Yudetamago

Yudetamago (ゆでたまご^?) is the pen name of the Japanese manga artists duo consisting of story writer Takashi Shimada and artist Yoshinori Nakai. They are best known for the popular manga Kinnikuman, Ultimate Muscle (Kinnikuman Nisei), and Tatakae!! Ramenman. Many English speaking fans abbreviate Yudetamago as "Yude" while discussing the different peculiarities of the duo.

Shimada Takashi (嶋田 隆司,^?)

Nakai Yoshinori (中井 義則^?)

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 Yajuu 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 pen name Takayoshi Motoyama (元山 隆義,, Motoyama Takayoshi^?), a fusion of their respective pen names at the time.
