Kinnikuman Wiki

Yudetamago (ゆでたまご lit. Boiled Egg) is the pen name of the mangaka duo consisting of story writer Takashi Shimada and artist Yoshinori Nakai from Osaka, Japan. They are best known for the popular manga Kinnikuman, Kinnikuman Nisei, and Tatakae!! Ramenman. Many English speaking fans abbreviate Yudetamago as "Yude" while discussing the different peculiarities of the duo.

Meeting and Debut

In 1971 Nakai was transferred to Osaka Municipal Suminoe Elementary, where Shimada was attending the 4th Grade. They had different classes but lived in the same apartment building and got to know each other while riding the bus to school. One day in the 5th Grade when Nakai went to play at Shimada's house, Shimada showed him his pictures of Kinnikuman.

When they both graduated to Osaka Municipal Nanryo Middle School, they began collaborating on manga ideas. Their first was an action manga called Yajū no Kiba (野獣の牙 Wild Fang), but they then experimented with other genres, such as baseball, karate, and romance. At first they drew strictly on notebook paper, but in the 8th Grade they drew Ramen-ya no Ton-yan (ラーメン屋のトンやん) on art paper and won the Kintetsu Manga Award. At that time they went by the penname Takayoshi Motoyama (元山隆義 Motoyama Takayoshi), a fusion of their respective names at the time.

After they completed Hatsushiba High School and graduated to college, they continued to submit works, hoping to become mangaka. From that point on, Shimada and Nakai began to share the story and art respectively. When they were 16, they submitted their wrestling mangas Gong desu yo (ゴングですよ, Ring the Bell) to the Akatsuka Award and Mammoth (マンモス) to the Tezuka Award. Though neither won, they were noticed by an editor at Shueisha and offered to do a one shot.

In 1978, Kinnikuman almost won the 9th Akatsuka Award and then debuted in the 1979 #2 (December 1978) issue of Weekly Shonen Jump. Although the editorial staff viewed it as a childish work that was popular, then editor-in-chief Shigeo Nishimura saw through this and headed for Osaka in order to persuade their parents into letting them become professional mangaka. At the time, both young men were already looking for jobs, but Nishimura promised to take care of them and even got them an apartment in Tokyo. In May 1979, Kinnikuman began serialisation.


In 1978, Kinnikuman almost won the 9th Akatsuka Award and then later began serilization in Weekly Shonen Jump.

Though originally a gag manga, from halfway through on it was a wrestling manga and became a big hit, later gaining an anime adaptation. There was also movies, special chapters, and infobooks. Also, the Chojin who appeared in the series soon appeared as keshi known as Kinkeshi, which became very popular amongst children and later came to America as M.U.S.C.L.E..

In 1982, the Kinnikuman character Ramenman became so popular that Yude made a one-shot chapter about him was made for Shueisha's Fresh Jump. This led to a monthly series entitled Tatakae!! Ramenman.

In March 1985, Kinnikuman won the 30th Shogakukan Manga Award.

After Kinnikuman ended, they tried several other genres of manga, but none of them ever became a big hit. In 1998 a sequel to Kinnikuman entitled Kinnikuman Nisei began serialisation in Weekly Playboy and became their second big hit. It also started the Revival Manga boom.

However, Nisei was put on hiatus, and the original Kinnikuman manga would be continued twenty-four years after it ended, starting in late 2011. Each new chapter is now published online generally weekly on the Shueisha Playboy (ShuPure) website, while the new manga volumes are published by Shueisha's Shonen Jump.

  • Yudetamago have made short cameoes in the Kinnikuman movies, playing bit parts like minions or audience members.
  • The name Yudetamago was decided on (depending on the member you ask) by either the snack they were eating one day, or the smell of a fart one of the duo released one day. (reference: Ultimate Muscle 17 introduction)
