Agriculture, forestry and fishery products and ecosystem
Characteristic agriculture, forestry and fishery products and the diverse ecosystem

As a source of nutrients for phytoplankton and seaweed, this spring water supports the rice paddy agriculture and coastal fishing in addition to nurturing the diverse ecosystem.

Agriculture, forestry and fishery produce brimming with regional characteristics
This area didn’t partake in large-scale rice paddy farming so in order to maintain their livelihood residents needed to cultivate a crop that complemented wetland rice. In the past, many farming households combined rice paddy farming with log wood cultivated Shiitake production, but these days there are many commodities being produced such as beef, Welsh onions, small Welsh onions, and greenhouse-grown Mikan fruit. There are many characteristic products, and in particular the Shichitoui crop production area in Kunisaki City is the only production region in the country. In addition to this, there are a variety of agriculture, forestry and fishery industries developing in Oita Prefecture such as the Oita Prefecture specialty Kabosu lime, and the indigenous species such as Mitori beans and Oben persimmons that have taken root in this region.
