (in crime).

He considers fellow member Reo his best friend. They were paired up to write their part of the lyrics for SUPER DRAGON's anniversary song "Funny Story" together, and the line "brings back memories, going home on the Keio line together" is a reference to their friendship, as they used to live near each other when they were kids.

My favorite member along with Jean. He is the reason I discovered Supadora in the first place so he has a very special place in my heart for this reason. One day, I was watching a rather mediocre TV drama with my sibling, when Tsuyoshi came on and was like the best actor in the whole show—basically the show's saving grace. We were so impressed by his acting skills (it also helped that he's incredibly handsome) so we immediately looked him up and ended up discovering Supadora. His most attractive quality to me is his love for fashion and music and art in general. He is someone who really knows what he's talking about when it comes to fashion and culture, and he is also probably the member who is most in touch with the queer community, which is another reason why I love him so much. Imo, he’s actually the most girlypop member.
