Japan's 47 prefectures

Hokkaido rewards travellers who think in regions rather than trying to circle the island in one sweep.

Aomori sits at Honshu's northern tip, where the Tsugaru plain, Hakkoda mountains and Pacific-facing coast create several distinct travel zones.

Iwate is geographically extensive, and its visitor experiences are divided naturally between the Kitakami basin, Morioka and the long Sanriku coast.

Miyagi is organised around Sendai, a major urban gateway with direct rail connections and enough culture to justify more than a transit stop.

Akita's appeal lies in the contrast between its inland mountain basin, Sea of Japan coast and living traditions.

Yamagata is a collection of valleys and mountain corridors rather than one compact sightseeing zone.

Fukushima spans three major cultural and geographic areas: Aizu in the west, the central Nakadori corridor and Hamadori on the Pacific.

Ibaraki offers two particularly clear visitor corridors north-east of Tokyo.

Tochigi contains several strong destinations, but they sit in separate parts of the prefecture.

Gunma stretches from the Kanto plain into mountain and hot-spring country, with Takasaki serving as the practical rail hinge.

Saitama begins just north of Tokyo but quickly changes from commuter cities to river valleys and mountain communities.

Chiba surrounds Tokyo Bay and extends deep into the Boso Peninsula, so its visitor geography is broader than the airport corridor suggests.

Tokyo is more useful to plan as a collection of neighbourhood narratives than as one enormous list of landmarks.

Kanagawa compresses a major port city, historic temple towns, bay beaches and volcanic highlands into a prefecture with several very different travel rhythms.

Niigata follows the Sea of Japan for a long distance and includes the distinct island world of Sado, so itinerary shape matters.

Toyama is shaped by the sharp meeting of Toyama Bay and the Northern Alps.

Ishikawa's most concentrated visitor experience is Kanazawa, where castle grounds, Kenrokuen, samurai streets, teahouse districts and craft institutions can be explored without long transfers.

Fukui's visitor geography is unusually easy to understand through two axes.

Yamanashi is organised by the mountains that enclose the Kofu basin and the volcanic landscape north of Mount Fuji.

Nagano is a mountain prefecture of distinct valleys, and its strongest destinations sit on different corridors.

Gifu runs from the Nobi plain into the Hida mountains, creating a clear difference between its southern towns and northern heritage landscapes.

Shizuoka stretches from the Izu Peninsula across Suruga Bay to the western shore of Mount Fuji, so its familiar attractions belong to several different corridors.

Aichi's travel story extends well beyond Nagoya's role as a transport hub.

Mie is a long prefecture whose travel areas follow the coast and the Kii mountains.

Shiga is organised around Lake Biwa, but the lake is not a single stop: Otsu, Omi Hachiman and Hikone each reveal a different relationship between water, trade and castle-town history.

Kyoto Prefecture contains several journeys that should not be collapsed into one city checklist.

Osaka rewards district-based planning rather than a collection of disconnected photo stops.

Hyogo stretches between two seas, so its highlights do not form one compact loop.

Nara Prefecture combines an easy rail-linked historic city with rural temple towns and sacred mountains farther south.

Wakayama reaches from the Kii Peninsula's sacred mountains to a long Pacific coast, and those areas need separate plans.

Tottori's small population does not make its attractions geographically interchangeable.

Shimane is long from east to west, with an additional island geography, so its heritage is understood clearly through regional corridors.

Okayama sits at a useful Sanyo rail junction, but its appeal extends beyond the station city.

Hiroshima Prefecture brings together places of remembrance, sacred island heritage and a long Seto Inland Sea coast.

Yamaguchi wraps around the western end of Honshu, with distinct eastern, central, northern and Kanmon districts.

Tokushima presents two especially clear journeys.

Kagawa is compact, yet its mainland and island experiences run on different systems.

Ehime combines Matsuyama's castle-and-hot-spring city with two very different regional corridors.

Kochi is a long Pacific prefecture whose eastern and western landscapes sit far beyond the capital.

Fukuoka Prefecture is more than the compact gateway city around Hakata.

Saga's strongest itineraries follow its craft and hot-spring geographies rather than crossing the prefecture at random.

Nagasaki Prefecture is shaped by peninsulas, bays and islands, so the capital, Shimabara Peninsula and Sasebo should be planned as different bases.

Kumamoto combines a rebuilt castle city with the immense Aso caldera, inland hot-spring settlements and the island coast of Amakusa.

Oita's hot-spring identity is only one layer of a prefecture that also includes spiritual peninsulas and historic stone towns.

Miyazaki is divided naturally between the mythic highlands of Takachiho and the long Pacific coast south of Miyazaki City.

Kagoshima's mainland, volcanic bay and islands operate as different travel systems.

Okinawa Prefecture is an island chain, and even the main island should be planned by district.
