History

A four-car pre-production set was delivered from Fuji Heavy Industries in November 1998 for evaluation and testing. The first production trains were introduced on Super Sōya services between  and  from the start of the revised timetable on 11 March 2000.

New KiHa 261-1000 series 5-car sets were introduced on Super Tokachi services between  and  from October 2007.

A further 28 KiHa 261 series vehicles were delivered from 2015 onward, and these are not equipped with tilting capability.

From December 2015 until the end of 2017, the KiHa 261-1000 series fleet were gradually repainted into a new livery with white front ends, yellow front-end gangway doors, and a purple bodyside stripe.

KiHa 261-5000 series 
On 17 October 2019, JR Hokkaido announced plans to introduce two new KiHa 261-5000 series 5-car sets. They each feature external colour schemes inspired by the hamanasu and lavender flowers, which, according to JR Hokkaido, are prominent throughout Hokkaido.

Car 1 is designated as a lounge car, featuring window-facing seats and transverse seating bays with tables. Cars 2 through 5 are ordinary-class cars, featuring 2+2 abreast seating throughout.

The "Hamanasu" set was built at Kawasaki Heavy Industries' Hyogo factory, and was delivered to JR Hokkaido in July 2020. It entered revenue service on 17 October of that year. The "Lavender" set was delivered from the same factory in January 2021 and entered revenue service in May of that year, although it was originally intended to enter service in April.
