English to Japanese
Paste English in, get Japanese out. It is free, it needs no account, and every result names the model that produced it and the language it detected — so you can tell a confident translation from a guess.
About English to Japanese
Japanese has no spaces between words and several levels of politeness. Short input gives the model very little to judge register from, so a one-word request may come back more formal than you meant.
What you get with the result
The provider and model that answered, the language actually detected in your input, and a way to correct that detection if it got it wrong. A translation with no attribution is one you cannot judge, which is why nothing here returns a bare string.
Questions
Is English to Japanese translation free here?
Yes. Text translation is free with a generous daily cap and no account. A Leumas membership lifts the cap and adds saved history, documents and live conversation.
Can I hear it spoken?
Yes, and that is free permanently. The speak page reads any text aloud in either language, at any tier, with no account.
