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 is one of Japan's safest prefectures. Violent crime is extremely rare. The primary risks for travellers are natural hazards: volcanic activity at Mount Nasu (Chausu-dake), winter mountain road conditions in the Nikko and Nasu highlands, wild animal encounters on forest trails, and typhoon-season flooding along mountain rivers.

- Water safety
- Detail
- Tap water is safe to drink throughout Tochigi. Onsen water is mineral-rich and sometimes acidic (especially at Nasu-Yumoto); do not drink it unless a sign specifically indicates it is safe.
- Topic
- Pharmacies
- Detail
- Matsumoto Kiyoshi, Sundrug, and Tsuruha Drug pharmacies in Utsunomiya are well-stocked; smaller towns like Nikko and Nasu have limited pharmacy options. Staff may not speak English — bring a translation app. Prescription medicines from overseas may require a Japanese prescription.
- Topic
- Insect hazards
- Detail
- Japanese giant hornets (osuzumebachi) are present in mountain forests May–October. Do not approach nests. In case of a sting: seek emergency care immediately. Tick-borne disease risk is present in forested areas — use insect repellent and check for ticks after hikes.
- Topic
- Heat and altitude
- Detail
- Utsunomiya and the Kanto plain lowlands can be hot and humid in summer (regularly above 33°C/91°F); Nikko highlands and Nasu highlands are markedly cooler by 5–10°C. Carry sun protection — UV is stronger at altitude around Lake Chuzenji and Nasu.
- Topic
- Onsen safety
- Detail
- Some Nasu-Yumoto and Shiobara onsen waters are acidic or sulphuric — limit initial soaks to a few minutes and build up gradually. Persons with heart conditions, high blood pressure, or open wounds should consult a doctor before bathing. Do not soak alone in private or remote outdoor onsen, particularly at altitude.
