The 681 series (681系, 681-kei) is a dual-voltage electric multiple unit (EMU) train type operated by West Japan Railway Company (JR-West) and Hokuetsu Express on limited express services in Japan.


681-0 series[edit]

Four six-car sets (T01–T03, T06) and five three-car sets (T11–T13, T15, T17) are used on Thunderbird services. These trains feature "Thunderbird" branding. Also four six-car sets (W01–W04) and four three-car sets (W11–W14) are used on Hakutaka services. These trains feature "White Wing" logos.[3]

From February 2015, Hakutaka W sets began being repainted into the same livery as 683 series trainsets used on Shirasagi services, with thin blue and orange lines below the window band.[4]

681-1000 series[edit]

The pre-series six-car set (T18) and one three-car set (T07) are used on Thunderbird services.[3]

681-2000 series[edit]

Two six-car sets (N01–N02) and two three-car sets (N11–N12) are used on Hokuetsu Express Hakutaka services. These trains feature "Snow Rabbit Express" logos.[3]


Future developments[edit]

All of the 681 series trainsets used on Thunderbird limited express services are scheduled to undergo a programme of refurbishment from autumn 2015 until the end of fiscal 2018.[5]
