Tsukumi City is located approximately 30 kilometers from Oita City, the prefectural capital. The city is located on the coast and is surrounded by abundant nature. Until 2001, there was no highway interchange, which made it inconvenient, but recently it has become possible to travel to Oita in about 20 minutes, making it a more comfortable place to live. The city's sea is a ria coastline, surrounded by mountains over 700 meters high. Furthermore, mandarin orange orchards line the slopes of these mountains. During mandarin orange season, you can see a beautiful landscape where the colors of the sea, mountains, and mandarin oranges all line the same vibrant color. The warm climate makes it an easy place to live.
