Port of Akita, Maritime port in Akita, Japan

The Port of Akita is a major port on the Sea of Japan in western Akita city, covering 662.5 hectares at the mouth of the old Omono River, now the Akita Canal. Its container terminal and the adjacent Akita Thermal Power Station stand near the Nakajima pier, where a dedicated cruise passenger terminal opened in 2018.

In 727 envoys from Balhae (Bokkai) reached this harbour, and the old marine law Kaisenshikimoku listed Tsuchizaki Minato among Japan's ten greatest ports. During the Edo period it was a Kitamaebune stop supplying revenue to the Satake clan's Kubota Domain. Renamed Akita Port in 1941 when Tsuchizaki town merged into Akita city, it was designated a major port on 19 January 1951.

The port's name changed from Tsuchizaki to Akita in 1941, when the town was annexed by the city. The passenger terminal near Nakajima pier serves ferries to Tomakomai, Niigata and Tsuruga, and the port hosts Japan's first commercial offshore wind projects.

Akita Port Station closed on 1 July 2026, so the port is no longer served by train. Reach it by bus from Akita Station timed to ferry departures, or walk about 30 minutes from JR Tsuchizaki Station. Road access is via National Route 7, Prefectural Route 56 and the Akita Expressway's Akita-Kita interchange.

An observation deck nearby provides views across the entire port and bay, helping visitors understand the scale and layout of the facility. In recent years, the site has become a center for renewable energy development, with wind power installations operating offshore.
