Swan flying area (new embankment/Sango Bridge)

Swans begin flying around the new embankment and Sango Bridge (Kitakami River) from around late October, and stay until around April of the following year. More than 1,000 swans spend the winter here each year, bringing a sense of peace to visitors. The number of visitors is the highest in the prefecture. To get to the new embankment, take the JR Tohoku Shinkansen Kitakami Station and get off at the Iwate Prefectural Transportation Kitakami Noh High School/Hikashita Line Minami Junior High School bus stop.

Natsuyu Onsen

Natsuyu Onsen is a deep secluded hot spring located at the northern end of Kurikoma Quasi-National Park, overlooking the Natsuyu Valley surrounded by virgin beech forest. The discovery and use of hot springs has a long history, and a medicinal book from the Edo period described it as ``the most famous hot spring in the Nanbu Domain.'' In the hot spring rankings published in Edo and Kyoto at the time, it was ranked as the highest ozeki in the east, along with Hongu Onsen in Kishu, the ozeki in the west. It is still one of the ``100 famous hot springs in Japan''.
