Takechi Kaisei (武知海青) is a Japanese performer and a member of the group THE RAMPAGE.
He auditioned to the EXILE PERFORMER BATTLE AUDITION (to find a new performer for EXILE) and made to the finals, but was not selected. He was announced as a candidate for THE RAMPAGE in April 2014 and became an official member in September of the same year.
Takechi Kaisei was born on February 4, 1998, in Takarazuka (Hyogo Prefecture), Japan. He has two older sisters.
He began swimming at the age of 2 and became so successful that he competed in the Junior Olympics in swimming when he was in 5th grade. After entering high school, he continued his swimming career and was particularly known for his Butterfly stroke which was even shown on the TV program Mecha² Ike Teru ~tsu! (めちゃ²イケてるッ！) as part of a collaboration with a swimming competition.
Since his mother runs the dance school "T’s-BOX" in their hometown, he also started dancing when he was about 3 years old and by the time he was in middle school, he had won various dance contests. In his early teens, he was part of a performance team called "Radiation" which focused on contemporary dance and took part in local competitions and events such as DANCE ATTACK. Moreover, he was a member of the dance teams "AVANTI" and "Rhsmmm" too.
Takechi had been dreaming of becoming an EXILE performer since he saw the group on TV when he was in the lower grades of elementary school. Thus, he started attending EXPG Osaka and became a scholarship student later on. At the age of 16, he participated in the EXILE PERFORMER BATTLE AUDITION and was able to remain as a finalist. By the time of this audition, he had already been dancing for 13 years. Even though he wasn't able to be finish as a winner, he was selected to become a candidate for the upcoming EXILE TRIBE group THE RAMPAGE.
After completing the group's musha shugyo, Takechi went from being a candidate to an official member and made his major debut with THE RAMPAGE on January 25, 2017, with the single "Lightning".
On November 16, 2019, he took part in the Summer Style Award 2019 ROOKIE CHALLENGE CUP, a beauty and body competition to determine the best-looking man for summer in Japan, and won the first place. At the end of the year, he also participated as a contestant in the athletics-focused variety program SASUKE that aired on TBS.
On February 17, 2020, it was announced that Takechi would be one of 10 LDH members participating as torch runners in the Tokyo Olympic Torch Relay on July 23. Although, the relay was cancelled as the Olympics in Tokyo was postponed to 2021.
