Source-derived summary

The ET122 is a diesel multiple unit (DMU) train type operated by the third-sector railway operator Echigo Tokimeki Railway (ETR) on the Nihonkai Hisui Line between Naoetsu and Ichiburi in Niigata Prefecture since operations on the line were transferred from West Japan Railway Company (JR West) on 14 March 2015. Built by Niigata Transys and based on the JR West KiHa 122 series DMU design, the fleet consists of a total of eight single-car units.

The fleet consists of six standard cars, numbered ET122-1 to ET122-6, and two special-event cars, numbered ET122-7 to ET122-8.

Both types have a wheelchair space at one end and a universal access toilet.

A two-car resort train classified ET122-1000 (cars ET122-1001 + ET122-1002) and branded Setsugekka (雪月花; lit. "Snow, Moon, Flowers") was built by Niigata Transys and delivered in March 2016. This trainset entered service on 23 April 2016, operating mainly at weekends.

Editorial analysis

Why this record matters

“ET122” is worth following because a concise public description often conceals a longer documentary argument. Here, ET122, Japanese and diesel provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 29, 2026. The linked authority identifier is Q18702123. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 1001, 1002 and 1000.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
