New Transit Yurikamome (新交通ゆりかもめ, Shinkōtsū Yurikamome), formerly the Tokyo Waterfront New Transit Waterfront Line (東京臨海新交通臨海線, Tōkyō Rinkai Shinkōtsū Rinkai-sen), is an automated guideway transit service in Tokyo, Japan. It connects Shimbashi to Toyosu, via the artificial island of Odaiba, a market in which it competes with the Rinkai Line. It is operated by Yurikamome, Inc., a third-sector subsidiary of Tokyo Rinkai Holdings, Inc., itself funded by the Tokyo Metropolitan Government.

The line is named after the black-headed gull (yurikamome in Japanese), a common denizen of Tokyo Bay and the official metropolitan bird.

The line was one of the two lines constructed to transport people into the Rinkai subcenter, the other line being the Rinkai Line. The Rinkai subcenter was planned to be the seventh subcenter of Tokyo as far as back in 1979. In April 1989, the subcenter was planned to have 60,000 residents and 110,000 workers by the start of the 21st century. This plan was forced to be revised upon the collapse of the asset price bubble. The opening of the Yurikamome and the Rinkai line in 1995 and 1996 was planned to be ready by the start of the World City Expo [ja] in 1996. However, the expo was cancelled by Yukio Aoshima in April 1995. On 1 November 1995, the section between Shimbashi and Ariake opened, using a temporary Shimbashi station. In the first few months of operation, ridership hovered around 27,000 passengers per day.

In 1996, the Tokyo Metropolitan Government re-zoned Odaiba from pure business and residential to also permit entertainment zones. The island provided Tokyo with a strip of livable seaside, and within one year, ridership doubled to 60,000. As more and more restaurants, shopping malls, exhibition centers and museums opened, traffic continued to grow. On 22 March 2001, the current Shimbashi station opened and the temporary station closed. Shiodome Station opened on 2 November 2002. On 27 March 2006, the section between Ariake and Toyosu opened and stations adopted letter and number codes based on Tokyo Metro.

On 16 March 2019, two stations were renamed: Fune-no-kagakukan became Tokyo International Cruise Terminal, and Kokusai-tenjijō-seimon became Tokyo Big Sight.

There was an unrealized plan to extend the line to Kachidoki Station from at least 2000, although this plan was not in the 2016 list of considered transit routes.

The Yurikamome is Tokyo's first fully automated and driverless transit system, controlled entirely by computers with no drivers on board. However, the line is not the first fully driverless transit line in Japan, as the Nagoya Municipal Subway tested the system in 1960, the driverless technology was used during the Expo '70, and Kobe's Port Liner opened in 1981 before the Yurikamome. The trains run with rubber-tired wheels on elevated concrete track guided by the side walls.

The line uses Mitsubishi Heavy Industries rubber-tired "Crystal Mover" technology. As of 8 April 2021^[update], the following train types are used on the line, all formed as six-car sets.
