Language settings
To set Claude Code to Japanese, run /config and set Language to Japanese or 日本語.
You can also use Language to set a tone in addition to the language.
This only changes the language Claude uses; the config UI itself stays in English.
Added
languagesetting to configure Claude's response language (e.g., language: "japanese")
This is supported since 2.1.0.
Setup steps
Configure inside Claude Code
Launch Claude Code, type /config, and press Enter.
When the settings screen appears, move the cursor to Language with ↓ and press Enter.
An input field appears. Enter Japanese or 日本語 and press Enter.
Now the default language for Claude Code is Japanese. Press Esc to exit the settings screen.
~/.claude/settings.json
Alternatively, add the following to ~/.claude/settings.json.
This has the same effect as setting it via /config.
Hide account info shown at startup
When Claude Code starts, it shows your email address and session history.
If you want to hide that, set the environment variable CLAUDE_CODE_HIDE_ACCOUNT_INFO to 1.
If you only want to hide it for a specific repository, add the same setting to .claude/settings.json inside that repo.
Play a notification sound when tasks finish
To detect when a task finishes, add a hook to play a sound.
Add the following to ~/.claude/settings.json (macOS example).
On macOS, pick any file from /System/Library/Sounds/ and update the path after afplay.
If you use both Codex and Claude Code, it might be nice to set different sounds for each.
Choose the directory for Plan mode output Unverified
In Plan mode, generated plans are saved under ~/.claude/plans/ by default.
You can change the destination via plansDirectory in settings.json.
Added
plansDirectorysetting to customize where plan files are stored
If your team uses Claude Code and you want to review how others planned their implementation, you can set this per repo in .claude/settings.json and include the plans in PR reviews. That makes it easier to spot weak planning and also a good way to share knowledge.
