Design

Two seven-car trainsets are being built by Nippon Sharyo, with the design overseen by Noriaki Okabe Architecture Network.[2] The total cost of the two trains will be approximately 4 billion yen.[2] The trains are finished in a "Rose vermillion" livery with "Romancecar vermillion" and grey body side stripe.[3]

Individual cars are equipped with electro-hydraulic full-active suspension to minimize lateral vibration.[4]

The 70000 series won the 2019 Blue Ribbon Award.[5]

The trains primarily operate on the Odakyu Odawara Line between Shinjuku in Tokyo and Hakone-Yumoto in Kanagawa Prefecture.[1]

The trains are formed as seven-car sets of 20 m bogie cars, as follows, with four motored ("M") cars and three non-powered trailer ("T") cars, and car 1 at the western (Hakone/Odawara) end.[6]
