If you submit a document in a foreign language as evidence in a civil action, you must attach a translation of the Japanese.
About a year and a half ago, when we submitted six papers on pollution-related diseases in English as evidence at the same time, we added the first Japanese translated by AI as a translation.
Since then, AI translation capabilities have been improving, so we have decided to use AI to translate some of our blog articles into English and publish them on a trial basis.
