My hometown is Tokyo, and also I'm from Tokyo. Tokyo is Japan's capital, and the most populous metropolis in Japan. If you visit Tokyo, you don't have any trouble. You can book the hotel, the restaurant, and the train ticket without a guide.
I like my hometown-Tokyo. Some Japanese people from other prefectures says that the people from Tokyo is not kind and have no compassion, but I don't think these opinions. When I lost my wallet on the road in Japan, a man through the road picked up and returned it to me. If a elder woman stand on the train, some people give up their seats.
