In 2019, sponsorship was the biggest revenue stream for eSports in Japan, accounting for more than 75 percent of overall eSports revenue. The domestic eSports market size during that year was estimated at a value of more than six billion Japanese yen.
eSports are video game competitions of mostly professional players competing in games of several genres, ranging from multiplayer online battle arena (MOBA) to card games. These events are often broadcast to a larger audience via live streaming. Several news reports referred to 2018 as the year in which Japan embraced eSports, partly because the Japan Esports Union (JESU) was formed in February of that year.
