Tsumiru

Coming from Mihon or Komikku ​

Suwayomi restores Mihon's backup format directly, so moving from Mihon or Komikku is one backup file: create it there, restore it here.

What actually changes ​

One conceptual shift: in Mihon, sources and extensions run on your phone. With Tsumiru, they run on your Suwayomi server, and Tsumiru is a client you point at it, on as many devices as you like.

The tradeoff: you run a server. In exchange, every device shows the same library, categories, and reading progress, and your phone is no longer the only copy of your library. If running a server isn't for you, Mihon remains the better fit; see how they compare.

1. Set up a Suwayomi server ​

Skip this if you already have one. Suwayomi-Server is free and open-source and runs on Windows, macOS, Linux, Docker, or a NAS/home server.

Then install Tsumiru from the download page and connect it to the server. Getting started covers the setup wizard.

2. Create a backup in Mihon ​

In Mihon, go to More → Data and storage → Create backup, leave everything selected, and save the file. You'll get a .tachibk file. Komikku's backup lives in the same place and uses the same format.

(Menu names drift between releases; if yours looks different, look for a backup option under data or storage settings.)

3. Restore the backup ​

The restore happens on the server, and Tsumiru can drive it:

  1. In Tsumiru, go to Settings → Backup & Restore → Restore Backup.
  2. Pick your .tachibk file.
  3. Tsumiru validates it first and lists any missing sources. If some are missing, install those extensions (next step) and run the restore again so everything resolves.

You can also restore through the server's own WebUI if you prefer; the result is the same.

WARNING

Restoring merges into whatever library the server already has. On a fresh server that's a non-issue; on an existing one, create a server backup first.

4. Install matching extensions ​

Extensions now live on the server, but you manage them from Tsumiru:

  1. Add the extension repos you used in Mihon under Settings → Browse → Extension Repository.
  2. Open Browse → Extensions and install the sources your library uses. There's a language filter, and installing from a file is supported for anything not in a repo.

Once installed on the server, the sources are available to every device you connect.

What carries over, and what doesn't ​

Carries over: your library entries, categories, and read history. That's the core of a Suwayomi backup, so a restored .tachibk puts your series back in their categories with chapters marked read.

Doesn't carry over:

  • Downloaded chapter files. Mihon's own backups never include them, so there's nothing to transfer. You'll re-download on the server side; see the next section.
  • Local series (Mihon's local source) travel as entries, not files. Copy the files to your server's local source directory if you use it.
  • Mihon's app settings. Tsumiru is a different app; reader and appearance preferences are set up fresh.
  • Custom covers aren't in Mihon backups.

Tracker bindings are part of the Mihon backup format, but check the Suwayomi restore notes for what a restore preserves on the server side. Either way you'll sign in to each tracker again; see below.

After the move ​

Two things replace habits you had in Mihon:

  • Device downloads → Offline reading. Set a keep rule per series (next 5/10/25 unread, all unread, or everything) and Tsumiru keeps chapters on your device automatically. The server fetches from sources; your device syncs from the server.
  • Trackers → Tracking. Sign in to AniList, MyAnimeList, and the rest under Settings → Tracking, then check each series' bindings.
