About
Akira Sakuma (born 1952) is a Japanese game designer and writer, best known as the creator of the Momotaro Dentetsu series — a railway board game franchise set on the real map of Japan that has sold approximately 19 million copies across 25 titles. He spent thirteen years as the lead writer for the Jump Broadcasting Station (JBS), a reader-participation column in Weekly Shonen Jump, before entering game design in the late 1980s. His defining principle: a game must be so intuitive that no manual is needed, and so structured that even the player having the worst time is making everyone else laugh. He received the Agency for Cultural Affairs Media Arts Festival Distinguished Achievement Award in 2021 and the CEDEC Special Award in 2024.
History
Akira Sakuma was born on July 29, 1952, in Suginami Ward, Tokyo. His pen name, written entirely in hiragana, was chosen in homage to composer Koichi Sugiyama, who had similarly adopted a non-standard romanization of his name. Sakuma studied economics at Rikkyo University and joined the first cohort of Kazuo Koike's Gekiga Studio, an influential workshop for manga creators. He would spend much of his early career orbiting manga — writing, editing-adjacent roles, and an abortive attempt to run his own publishing business — before a debt-driven turn into game design changed everything.
From 1982 to 1995, Sakuma served as the lead writer for the Jump Broadcasting Station (JBS), the reader-participation column inside Weekly Shonen Jump. He was not a staff editor at Shueisha; his role was that of a freelance writer. But the column reached up to six million readers per issue, and the thirteen years he spent refining short-form content for that audience became the invisible foundation of his game design philosophy. He learned, through sheer volume of reader feedback, what average Japanese audiences found funny, surprising, or unfair. He filed away every reaction. He would use all of it.
In 1985, Sakuma co-founded Hanadensa, a small publishing company, with Yuji Horii, Takayuki Doi, and others, launching a manga magazine called Manga House. The publication failed to secure proper distribution — copies sold through mail order and a handful of bookstores — and folded after seven issues. The deficit reached two hundred million yen. Sakuma has described the venture as the greatest failure of his life. He now needed income, and Horii — already established in game design as the creator of Dragon Quest — offered a path forward. 'Games pay well,' Horii told him. 'You could cover those debts.' Sakuma took the offer.
He entered game design as a practical necessity and transformed it through obsessive craft. For Momotaro Densetsu (1987), a Famicom RPG built around the Japanese folk hero, he delivered a commercial hit selling over one million copies. But it was in designing the first Momotaro Dentetsu (1988) that he found his true form. He drew the map of Japan on paper with a marker, placed tokens on the stations, and rolled physical dice for months — testing rule after rule before a single line of code was written. Entire mechanics were discarded for adding one extra button press without adding joy. His standard was simple and absolute: if it adds a button and does not add delight, cut it.
The design insight that defines the entire Momotaro Dentetsu series came from an argument about fairness. His collaborator Masuda Shoji pointed out that the Binbo-gami — the poverty god who attaches to the leading player and drains their wealth — felt cruel to the person targeted. Sakuma disagreed. 'If one of three players is miserable and the other two are laughing,' he replied, 'that is a net positive.' He was designing not for individual victory but for the total experience of everyone at the table. The poverty god stayed. It became the most beloved element in the series, and the argument that produced it became the defining philosophy of Sakuma's career.
The PC Engine entry Super Momotaro Dentetsu (1989) locked in the modern form of the franchise: shared destination goals, the card system, and the poverty god fully integrated into the loop. Sakuma carried this formula across 25 titles and four decades, moving through every major platform from Famicom to Nintendo Switch. The series sold approximately 19 million copies in Japan. The 2020 entry, released during the COVID-19 pandemic, sold over four million copies — proof that a game designed for families crowded around a single screen retained its hold even in the years when families were forbidden from gathering.
Sakuma suffered a cerebral hemorrhage in 2012 and a heart attack in 2019, each requiring emergency care. By 2025 he was living in an assisted care facility and using a wheelchair. He continued attending biweekly project meetings with Konami by video call. In 2021, the Agency for Cultural Affairs Media Arts Festival gave him its Distinguished Achievement Award. In 2024, CEDEC awarded him a Special Award for lifetime contributions to the industry. The man who entered game design to repay a two-hundred-million-yen publishing debt left it as one of the most decorated designers in Japanese game history. He repeated the same lesson in every interview, unchanged from the paper-map years: if you are not having fun making it, the player will know. It was the only test he trusted.
