I would add I know that some of the Catholic churches in Tokyo have people who speak English and can provide assistance in English.
And for something entirely off-topic, I think the Roppongi Church in Tokyo has a wonderful live sing-along concert of Haydn's Messiah Hallelujah Chorus, early in the soon-to-begin Christmas season. (I attended it years ago.) Be prepared to sing! (Everybody who can sing the bass part please raise your hand...) When I was there, they did an excellent job, with only a piano as accompanyment.
Thanks guys! Your info does help. I don’t live in Japan. The reason I asked because when I learn a language I would like to use it in the meantime as much as possible regardless of mistakes I could make. I often grab the chance as much as possible to write in the language or even think in the language. I’m a Catholic so sometimes I would need the terminology for writing my schedules and so on.
