Tomioka silk mill, or Tomioka Silk Factory, built in 1872, was the first of its kind in Japan. The publicly owned brick building was designed by Paul Brunat, a French engineer.

Nukisaki Shrine is a moderately well-known shrine in Japan because of its design. Whereas a shrine's main building area is usually approached over flat ground or by an ascent, Nukisaki Shrine is entered via a descending flight of stone steps. During the New Year's holiday, an estimated 100,000 people visit Nukisaki Shrine to pray for happiness in the year ahead. This is the largest gathering of its kind in Gunma.
Gunma Safari Park was the 5th safari park built in Japan and the 1st built in eastern Japan. The park's approximate 1000 animals consist of around 100 species.
