i have a macbook pro mid 2015 15inch with a japanese layout keyboard,

i want to replace it to a US version layout keyboard by replacing the uppercase

will it be possible? same year model but different layout thank you

There’ shouldn’t be any issue at all in replacing topcase, besides the keyboard differences a japanese topcase is just the same as any other if model and year are the same.

Yes it can be done! Its a lot of work. You’ll also need a new battery as Apple glue it in..
