Operated by the Tokyo Tama Intercity Monorail Co., Ltd., the double tracked, 16.0 km (9.9 mi) monorail line carries passengers between the suburban cities of Higashiyamato and Tama via Tachikawa, Hino, and Hachiōji in 36 minutes.

Tourist venues along the line include Tama Zoo and Keio Rail-Land (a railway museum), both adjacent to Tama-Dōbutsukōen Station.

One route is an extension north from the current terminus at Kamikitadai to Hakonegasaki Station on the Hachiko Line.

[4] The seven-station extension will be 7 km (4.3 mi) long and is projected to cost ¥80 billion (2021) (US$728.93 million).

The expansion had also been considered to be run as a separate light rail transit line, but was ultimately abandoned in December 2016 citing topographical and technological constraints.
