■Setonaikai National Park 62,781 ha.:(March. 16, 1934)

This park is located in the Seto Inland Sea surrounded by four straits, which has various natural and cultural beauties. It extends for about 400 km from east to west.
The calm inland sea had been the main water-way of introducing Japanese culture and importing culture from abroad, and in fact, the areas facing to the Inland Sea had been the center of socio-economic development of Japan until 18th century. Hence there are many places of historic interest. The climate is generally mild with relatively small rainfall. White sand beach and green pine trees as well as ports and cultivated land present scenery of harmonious beauty between human and nature.
Straits or channels are well known for their rapid speed tides. Uzushio (whirlpools) at the Naruto Channel are really worth seeing in particular.
