On a cape of rocks like stacked pillars,a beacon is said to have lit the night sea.

The city describes Cape Ogon as a coast lined with rugged rocks that look like stacked pillars. The Hiyoriyama beacon site on the high ground is a city-designated cultural property. Wood was lit at night to light the sea, and passing ships are said to have known their voyage was safe by the flames.

03 ／ Rumoi River

A winding river was reroutedby a new channel straight to the sea.

According to a Ministry of Land, Infrastructure, Transport and Tourism document, the Rumoi River wound widely through the lower town. To expand Rumoi Port, a new channel was cut from 1917 to 1923, sending the river to the Sea of Japan without passing through the port. The filled-in old riverbed became commercial and residential land.
