Japan in December: Winter Weather, Holidays and Best Places

Hokkaido

Hokkaido is not a single-city extension of a Japan itinerary but an island-sized region whose landscapes, weather and transport gateways reward deliberate planning. Sapporo is an excellent arrival base, yet the 50-place Hokkaido list also reaches Otaru and the Shakotan side of central Hokkaido, Asahikawa, Biei and Furano in the north-central area, Hakodate and Matsumae in the south, and the wetlands, lakes, drift-ice coast and World Heritage nature of eastern Hokkaido. Choose one or two regional arcs, use different arrival and departure airports when possible, and leave enough time for weather to change the plan.

Miyagi

Miyagi is easy to enter and surprisingly difficult to reduce to one base. Sendai is a compact Tohoku hub with urban culture and Date history; Matsushima and Shiogama form a rail-and-boat landscape around an island-filled bay; the Miyagi side of Zao rises to a volcanic crater reached only in the open-road season; Naruko links distinctive hot springs with a gorge and rural rail line; northern Miyagi spreads across rice country and the Kurikoma mountains; and the Sanriku coast is a long chain of fishing ports, memorial landscapes, islands and rebuilt communities. This guide turns those differences into a practical journey, separating frequent city transport from seasonal buses, BRT services, mountain roads and coastal driving while leaving room for weather and local life.

Tokyo

Tokyo Prefecture is larger and more varied than the familiar skyline suggests. Its 23 special wards contain temple districts, palace grounds, museums, markets and contemporary neighborhoods; western Tama adds foothills, rivers, historic towns and mountain access; the prefecture also includes distant islands that require separate planning. For a first visit, build one coherent urban day, then use additional days to explore one district deeply rather than racing across the map.

Nagano

Nagano is not one destination but a highland prefecture of separate valleys, historic corridors and mountain gateways. A Shinkansen can reach Nagano City or Karuizawa quickly, yet the final approach to Togakushi, Jigokudani, Kamikochi, the Kiso post towns or an alpine trail may depend on a bus with limited departures, a seasonal ropeway or a road that closes in winter. The reward for accepting that geography is an unusually varied journey: early worship at Zenkoji, black-timbered Matsumoto Castle, clear Azusa River water in Kamikochi, Nakasendo streets in Narai and Tsumago, resort architecture in Karuizawa, snow-country hot springs and high ridgelines. This guide organizes the existing fifty-place Nagano database into five realistic regional modules. It is written for travellers who want practical depth—when to stay overnight, when luggage becomes a problem, why a mountain forecast matters, and which areas should not be forced into the same day. Always check official opening, trail, wildlife, road and transport notices before departure.

Hyogo

Hyogo is often crossed rather than understood: a Shinkansen stop at Kobe or Himeji, a baseball pilgrimage to Koshien, or one winter night in Kinosaki. Yet the prefecture is a compact lesson in how Japan changes between two seas. The Kobe-Hanshin corridor is dense, urban and rail-rich; Himeji anchors historic Harima; Tamba holds castle towns, farms and pottery valleys; Tajima descends through mountains to the Sea of Japan; and Awaji Island looks south across the Seto Inland Sea. A satisfying trip therefore uses more than one base and more than one transport mode. This guide builds a six-region journey with realistic transfers, seasonal cautions, locally grounded food choices and official links to check immediately before travel.

Nagasaki

Nagasaki Prefecture is an archipelago-facing journey, not a single city break. Nagasaki City, Sasebo and Kujukushima, the Shimabara Peninsula and Unzen, the Goto Islands, Iki, and Tsushima each have their own gateway and workable trip length. Rail, tram and highway bus make the two mainland cities comparatively easy; peninsula buses, mountain roads, flights and ferries require separate planning. The islands are not stepping-stones on one convenient loop, and a line on the map is not a promise of a same-day connection. Wind, waves, fog, typhoons, winter weather and timetable revisions can change a trip. The best plan gives each region an overnight, protects the final connection, and treats churches and Christian heritage settlements as living communities rather than scenery.
