A stamp rally is an event or course dedicated to collecting stamps that follow a certain theme at sites such as train stations, rest areas, tourist attractions, museums, zoos, onsen towns, shopping malls, and other locations. The popularity of stamp rallies in Japan started with the phenomenon of eki stamps. The distinction is that stamp rallies usually follow a certain theme and only appear for a limited time, in contrast to standard eki stamps bearing the likeness of a station, which are usually available forever, or until they are redesigned. The term "stamp rally" is a wasei-eigo invention.
Insider tip — Edogawa Ward in eastern Tokyo borders Chiba Prefecture along the Edogawa River, a flat, low-lying area with a rich shitamachi heritage and a large diverse population. The sento draws sodium-chloride thermal water from deep sedimentary aquifers; the water here is notably dark with high organic mineral content, and bathers emerge with visibly softer skin. The Edogawa riverside cherry blossoms and the nearby Gyosen Park Aquarium make for a full neighbourhood outing.
