Around three quarters of Japan is mountain and forest, which pushes almost everyone onto the eastern coastal plains and makes the country far narrower in practice than 377,975 km2 suggests. Forty-seven prefectures, eight traditional regions and more than 14,000 smaller islands, and yet a first visit usually runs along a single rail corridor with Tokyo at one end and Kyoto and Osaka at the other. Tokyo is the capital and largest city of a country of almost 123 million people. Hokkaido in the north and Okinawa in the south are different climates rather than day trips, and both need their own week.

Common questions

How long should a first trip to Japan be?

Ten to fourteen days supports four or five days in Tokyo, three or four in Kyoto, and two or three in Osaka. Add Nara or Himeji only after those bases have enough time, and avoid turning every rail stop into a hotel change.

What entry documents are needed for Japan?

Japan's visa exemption or visa requirement depends on passport and travel purpose. Confirm the current rule through Japan's Ministry of Foreign Affairs or the embassy responsible for the traveller's residence.

What is the best way to travel around Japan?

The Tokaido Shinkansen links Tokyo, Kyoto, and Osaka, while local rail and buses cover city travel. An IC card simplifies many local journeys but does not replace every reserved long-distance ticket, and luggage forwarding can reduce friction between bases.

When is a practical time to visit Japan?

March to May and October to November are broad options for the main-island route, with blossom and autumn periods creating concentrated demand. Confirm regional weather and reservations for the exact cities rather than assuming one national season behaves uniformly.

What money and payment basics apply in Japan?

Japan uses the yen (JPY). Electronic payment is common but not universal, so carry some yen for smaller businesses, ticket machines, or rural transport without assuming that one stored-value card works for every purchase.

What practical safety details should I save for Japan?

Japan's emergency numbers are 110 for police and 119 for fire or ambulance. Type A sockets operate at 100 V, which is lower than in the other wave-A countries, and mains tap water is recorded as safe.
