Surrounding municipalitiesEdit


Humans have lived in the Asahi area for at least 25,000 years. Clans gave way to a central power during the Taika Reform in 645 A.D. The Chiba clan, or branches of it, ruled the entire Shimōsa region for about 400 years from the Kamakura period. During the Sengoku period, the Chiba clan gained the protection of such powerful clans as the Odawara Hōjō clan, allowing them to get a stronger foothold of power over the area. They lost control when the Hōjō clan was overthrown in 1590 by Toyotomi Hideyoshi. After that, General Kiso Yoshimasa settled in the region. He restored the Ajito Castle, which was the inspiration for the name "Asahi." As the governor of the region, he became a popular and respected politician. When poet Nonoguchi Takamasa visited the area in 1852, he wrote a poem about the general, from which the name "Asahi," which can mean "rising sun," was taken:

"from Shinano / adoring the rising sun / he came to the eastern land / and there remains the evidence of his earthly life"

In the Edo period, various agricultural changes in the region occurred. The first was the reclamation of the "Sea of Camellias", a vast lake, which was drained into the Pacific Ocean to create the fertile Higata Hachiman-goku. The second was spurred on by the arrival of Ohara Yugaku in 1835. Ohara was an agricultural revolutionary who helped to revive agriculture in the area. During this same time, while Iioka Sukegoro was helping to develop the fishing industry, fishermen from the Kansai region moved to the area to take advantage of the bountiful fishing grounds available.[2]

The city of Asahi was founded on July 1, 1954.

On July 1, 2005, Asahi absorbed the town of Hikata (from Katori District), and the towns of Iioka and Unakami (both from Kaijo District) to create the new and expanded city of Asahi.

The city was damaged during the March 2011 Tōhoku earthquake and tsunami. Around 15 people were killed, 2,265 buildings were damaged, with 427 buildings destroyed, 716 people were left homeless, and heavy damage was done to the town's port and fishing boat fleet.[3]



The Shiosai Limited Express service stops at Asahi and Iioka stations.
