History

Details of the new trains were officially announced in June 2017. The first train set was delivered from the Hitachi factory in Kudamatsu, Yamaguchi, in late July 2017. Originally scheduled to enter revenue service in December 2017, scheduled service entry was subsequently postponed until 11 February 2018. In late August 2022, both the 20000 and 21000 received formation stickers located in the window of each head car before the beginning of service along the Sotetsu-Tokyu Link. These stickers will also help passengers distinguish how long each set is before boarding. Set 20103 was the first to receive a larger sticker displaying the last three digits of the Ebina bound head car of the set (eg, “003”). As of late October 2022, all sets have received formation stickers.

21000 series

An order of a short version of the 20000 series was announced on 28 April 2021. These four eight-car sets will be designated as 21000 series, and are to be operated through to lines of

. The first 21000 series set entered service on 6 September 2021. In late August 2022, the 21000 sets are being given stickers located at the end of each set to help passengers tell them apart from the identical 20000 series. In addition to formation number stickers (the last three digits of the Ebina bound head end car), they were also given “8-Cars” stickers as well, all of which was completed by late October 2022. Sotetsu had also announced an additional order for 9 more 21000 sets to help expand the fleet before service to Shin-Yokohama begins. As of November 2022, two sets (21105F and 21106F) have been delivered and entered service. It is planned that one more set (21107F) will be delivered before the end of the year 2022 while the remaining sets will be delivered in early 2023.
