Takizawa, nicknamed "Tackey" (sometimes spelled as its literal romanization, "Takki" (タッキ)), is best known for his drama works, and Tsubasa for his dancing ability.
They started out as backdancers for better known teen idols in their label such as KinKi Kids (who also had not yet debuted at the time) in 1995, when both were 13 years old.
In 1999, Tackey asked Tsubasa to join him in their first duet during the "Johnny's Juniors First Concert" in Tokyo, Japan.
In February 2001, it was announced that the two would be headlining their first tour, called "Takki and Tsubasa 21st-century Showdown with all Johnny's Juniors".
Tackey asked his fans to organize a letter campaign to Johnny & Associates to let them debut as a duo.
To date, Tackey & Tsubasa have released 10 singles, 3 albums and 3 DVDs: a significantly smaller number compared to their counterparts in the company.
The two also share a very close friendship, being best friends; this aspect of their relationship is obvious through their interactions and interviews and is a very important part of the dynamic between them.
