Digital Games Expo 2021 was held in Akihabara UDX on 14th November 2021. The Digital Games Expo is an event dedicated to indie and “doujin” games.

Digital Game Expo 2021While doujin games used to be exclusive to PC, the ease of development in recent years has resulted in a diversity of platforms, and we saw games for PC, phones, both contemporary and retro game consoles, and VR.

What ARE doujin games, though?
While western indie games came into the limelight in the late 00s, Japanese hobbyists had been creating and distributing games for platforms such as the MSX and X68000 on a large scale since the 80’s, at events such as Comic Market (some even argue that the history of doujin games goes back as far as the 70’s).

Japan thus has a rich history of independent developers and hobbyists working on games, as well as a large following. For the most part of their history, however, doujin games were mostly distributed on physical media at local events, meaning that they had low visibility outside of Japan. This has been gradually changing in recent years, with the advent of digital storefronts that distribute such games, and publishers willing to pick them up.


Some famous franchises even have their roots in doujin games: For example, Type-Moon, famous for the Fate series and especially Fate/Grand Order which is one of the highest-grossing mobile games of all time, was first made famous by their doujin game Tsukihime (which had a retail release for its remake earlier this year).

The boundary between doujin and indie games is ambiguous, but the rule of thumb is that indie games are generally created to be products by professionals or semi-professionals, while doujin games are generally created by hobbyists for fun, but one can find many exceptions to this, and the difference (or lack thereof) between the terms is a frequent hot topic for discussion.

Today, doujin games account for 5% of all doujin (fan/hobbyist) works altogether. While this might not initially sound like much, one should consider the sheer scale of doujin activity in Japan, with Comic Market 97 having 32,000 participating doujin circles, and a total of 750,000 participants in the event overall.

Digital Games Expo 2021 was the ninth time this annual event was held since 2013, and had over 100 participating entities – Companies, “doujin circle” hobbyist groups, individuals, and even a “multimedia content creation club” of students from a university from a different prefecture.

Due to the sheer number of participants, it would be hard to cover all of them, and so we are only able to show off a fraction here: Anyone who is interested in seeing more should check out the complete list of participants available on the official website.

Jeddom - デジゲー博2021Jeddom (@Jeddom on Twitter) is an independent developer who had an interesting idea to show off at the event: A running game where the character runs forwards automatically, and the player times and controls jumps using an arm bar (a gym tool typically used for training chest muscles).
