Tatebayashi is a city surrounded by major rivers, Watarase River to the north and Tone to its south, with many ponds, such as Morinji Pond, scattered here and there. This wealth of nature has enabled the city to run "Tatebayashi City Tsutsujigaoka Park," where you can enjoy Mother Nature's beauty. In the anime's story, the hero and other characters began considering a travel to the South Pole in this park. It is one of the crucial sites in the story. The park features numerous azalea trees of many different kinds, including the one called "Koto-no naishi iai azalea," whose estimated age is some 800 years. The park hosts an "azalea festival" from early April to early May every year to let visitors appreciate beauty of the flowers.
