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 portmandeau 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.

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.

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.

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.^[1] On 1 December 2020, bustitution services operated by JR Shikoku Bus commenced between Mugi Station and Kannoura Station^[2][3] 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.^[4][5]

Services commence at Awakainan Bunkamura (Awa-Kainan Cultural Village) bus stop then proceed to Awa-Kainan Station to enter the railway line, travel south along the railway line to Kannoura Station, exit the railway line then proceed north to terminate at Michinoeki Shishikui Onsen (Roadside Station Shishikui Onsen) bus stop. The journey is 15 kilometres (9.3 mi) long and takes 34 minutes to complete.

On weekends and holidays, 1 trip per day extends to/from Cape Muroto stopping at 4 stops as indicated below. The journey is 50 kilometres (31 mi) long and takes 1 hour 30 minutes.

Operation commenced on December 25, 2021. 13 round trips per day were operated on weekdays, while on weekends & holidays there were 11 round trips as well as the 1 round trip to/from Cape Muroto which departed Awakainan Bunkamura at 10:57am, returning at 1:35pm.^[6][7]

On March 11, 2023, a revised timetable was introduced which reduced the number of trips on Tuesdays and Wednesdays from 13 to 8, and reduced from 11 to 10 on Weekends/Holidays. The round trip to Cape Muroto remained.^[8]

On March 16, 2024, a revised timetable was introduced which reduced the number of trips on all weekdays to 8. The number of weekend trips was unchanged.^[9] The first trip on all days departs Michinoeki Shishikui Onsen at 6:10am and the last trip terminates there at 5:38pm. The weekday timetable can be operated with one vehicle, while the weekend/holiday timetable requires two vehicles with some trips operating only 12 minutes apart. The weekend/holidays Cape Muroto trip departs Awakainan Bunkamura at 11:58am and arrives at Muroto (Uminoeki Toromu) at 1:28pm, departing there at 1:52pm and arriving back at Awakainan Bunkamura at 3:23pm.

Due to the limited capacity of the DMV (16 seats, 0 standing), the operator suggests that seats be booked in advance.[1] Bookings can be made in person at Shishikui Station or at Japan Bus Online (in English). Service status and bookings are available (in Japanese) at J-Bus.
