The E5 series is operated by East Japan Railway Company (JR East); it was introduced on Tōhoku Shinkansen services on 5 March 2011 and on Hokkaido Shinkansen services on 26 March 2016. A total of 59 10-car sets are on order, with three sets in service in time for the start of new Hayabusa services to Shin-Aomori in March 2011.
The H5 series, a cold-weather derivative of the E5 series, is operated by Hokkaido Railway Company (JR Hokkaido); it has been in use on Tōhoku and Hokkaido Shinkansen services since 26 March 2016. Ordered in February 2014, a total of four 10-car sets were built by Hitachi and Kawasaki Heavy Industries at a cost of approximately ¥18 billion (US$169.9 million). The first two sets were delivered in October 2014. All Hayabusa, Hayate, Yamabiko, and Nasuno services operated by E5 Shinkansen's terminate at Shin-Aomori Station, whilst Hayabusa and Hayate services operated by H5 Shinkansen's run a through service via the Hokkaido Shinkansen to Shin-Hakodate-Hokuto Station.
