Going around Tokyo has been so easy. The subways are full of English signs, and they move fast. Fast! I can get to Ginza in 10 minutes, and to Ueno, which is almost the opposite end of Tokyo, in 22. The only difficulty is the stations themselves, which wind around crazily for transfers sometimes and have multiple exits that are rather far apart. In addition, the system is made up of Tokyo Metro lines (the majority), four private lines run by Toei, and the JR network, which is more like a commuter rail. So if you buy a day pass, you need to know which lines you want, or else you may just be wasting money. Stations are clean and most have bathrooms.
Today, however, I take a break from Tokyo and go out to Kawaguchi-ko, one of the five lakes around Mount Fuji. Wish me luck. I will try to blog from there if I can.
