Bluesky Official Events in Tokyo! Meetup and Hackathon

In April 2026, it was announced that official events related to 'Bluesky,' the decentralized SNS rapidly gaining popularity, will be held sequentially in Osaki, Tokyo.

The scheduled events are the 'Bluesky Meetup in Tokyo Vol. 4' user/developer exchange on Monday, April 13, and the practical 'Bluesky Hackathon' on Saturday, April 18. These are viewed as rare opportunities to touch the forefront of decentralized social media, attracting keen interest from the IT industry and beyond.

First, the 'Bluesky Meetup in Tokyo Vol. 4' will be held starting at 7 PM on Monday, April 13. The venue will be the office of Findy Inc. (Osaki, Shinagawa-ku, Tokyo), which provides career support for engineers.

This meetup is an open exchange event where diverse people gather, from general users who use Bluesky daily to engineers developing their own client apps and related services. Past events have seen lively discussions about the future of SNS and the possibilities of decentralized networks (AT Protocol).

This time, lightning talks (LT) by volunteers and presentations on the latest technical trends are planned, making it an excellent place to deepen networking among participants. It's an unmissable event for those interested in the technology behind Bluesky, as well as those who simply want to enjoy the new SNS culture.

Following that, on Saturday, April 18, a full-day 'Bluesky Hackathon' will be held in Tokyo (around Osaki). This will be more practical, with participants forming teams to challenge themselves to develop new tools and applications related to Bluesky.

The greatest feature of Bluesky lies in its open design. By using the underlying technology called AT Protocol, anyone can build their own algorithms or clients. The hackathon is expected to yield innovative features not found in existing SNS and unique services that improve the user experience by making the most of this characteristic.

The appeal of this event is that it welcomes participants from various professions beyond just programmers, such as UI/UX designers and project directors. It's designed as a place where chemical reactions occur when participants from different backgrounds share ideas.

Furthermore, rewards are prepared to boost participant motivation. In addition to commemorative stickers for all attendees, Bluesky original goods (T-shirts, caps, tote bags, etc.) will be presented to teams and individuals who achieve excellent results. These goods are likely to be rare, non-sale items, making them irresistible for dedicated fans.

Behind these events is the remarkable growth of Bluesky in the Japanese market. Since the invitation system was abolished in 2024, the number of domestic users has exploded. Many Japanese find Bluesky attractive as a destination from X (formerly Twitter) or as a completely new community space.

To support this movement, the long-awaited 'Bluesky Japanese Official Account (@jp.bsky.app)' was opened in April 2026. This has strengthened the dissemination of update information and the support system for Japanese users, creating an environment where they can use it with more peace of mind. The opening of the official account is a clear message showing how much the management team values the Japanese market.

With the nature of SNS being reconsidered worldwide, decentralized platforms not dependent on specific companies are thought to play an important role in the future internet society. This series of events in Tokyo should be an important milestone that further increases the passion of the Japanese user community and accelerates the expansion of the new ecosystem.

Event registration, detailed timetables, and speaker information are updated and announced on the '428lab' group page within the IT study group/event management service 'connpass.' Registration may close once the capacity is reached, so if you are interested in the cutting edge of SNS culture or the future of Web3.0-like networks, why not check it out early?
