# Asatō Line

The Asatō Line (阿佐東線, Asatō-sen, lit. 'Asa East Line') is a Japanese railway line connecting Kaifu Station, Kaiyō and Kannoura Station, Tōyō. Together with JR Shikoku's Mugi Line, it has the official nickname Awa Muroto Seaside Line (阿波室戸シーサイドライン, Awa Muroto Shīsaido Rain). This is the only railway line operated by Asa Coast Railway Company (阿佐海岸鉄道株式会社, Asa Kaigan Tetsudō kabushiki-gaisha). The company's name is abbreviated to the portmanteau Asatetsu (阿佐鉄). Since the line goes through a relatively sparsely populated area, it is under severe business stress, to the point where closure of the line has been proposed.
The railway company commenced operating road–rail vehicles, known as DMV (dual-mode vehicle) in Japan, on the Asato Line from 25 December 2021.
The vehicles used are 3 extensively modified Toyota Coaster minibuses, claimed to be the first in the world, which enable through service to locations without rail infrastructure. The vehicles are classed as DMV93 type [ja].
In preparation, the rail line was disconnected from the Mugi Line in summer 2019.

## History

Japanese National Railways started the construction of the eastern section of the Asa Line in 1959, proposed to reach Muroto, where it would connect with the planned extension of the western section of the Asa line from Kochi.
The first 12-kilometre (7.5 mi) section to Kaifu opened in 1973, and further construction was undertaken until work was suspended in 1980. In 1988 construction work south of Kaifu was re-started by the Asa Coast Railway Company, the then-newly founded third-sector company. The Kaifu–Kannoura section, now called the Asatō Line, opened in 1992.
The western portion of the planned Asa Line opened as the Tosa Kuroshio Railway Asa Line to Nahari in 2002. The Kannoura–Nahari section of the proposed Asa line has not been constructed. The proposed stations were None, Muroto, Kiragawa and Tosa-Hane.
Awa-Kainan Station has been transferred to Asa Coast Railway Company since 1 November 2020 for the purpose of constructing the required changeover facilities for the DMV. The railway line was suspended from 1 December 2020 with bustitution services running until the completion of the DMV facilities on 25 December 2021.

### DMV

The development of DMV started in 2011 as an alternative to traditional, more expensive, DMU trains for rail lines with limited passengers. In February 2016, Tokushima Prefecture announced its intentions of introducing DMV in commercial operations in the next 10 years.

#### Construction

On 10 January 2019, in preparation for the construction of DMV changeover facilities, the parking area and bus terminal near Kannoura Station was relocated 50 m south. On 1 December 2020, bustitution services operated by JR Shikoku Bus commenced between Mugi Station and Kannoura Station while the facilities were being constructed. On 1 February 2021, bustitution services was revised to operate from Mugi Station to Awa-Kainan Station. On 4 November 2021, the Railway Bureau of the MLIT announced the completion of safety inspections and tests of the DMV conducted on the Asato Line. As such, on 10 November 2021, Asa Coast Railway Company announced the date for the planned introduction of DMV services - on 25 December 2021, DMV services commenced operating between Awa-Kainan Station and Kannoura Station.
