Most train stations and tourist offices will have coin lockers or some kind of left-luggage service. Even if there isn’t an official service on hand, most accommodation or tourist office staff will be happy to look after your luggage when asked.
Convenience stores are ubiquitous in Japan. Even some of the smaller towns may have a 24-hour convenience store with snacks, ATMs and toilet facilities.
Japan has a consumption tax, so the price tag you see may not match the actual amount you pay – but you are extremely unlikely to be ripped off in a Japanese shop. There are tax-free shopping opportunities for foreign visitors – check government websites for details.
One thing that many first-time visitors to Japan mention is its cleanliness, despite the vast urban sprawls. However, there is a lack of bins, except outside some convenience stores and on some train station platforms, so people are expected to take their rubbish home with them.
It never hurts to bone up on the do’s and don’ts prior to any visit. The basics in Japan include not wearing shoes indoors, using the hot springs properly, eating according to the local etiquette, and avoiding speaking loudly on trains.
