Jōji Morikawa (森川 常次), often romanised as George Morikawa (森川ジョージ), is a Japanese manga artist affiliated with Kodansha. He was born January 17th, 1966 in Tokyo and is a graduate of Matsubushi High School (松伏高等学校, Matsubushi Koutou Gakkou) in Saitama Prefecture.

He is the author of Weekly Shonen Magazine's flagship series Hajime no Ippo, which won him the 15th Kodansha Manga Award in 1991. He later won the 43rd award in 2019.

He is also the owner of the boxing gym JB Sports Gym and occasionally acts as a second for some of his gym's boxers.


When Morikawa was 4 years old, he would watch the anime, Harris no Kaze (ハリスの旋風) by Chiba Tetsuya, who he became a big fan of, and aspired to become a mangaka (Manga Artist). He would always get into fights during middle school and high school.  On the other hand, he also served on the student council. When he was 17, Morikawa released his debut manga, Silhouette Night, while still in high school.

He wanted to join Weekly Shonen Magazine because that was the magazine that Chiba Tetsuya was published in. His first published manga series in 1986 was a soccer series, Kazuya NOW, and then a Formula 1 series, Signal Blue, in 1987. Unfortunately, all of his serialized works were cancelled before completion, but the editing staff would always give him another chance. However, he had a wife and child and times were so hard for him. After the third serialization was cancelled, Morikawa told the editor in charge that the next one will most likely be the last.

Not knowing what kind of series to make, he has trouble with the storyboard. The person in charge at the time was very persistent and encouraged Morikawa until late at night, even to the morning to redo things with the storyboard. Being well-known for having an unparalleled likeness for boxing, he was asked if he wanted to draw a boxing manga, but refused, believing he shouldn't do one just on boxing. They then explained "This is the last one, challenge with your favourite genre, in case you come back.". Morikawa had trouble responding, wanting to come back while having the words, "Last..." and "Challenge..." circling around his head.

Hajime no Ippo orignal cast

The first character chart he drew for Hajime no Ippo.

Then all of a sudden, his hands moved and made a sketch of a boxer. He then became determined and accepted the challenge to make a boxing manga. Remembering Ashita no jō, he stated "I'd like to approach boxing differently", "A High School Boxing Club, I'd like to make amateur boxing the theme".

And so, he began making the Hajime no Ippo manga series of his favourite sport, boxing. Started in 1989 and still in serialization as of 2019, Hajime no Ippo became a huge hit and has indeed become the flagship series of Weekly Shōnen Magazine. It has sold more than 96 million volumes.

On April 24, 2019[3], Morikawa announced that he is sponsoring a Class A Tournament for Featherweight boxers with Dangan Promotion to help promote boxing and 30 years of Hajime no Ippo, where 8 boxers will take part to win a prize of 1 million yen.On May 10th, 2019, Morikawa received the 43rd Kodansha Manga Awards.
