Two years ago, on an eight-day trip to Tokyo (which produced my D+R profile photo) I took a 55-minute cruise on the Himiko boat down the Sumida river from Asakusa to Odaiba. Designed by manga and animé artist, Leiji Matsumoto, it glided into port like a silent spaceship. I have never been so excited to board a boat in my life.
Inside was even better. And that's a good thing, because frankly- there's not much to look at and admire along the Sumida river.
