I have been saving up for a 2-3 month vacation in Japan. Asked my friend who is stationed in the U.S. Okinawa base for some suggestion/adcvice and he said when he went to Tokyo and spoke a mix of English and Japanese, some people would just shy away from answering at all and just walk away. Was wondering if I should brush up on some Japanese before my trip there? And if I should just hire a translator/travel companion?

Thanks for the advice, I definitely should learn the basics. But I think I might need a translator for when I visit the countryside/sea side.

I am so sorry to ask this dumb question but I am Korean-American... any need to be worried in my stay in Japan?
