The Kyoto Municipal Subway 20 series (京都市交通局20系電車) is an electric multiple unit (EMU) commuter train type operated by the Kyoto Municipal Subway in Kyoto from March 2022.
The 20 series was introduced in 2022 with nine 6-car sets. These sets are replacing the oldest of the existing 10 series in service since 1981. Each vehicle costs around ¥200 million (US$1.82 million) to construct.[1] Power consumption on these trains is projected to be about 30 percent less than the 10 series counterparts.[2]

History
The design of what would become the 20 series was announced by the Kyoto Municipal Transportation Bureau on 29 March 2019 after a public vote.[5]
The first set was delivered in 2021,[6] and test runs commenced in October of that year.[7] A total of 9 sets, 54 cars, are to be built by Kinki Sharyo.
The 20 series made its first trips in revenue service on the Karasuma Line on 26 March 2022;[2] in addition, the fleet began service on the Kintetsu Kyoto and Nara lines from 12 and 17 April of that year, respectively.[4] A second trainset entered service on 21 June 2022.[8] Deliveries are expected to last until 2025.[3]
To commemorate the type receiving the 2022 Good Design Award,[9] a third set, scheduled to enter service on 18 November 2022,[needs update] was built with commemorative "Kitayama Log" plating. Such plating is due to be applied to the pre-existing fleet as well as subsequent sets.[10]
The 20 series received the 2023 Laurel Prize, presented annually by the Japan Railfan Club.[11]
A fourth set will enter service on 27 September 2023.[12]
