If there is one place that you should go to while visiting this country, you MUST go to Tokyo. This city provides you with the quintessential Japanese experience. We took the bullet train up from Osaka, a quick and easy ride that covers a distance similar to that between San Francisco and Los Angeles.
What to Do: We only spent two days in the city but were able to pack a ton in. For instance, I hung out in a cat cafe, which is what it sounds like — a simple cafe filled with hoards of cats that you can pet and play with. If you're not a cat person, there's also an owl cafe!
