Ooedo-Onsen-Monogatari, located in the popular Daiba area, opened in 2003 as TokyoÕs first and only onsen (hot springs) theme park. Inside the building, constructed in traditional Japanese style, there are baths fed by natural hot springs pumped from 1,400 meters underground, open-air baths perfect for enjoying fine weather or starry night skies, a foot bath set in a large Japanese-style garden, and plenty of other bathing facilities. There is also a re-creation of a traditional street from the days when Tokyo was called Edo to offer visitors an authentic onsen experience that is sure to be one of the highlights of their trip to Japan.

You can also make an appointment with the ever-popular Doctor Fish to nibble away at your hands and feet, or get buried in hot sand for fifteen minutes.

The chicken nuggets I just bought have a product code very similar to the number of the credit card that I used to pay for them. When choosing coin lockers and the like I always try to get magic numbers like 42 or 2307, and I derive great pleasure from convenience store purchases that exactly add up to the amount of change in my pocket (or the charge left on my Suica or Edy card). I would really like to buy something to match the credit card, or my phone number, or Pi. There must be a searchable database of product codes online somewhere, but would that be cheating ?
