Digital Games Expo 2022 was held in Akihabara UDX on 13th November 2022. Digital Games Expo, which is also known by its Japanese name “Dejige Haku” is an event dedicated to indie and “doujin” games.

Official website:

Digital Games Expo 2022 was the tenth time this annual event was held since 2013, and had over 200 participating entities – Companies, “doujin circle” hobbyist groups, and individuals.

What ARE doujin games, though?
Japanese hobbyists have 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 last 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.

While doujin games used to be exclusive to PC, the ease of development in recent years has resulted in more diversity in platforms, and we saw games for PC, iOS and Android, retro game consoles, and VR.

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.


Desunoya - Lys and Ruka's Magical Bag
Desunoya – Lys and Ruka’s Magical Bag

Desunoya had a playable demo of the roguelike action RPG Lys and Ruka’s Magical Bag (available on Steam in English). The game’s primary gimmick comes from being able to power up equipment by lining up duplicates, and using a special item to combine different types. For example, combining two different kinds of magic will result in a spell that fires off both types of magic at the same time, and combining a sword and dagger will let the player swing both weapons at the same time.

This time, they teamed up with Aims Co., Ltd. to implement an entire cockpit allowing the player to fly around Mount Fuji.


Electriar Labo had the game Electriar Code, which is available on iOS and Android, on display. Electriar Code has a similar world to that of series like Busou Shinki and Megami Device, in which sentient action figure-sized robots exist and are pitted against each other in battles by their owners. The game is similar to the old Busou Shinki game Battle Rondo (which closed down in 2012), with the player customizing their robot but not actually controlling it in battle: In Electriar Code, fighting is completely automated based on the loadout and AI settings, which keeps in line with the setting. There is a massive range of customization options in the game, and Electriar Labo had a massive number of printouts of user submissions of their robots to look at as well.
