Frequently asked
Does Japanese Castle - Structure ✅ work on Minecraft 1.21.11?
Yes. 1.21.11 is the newest Minecraft version Japanese Castle - Structure ✅ declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.
Which Minecraft versions does Japanese Castle - Structure ✅ support?
Everything the author has declared, from 1.21 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.
Do I need to install Japanese Castle - Structure ✅ on the client or the server?
The server only. Players join with an ordinary Minecraft client and install nothing.
What licence is Japanese Castle - Structure ✅ under?
LicenseRef-All-Rights-Reserved, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.
How do I install Japanese Castle - Structure ✅?
Data packs install per world: put the downloaded file in that world's datapacks folder and run /reload, or add it when creating the world. No loader is involved. On a server, the world folder lives next to the server jar.
Where do I download Japanese Castle - Structure ✅ safely?
From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
