Tochigi Prefecture is a landlocked gateway north of Tokyo where the UNESCO World Heritage shrines of Nikko rise beneath cedar forests, cool highland onsen resorts fill the Nasu plateau, and potters still throw Mashiko-yaki by hand — a prefecture of mountains, waterfalls, and craft traditions found nowhere else in the Kanto region.
Tochigi Prefecture has a climate shaped by dramatic elevation change, from the hot, humid Kanto plain around Utsunomiya to the cool highland climate of Nikko and Nasu. Utsunomiya and the southern lowlands see summer temperatures regularly exceeding 33°C (91°F) with high humidity, while Nikko (around 600m) and Oku-Nikko/Lake Chuzenji (about 1,270m) are consistently 5–8°C cooler, and the Nasu highlands (up to 1,900m at the summit) are cooler still with heavy winter snowfall. Winters are cold across the prefecture, with the mountain areas seeing significant snow while Utsunomiya sees only occasional light snow. The prefecture lies inland, so it is less directly exposed to typhoons than coastal Kanto, but remnants still bring heavy rain and occasional flooding August–October.
