Does the Japanese copy come with language options? No, it certainly doesn’t! Not even English.
I just bought the game recently in Japan and couldn’t find the English option. Therefore, its not in English. It seems that Koei company Japan has gone Edo on its games for Nintendo. This version is made exclusively for Japanese people. That’s pretty much what the person in the shop conveyed upon asking.
So, if you live in Japan like I do, don’t buy the Japanese copy. Save your money, unless you want to improve your Japanese skills.
For a popular franchise like Zelda there should be a clear marking on the packet to say ‘exclusive to Japan’ at least.
