Containers, vehicles and forest products move through Tomakomai Ko, the principal maritime gateway for Japan's northern island of Hokkaido. Sheltered behind breakwaters on the North Pacific, the port is split into a western and an eastern basin and handles roughly 500,000 TEU a year across two terminals with five container berths. Alongside boxes, it manages heavy RoRo and ferry traffic: Taiheiyo Ferry and MOL Sunflower link Tomakomai with Sendai, Nagoya and the greater Tokyo area, carrying both accompanied and unaccompanied trailers. The surrounding industrial belt of petrochemical and paper plants feeds steady breakbulk and project cargo. Road and rail corridors connect the quays to Sapporo and Hokkaido's agricultural interior, making the port the island's chief inbound and outbound point for consumer goods, machinery and chilled food. Customs clearance and most international container feeders are consolidated through the major ports of Tokyo and Yokohama. Shippers needing direct transpacific calls typically pair Tomakomai with transhipment at Tokyo or Yokohama.
