Tochigi is a rural part of Japan with hot springs, mountains and plenty of hiking. Tochigi lies on the Tohoku northern line of the Shinkansen and highway. Ustunomiya is the largest city.
Unsurprisingly, this rural part of Japan speaks almost exclusively Japanese, with a few exceptions, like the immediate area around Nikko's sites. One can make themselves understood certainly, and people will know a charming smattering of English. Young people especially will know a little more than the average person, thanks to the education system's inclusion of English starting in elementary school. But don't expect to explain your problems in detail to someone and have them be able to help you. One will also occasionally find people who speak Korean, as well.
The temples of Nikko are undoubtedly the star attractions of Tochigi.
Nasu is a popular tourist destination. It features hot springs, restaurants, shopping, themed attraction and at the very top Mt. Nasu offers great walking. You can ski here in winter. The emperor has a house here that was recently opened to the public.
Those with spare energy can do hiking or skiing in the mountains. Those without can recharge in the numerous hot springs.
You can go horse riding. You can ride in a wide ground. Also you can feel a part of the beautiful scenery and enjoy the clean air.
Kanpyō （干瓢）is a well-known Tochigi product, made from a gourd called yūgao (夕顔, lit. "evening face"). The gourd is thinly sliced and dried, then reconstituted in water when used. The end product is a brown pickle-like substance, perhaps most often encountered as a filling in sushi rolls. Tochigi produces 90% of Japan's kanpyō and is also Japan's largest producer of strawberries.
Gyouza is a famous food in Utsunomiya, Tochigi. These are dumplings with a variety of ingredients, most commonly garlic and pork. There are a lot of tasty Gyouza shops in Utsunomiya.
