Help with Translations

Hi everyone,

I'm just starting to learn some phrases while I convince my partner to go on a holiday to Japan with me. I've seen some phrases that say "do you speak English?" but a friend told me not many Japanese people learnt to speak English in school but they spend a long time learning to write it so I wanted to add "can you write English?" to my vocab but I wanted to your opinion on the google translate and possibly get some suggestions. Thanks
