Copper concentrate inbound, electrolytic copper, sulphuric acid and chemicals outbound — the cargo mix at Niihama reflects the Sumitomo industrial complex it was built around. The port serves the Toyo Smelter & Refinery, one of the world's larger single-furnace copper works, on the Seto Inland Sea coast of Shikoku. Machinery and fabricated components from the Sumitomo Heavy Industries yards add breakbulk and heavy-lift volumes. Container liner traffic is marginal here; quays and handling gear are geared to bulk, breakbulk and project cargo for local industry. Road and Shikoku's rail network tie the port into the Niihama–Saijo industrial belt. For regular deep-sea container services, shippers generally turn to Kobe or Osaka across the Inland Sea.
