Frequently asked questions

Are all the Japanese tools free?

Yes — every tool is free, needs no account, and has no usage limit. They run in your browser and return results instantly.

Do I need to install anything to type or convert Japanese?

No. The keyboards, converters, and charts all work online with nothing to install — useful on a device that has no Japanese input set up.
