Masato Wada

In October 2004, Wada joined the Watanabe Entertainment group named the D-BOYS. He is currently, the oldest member in the group. As a member of the D-BOYS, Wada also keeps a blog, which he updates regularly. Being a part of the D-BOYS provides Wada with a lot of opportunities. Among them is to perform with the group of boys and expand his experience as a performer. The D-BOYS so far have released two photobooks. The first photobook released on April 27, 2005, was self-titled D-Boys, while the second, released on March 15, 2006, was called Start, both which contain many photos of Wada.

The D-BOYS starred in their own drama documentary variety series called, DD-Boys[2] in which Wada's appeared in many episodes as himself. The show was 24 episodes long and ran from April 10 to September 25, 2006. In June 2007, the D-BOYS starred in their very own musical together called, D-BOYS STAGE,[3] which ran from June 3 to 10 at the Space Zero theater in Tokyo. Wada only appeared in the musical as a guest performer, making select appearances on June 4 and 7.

In 2005, Wada won the role of Sengoku Kiyosumi, the "lucky" 3rd year regular of Yamabuki Middle School's tennis club in the Prince of Tennis musical series, Tenimyu. From 2005 to 2007, he was the first and only actor to play Sengoku. He made his debut on January 8, 2005 in the Side Yamabuki performance in Osaka. The musical marked his first major debut on stage. During his run in the musicals, he was able to work with fellow D-BOYS members Yuya Endo, Kotaro Yanagi, Masaki Kaji, Hiroki Suzuki, Hirofumi Araki, Osamu Adachi, Tomo Yanagishita, Kōji Seto, and former member Yuu Shirota. His last musical appearance as Sengoku was in the fourth Dream Live concert in 2007.

Wada was not able to carry on his role from the musicals to the live-adaptation film of the manga series, because the character of Sengoku, as well as the entire Yamabuki team, does not appear in the film; however, he was able to make a small cameo in the film as Kintarou Tooyama, a member of Seigaku's rival team, Shintenhouji. The cameo appearance marked Wada's first film debut.

The Prince of Tennis was released on May 13, 2006 and opened in the tenth spot in the Japanese Box Office.

Then, Wada appeared in the TV drama, Fushin no toki -Woman Wars (だめんず・うぉ~か~)[4] as a minor character, named Nogami Toshiya, which premiered on Fuji TV July 6, 2006 and broadcast until September 21, 2006.

Afterwards, Wada appeared in the TV drama, Damens Walkers (だめんず・うぉ~か~)[5] as a businessman, named Fukuyama Ichitarou, which premiered on TV Asahi October 12, 2006 and broadcast until December 7, 2006. The drama was based on a popular comic book by Mayumi Kurata, about beautiful women that end up having relationships with worthless men that cheat and lie.

Wada appeared as a businessman, named Baba Atsushi, in the TV drama, Konshuu, Tsuma ga Uwaki Shimasu (今週､妻が浮気します),[6] which premiered on Fuji TV, January 16, 2007.

In 2006, Wada had appeared in the TV drama special, The Hit Parade,[1] starring as Keijiro Yamashita.

Then, in 2007, it was announced that Wada would also be starring in the Watanabe special musical, The Hit Parade,[7] the musical version of the TV drama special, Hit Parade that Wada had starred in. Performances will run from July 10–31, 2007 at the Aoyama Theater in Tokyo and will also run from March 31, 2007 to April 1, 2007 at the Le Theatre Ginza in Tokyo.

Shigeshoshi (a.k.a. The Embalmer) became Wada's first opportunity to take the lead role in a television serial. Based on the manga of the same name by Mihara Mitsukazu, the series centered around embalmer Mamiya Shinjuro, and the understanding of the nature of life and death that he gains through his work. Shigeshoshi aired on TV Tokyo from October to December 2007, and also featured fellow D-Boys, Igarashi Shunji and Kaji Masaki.
