A Brief History of Tosashimizu

The area of Tosashimizu was once part of ancient Tosa Province. During the Edo period (1603-1868), the Yamauchi clan ruled this area from their castle in Kōchi.

After the Meiji Restoration in 1868, Japan created a new system for towns and villages. On April 1, 1889, the village of Shimatsu was formed. It later changed its name to Shimizu and became a town in 1924. On August 1, 1954, Shimizu joined with three nearby towns: Shimokawaguchi, Misaki, and Shimokae. Together, they formed the city of Tosashimizu.

Tosashimizu's Economy and Industries

The biggest industry in Tosashimizu is fishing, especially deep-sea fishing. A special seafood product called Sōdabushi is very important here. It's locally known as mejikabushi. Tosashimizu produces about 70% of all sōdabushi in Japan. It's made from frigate mackerel, similar to how katsuobushi is made. Local fishermen also sell blue mackerel, which they call "Tosano shimizusaba."

The Osaka Aquarium Kaiyukan has a special research center in Tosashimizu. It's called the Osaka Aquarium Biological Research Institute of Iburi Center (OBIC).

Fun Places to Visit in Tosashimizu

Cape Ashizuri: A Natural Wonder

The coastline of Tosashimizu stretches for 70 kilometers. It attracts over 800,000 tourists every year. Ashizuri-Uwakai National Park includes Cape Ashizuri, the largest peninsula in the area. Tosashimizu is the closest city to this cape, which sticks out into the Pacific Ocean.

Cape Ashizuri is 80 meters (262 feet) above sea level. The peninsula is covered with subtropical plants like camellia and holm oak. You can also see colonies of Livistona palms. The sea here is a great place for fishing, especially for skipjack tuna. Cape Ashizuri is known as the southernmost point on Shikoku island.

The Tatsukushi area has interesting rock formations made of sandstone and mudstone. A famous gate-shaped rock, Hakusandōmon, is on the west side of the cape. There's also the Tōjindaba Site, a prehistoric place with a stone circle, located on a hill near Cape Ashizuri.

Birthplace of Nakahama Manjirō

On the western shore of the Ashizuri peninsula is the village of Nakanohama. This is where Nakahama Manjirō was born. He was one of the first Japanese people to travel to the United States. In 1841, Manjirō, a young fisherman, was shipwrecked. He was rescued by Captain William H. Whitfield from Fairhaven, Massachusetts.

Captain Whitfield brought Manjirō back to Fairhaven and New Bedford. Manjirō lived there for several years before returning to Japan. Because of this history, Tosashimizu became sister cities with Fairhaven and New Bedford in 1987. Manjirō became famous as John Manjirō after a novel was written about his life.
