Editors' review
The benchmark for machine translation — the business default for Japanese
DeepL established the current quality bar for machine translation. The consensus that its Japanese reads more naturally than Google Translate has held, and that is why it became the default for business document translation in Japan.
Pro starts at ¥1,200/mo with Business and Enterprise tiers above it. There is a Japanese entity (DeepL SE), SOC 2, ISO 27001 and GDPR compliance, and invoice payment in yen — the things that usually decide whether a tool clears procurement here.
It is not a generative writing tool. It translates and rephrases; it does not draft. DeepL Write, for English proofreading, is a different product with a different job.
Verdict
The standard answer for Japanese companies handling English or multilingual documents, and an easy one to get approved internally.
