A pre-series train, consisting of one nine-car set (set S101) and one three-car set (set S201), was delivered in July 2015 for performance testing. These trains replaced the older E351 series EMUs used on Super Azusa (Now Azusa) limited express services on the Chūō Main Line between Shinjuku in Tokyo and Matsumoto in Nagano Prefecture. Originally intended to enter revenue service in spring 2016, the first trains entered service on 23 December 2017.
