When in Japan, the Frugal Flugel recommends 100 YEN SHOPS, where packaged meals and snacks, groceries, water, toiletries, household items and more are available for about a buck. In addition to familiar picnic items like sandwiches, dried fruits and nuts, 100 Yen Shops offer a chance to sample such Japanese treats as sembei (rice crackers), iwashi (sardines) and ika (dried squid).
