According to the website Japanese Particles Matter, which was the first thing i clicked in google, "Sanpo is the Japanese word for 'walk'" I love to walk, and when my Japanese friend Yamamoto San visits from Tokyo we always spend one day walking around New York City. We call this our "SANPO CLUB" You cant actually join our Sanpo Club but you can do the next best thing and buy one of these super cool shirts!
