It’s still more than two months to go, but with a trip of this magnitude, I want to do my homework in time. What draws me most about Japan are two things: Ramen-style noodles and the total and utter madness that Tokyo is said to be. I have seen Bangkok, I have seen Hanoi. I’ve made it through rush-hour Saigon. But I expect Tokyo to top it all. What I’m figuring out at the moment is where to stay.
