Japanese-only tools for now
These tools are still public, but their current interface is Japanese-only. They are listed here explicitly instead of in the English primary navigation.
What this portal is for
Short practical tools for checking, practicing, calculating, and reviewing in a browser tab.
How it works
Most tools keep settings and history in your browser so they stay fast to open and easy to revisit.
Trust and navigation
The English navigation links only to translated routes. Shared legal and contact pages stay available on every tool.
About the translated routes
The translated routes are being expanded gradually. The English portal stays scoped to routes that are already translated so navigation remains predictable.
Contact details and site policies are available via the about page, privacy policy, and terms.
