Asahi’s hot spring resources were already attracting attention as a tourist destination during Japan’s period of rapid economic growth. In 1970, the area was listed in the Japan Travel Bureau’s guidebook 1,300 Hot Springs Across Japan under the name Asahi Onsen.
The source temperature was approximately 27°C at the time, close to the temperature recorded today. The spring has therefore been utilized as a local natural resource for many decades.
In October 1974, a public resort facility known as Kanpo no Yado Asahi opened in the area. From 1992, it was also made available to general guests, helping establish the destination as a hot spring resort not only for local residents but also for travelers from outside the region.
The facility later became part of the area’s broader accommodation and tourism infrastructure, contributing to the development of Asahi Kujukuri as a seaside resort destination.
The nearest major railway station is Asahi Station on the JR East Sobu Main Line. From the station, visitors can use local transportation to reach the hot spring area and nearby coastal attractions.
The Inugō-go Asahi Route connects Tokyo Station with destinations including Higata, Asahi, Asahi Central Hospital East, Kaijo, Iioka, Choshi Station, and Inubosaki. Services are operated by Chiba Kotsu and Keisei Bus.
The Choshi–Chiba/Makuhari route also connects destinations such as the Driver’s License Center, Kaihin-Makuhari Station, Chiba-Chuo Station, and Chiba Station with Higata, Asahi, Kaijo, Iioka, and Jinya-cho. The source information notes one round trip on weekdays.
When traveling by car, the Matsuo-Yokoshiba Interchange on the Choshi Renraku Road provides convenient access to the Asahi area.
From there, the Kujukuri Beach Line (Chiba Prefectural Route 30) provides easy access to the hot spring area and many attractions along the coast.
