The Odakyu 10000 series HiSE (小田急10000形 Odakyū 10000-gata) (High-decker/High-grade/High-level Super Express) was an electric multiple unit (EMU) train type operated by the Odakyu Electric Railway on Romancecar services in the Tokyo area of Japan between 1987 and 2012.
The 10000 series HiSE operated mainly between Shinjuku Station in Tokyo and Hakone-Yumoto Station (about 88 km).
Sets number 2 and 3 were transferred to the Nagano Electric Railway in 2006 after being converted to 4-car 1000 series sets at Nippon Sharyo.
The two remaining 10000 series HiSE sets were withdrawn by Odakyu on 16 March 2012.
