Japanese only

English Dictation

Available today as a Japanese-only interface while the English version is still being prepared.

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.
