The official Gunpla fan community "BUILDERS NOTE" is set to launch its service in Japan, an app aiming to support the entire cycle of enjoyment for Gundam plastic models (hereinafter, Gunpla): "acquiring → building → connecting" within a single platform. The app is available for download on the App Store and Google Play starting today, May 12, 2026 (Tuesday).
■ About BUILDERS NOTE
We wanted to create an official Gunpla platform that supports the entire enjoyment cycle of "acquiring → building → connecting" for all Gunpla enthusiasts. With that vision, BUILDERS NOTE has officially launched as an app today. Please refer to previously released press releases for more details.
■ Three Main Features
BUILDERS NOTE supports the entire Gunpla enjoyment experience of "acquiring → building → connecting" all within one app.
① "Gunpla Reissue Conference" — Bringing your desired kit voices to the reissue consideration table
▶︎ What is the Gunpla Reissue Conference?
The Gunpla Reissue Conference is held four times a year (Spring, Summer, Autumn, Winter). Leading up to each conference, a monthly "Selection Election" voting event is held to narrow down candidate kits for reissue. The voting results are collected and organized through BUILDERS NOTE and shared as a basis for reissue consideration. Kits decided for reissue will be available for general distribution, in addition to a lottery sale within BUILDERS NOTE. Please refer to previously released press releases for detailed mechanics.

*Due to the app release timing, the 2026 Gunpla Reissue Conference is planned to be held three times a year (Summer, Autumn, Winter).
▶︎ 1st Selection Election | Gunpla Reissue Conference 2026 Summer "RE/100" is now underway!
The 1st Selection Election for the Gunpla Reissue Conference 2026 Summer has started today. Please cast your vote for the kit you want to build. Voting and participation are available within the app.
② "Gunpla Production Log" — Accumulated records empower your next creation
▶︎ What you can do with this feature
We want you to enjoy Gunpla at your own pace, even amidst a busy daily life.
The Production Log is a feature that allows you to record each step of your production process—assembly, detailing, painting, decal application, etc.—with photos and comments. Not only can you look back at your journey to completion, but you can also pinpoint and search other builders' processes for technical reference.
▶︎ BUILDERS NOTE "Production Log Contest" also starts today and is accepting entries!
The "Production Log Contest," where you can enter works completed using the Production Log feature, is being held from today until June 30 (Tuesday). Winning entries and their production records will be inducted into the hall of fame as "Best Build" works and will be archived on a special page at a later date!
③ "Official Gunpla Fan Community" — Share the joy of building with others
▶︎ What you can do with this feature
BUILDERS NOTE has previously provided a web version where builders could share their production logs and completed works to interact with each other. For the app version, we focused on enhancing its linkage with the Production Log. By allowing users to directly share in-progress records from the Production Log to the community, or search and reference other builders' posts by process or technique, the app offers a more user-friendly experience that seamlessly connects "building" with "showing and discovering."
Of course, you can continue to use features like posting completed works, exchanging impressions, and AI Diorama that you have enjoyed so far. Please enjoy interacting with other builders, sparked by common interests like "liking the same series" or "challenging the same painting style," or through learning exchanges such as "this technique was helpful" or "I feel inspired."
▶︎ Pro-builder production logs and special columns to be released sequentially!
With the cooperation of Hobby Japan Co., Ltd., production logs and columns filled with production tips from active pro-builders will be released sequentially. You can realistically read about the processes, trial-and-error, and dedication behind completed works through their production records. This content is enjoyable not only for those who want to incorporate the perspectives of top-tier modelers into their own builds but also for those who want to delve deeper into the world of Gunpla production.
■ Release Commemoration Campaign Underway
Multiple campaigns are being held to commemorate the official app release. Please check the official BUILDERS NOTE app and official X (@BUILDERS_NOTE) for details on each campaign.
