Roco Kingdom Heads to Japan with Closed Beta Set for October 27
The relaunched open-world monster-collector leans on an established Chinese browser-game audience and an explicit no-gacha encounter policy as it opens its Japan closed beta, so the October test is where that design claim gets checked against a new market.

Morefun Studios held a Japan version announcement and hands-on trial for Roco Kingdom at Bellesalle Shibuya First on September 21, ahead of a closed beta starting October 27. Narrative Director Ono said the game has over 350 million cumulative registered users, with more than 15 million on its March 26, 2026 launch day in mainland China. Voice actors KENN and Aina Aiba appeared, and six more cast members were announced.
The game began as a browser title in China and has since been rebuilt as an open-world monster-collecting RPG. Morefun Studios opened the first and last stages of the Japan version at a September 21 event at Bellesalle Shibuya First in Tokyo, with a hands-on trial session and a live voice recording segment.
Ono, the game's Narrative Director and Localization Lead, framed the design around three ideas: encounters, closeness, and walking together. The Jini creatures appear based on weather, interact with one another, and each carries its own habits. The studio states it will not rely on gacha for Jini encounters and will not let monetization decide wins or losses in PvP.
