Takaoka (高岡郡, Takaoka-gun) is a district located in Kōchi Prefecture, Japan.
The Shimanto River, that disperses further west in the Hata district, has its source in Tsuno.
Like most rural areas in Kochi, transport is limited for residents and visitors without private vehicles.
The JR Dosan line that runs from Kochi passes through Hidaka, Sakawa and Kure (Nakatosa) on the way to Kubokawa (Shimanto Town).
Local buses do operate within areas of Takaoka, such as a regular but infrequent set of routes servicing Sakawa, Ochi and Niyodogawa.
