American, Canadian, and New Zealander tourists can stay in Japan for up to 90 days without requiring a visa (a valid passport is, of course, required). Americans cannot work for money while in Japan, and tourists must leave after 90 days. Australians must possess a passport and three-month entry visa. United Kingdom citizens may stay for 180 days without a visa.
Visitors who require visas to stay stay longer must contact the nearest immigration bureau; it’s a good idea to contact your local consulate or embassy before leaving for Japan to clarify visa requirements as regulations are subject to change.
All tourists are required to carry their passport at all times. Those driving in Japan need to possess an international driver’s license.
