The former Onishibetsu Station site is, currently, the Onishibetsu Bus Terminal.
On the 1st floor, there is a Tenpoku Line archive room, and, beginning with Onishibetsu Station, signboards and tickets, timetables, etc. of the 6 stations that were in Sarufutsu Village, many items that were used are displayed.
The former Tenpoku Line (via Okhotsk Sea) commenced construction in Taisho 1st year from Otoineppu towards Wakkanai, and in Taisho 8th year, reached Hikōjō-mae (boundary with Hamatonbetsu Town), Asajino-mae, and in Taisho 9th year, Ashino, Onishibetsu, and in Taisho 11th year, via Koishi, arrived at Wakkanai, which is the terminal point.
For a long time, it became the transportation for villagers and residents of neighboring towns and villages, and also, although it had been responsible for the transportation of coal etc., it ended its operation in Heisei 1st year.
A part of the former Tenpoku Line's railway tracks was being used as a cycling road, but, because bear sighting information occurred frequently, currently it is closed.
