Mitsuteru Yokoyama (横山 光輝 Yokoyama Mitsuteru , June 18, 1934 - April 15, 2004) was a Japanese manga artist born in Suma-ku, Kobe-shi, Hyogo. His personal name was originally spelled Mitsuteru (光照), with the same pronunciation. His works include Tetsujin 28-go, Giant Robo, Akakage, Babel II, Sally the Witch, Princess Comet, and adaptations of the Chinese classics Outlaws of the Marsh and Romance of the Three Kingdoms.
Early life 
Yokoyama spent his boyhood during World War II and was evacuated to Tottori with his family. He graduated from Kobe municipal Ota junior high school and went on to the Kobe municipal Suma high school. Osamu Tezuka's "Metropolis" made a deep impression on Yokoyama who wished to become a manga artist in earnest and so he contributed his works to a comic book in his high school days. He entered the Sumitomo Mitsui Banking Corporation after graduation from high school, but quit his job before five months passed because there was no time to draw a manga. He found a new job as a publicity department member for a movie company based in Kobe and pursued his manga artist career on his free time.
Professional career 
Yokoyama came out with the book "Otonashi no Ken (音無しの剣 Sword without sound )" for his manga artist début, which caught Osamu Tezuka's attention.
In 1955, Yokoyama had a title serialized in the magazine Shōjo for the first time, "Shirayuri Koushinkyoku (白ゆり行進曲 White Lily March )".
In 1956, "Tetsujin 28-go" appeared serially in the magazine Shōnen after he resigned from the movie company. "Tetsujin 28-go" became a popular work equal to Tezuka's "AstroBoy and its animated adaptation also made a smashing success. This prompted Yokoyama to become a full-time manga artist and to move to Tokyo the same year.
In 1964, he established Hikari Production, an incorporated company. Making good use of his vast exposure to movies during his previous job, he produced consecutive popular hits in various genres, both in comics and anime, such as "Iga no Kagemaru (伊賀の影丸 Kagemaru of Iga)", "Akakage", "Sally the Witch", "Giant Robo", "Babel II" and so on. With the writing of "Suikoden (水滸伝 Water Margin)" (1967–1971) and "Yokoyama Mitsuteru Sangokushi (Records of Three Kingdoms)" (1971–1986), he began a new chapter in his career as he drew mostly comics based on original stories with material from China's and Japan's History.
In July 1997, Yokoyama was hospitalized with myocardial infarction and had an operation. He returned to work in next year March.
In 2004, while under medical treatment, Yokoyama won the MEXT Prize of the Japan Cartoonist Association.
On the morning of April 15, 2004, Yokoyama suffered burns all over his body due to a fire breaking out in his house. His condition deteriorated and he fell in a coma. Yokoyama died in the hospital near his home at 10:00 PM on the same day, aged 69.
The attractions of Yokoyama's works are calculated story deployment and an elaborate setting. On the other hand, Yokoyama liked light characterizations and didn't let characters show their feelings too much. He was better at a serious story manga rather than with comedy, but he drew some also.
Yokoyama is one of the originators of present day Japanese comics. While Tezuka established the technique to draw Japanese comics, it was Yokoyama who established the format of various genres of current Japanese comics and anime. Whereas many comic artists prefer their original stories not to be changed when adapted, Yokoyama was realistic and tolerant, so many of his works were made into animation or Tokusatsu.
