Anecdotal: in one of the Japanese companies I've worked at, we had to do a Japanese-speaking-only follow-up after every meeting with the global team, as the majority of the team were relying on a machine translator. Every so often this ended up requiring a follow-up to a follow-up where the local team has questions but unable to ask due to a language barrier. It slowed down the progress considerably. Another thing I've found particular interesting is that this language barrier also seems to cause some technique or design pattern to be extremely popular among the local developers out of proportion to the English-speaking world. For instance, Clean Architecture is extremely popular in certain industry (e.g., SI). I believe, it was due to the book having a decent Japanese translation, the lack of Japanese-language commentary against it, and the tendency to follow manuals due to social norms.
