The Futtsu Tateyama Road (富津館山道路, Futtsutateyama Dōro) is a 2-laned toll road in Chiba Prefecture, Japan. It is owned and operated by East Nippon Expressway Company.

The route is officially designated as a bypass for National Route 127, however it is functionally an extension of the Tateyama Expressway. As such it is classified as a national highway for motor vehicles only with national expressway concurrency (高速自動車国道に並行する一般国道自動車専用道路, Kōsoku Jidōsha Kokudō ni Heikōsuru Ippan Kokudō Jidōsha Senyō Dōro)^[3] with the same design standard as other national expressways.

The road extends southward from the terminus of the Tateyama Expressway. It terminates at an intersection with a local road just to the north of Tateyama, a city on the Bōsō Peninsula.

The first section was opened to traffic in 1999 and the entire route was completed in 2004.^[1]
