Sasebo was a fishing village of about four thousand people when the Imperial Navy chose its harbour in the 1880s — deep, sheltered, and pointing at the Asian mainland. Within a generation it was one of Japan’s four naval districts, and it has been a navy town ever since, for two different navies.
The harbour is the reason: a long, narrow, deep inlet screened by islands, on the side of Kyushu facing Korea and China. The Navy established a district here in 1889, and the town grew around it at a speed that left almost nothing of what came before.
Docks, arsenals, a rail link and a water supply. And, out at Hario, three reinforced concrete radio towers completed in 1922 — 136 metres tall, built to reach submarines across the Pacific, and among the tallest concrete structures in the world at the time.
They are still standing. The signal that carried the order to begin the attack on Pearl Harbor is widely said to have been relayed from here, and the towers are open to visit, empty and unnervingly quiet.
On 29 June 1945 the city was firebombed, and about a third of it burned. The base survived the war; the town largely did not.
From 1946, the United States Navy has operated Fleet Activities Sasebo from the same harbour, and Japan’s own Maritime Self-Defense Force is based here too. Two navies, one inlet, and a city that has organised itself around both for eighty years.
This is why the arcade sells American-sized portions, why the burger exists, and why English is more common on signage here than in comparable Kyushu towns.
Grey hulls, from the waterfront and from the harbour cruise that runs at weekends past both fleets. The Sasebo Naval Memorial Museum covers the history and is free.
The base itself is not open, and photography near the gates is not welcome. That is worth knowing before you point a lens at anything.

Take the weekend harbour cruise past both fleets, and give the free naval museum forty minutes.
Because of the harbour — a long, narrow, deep inlet screened by islands on the side of Kyushu facing Korea and China. The Imperial Navy established a district here in 1889 when Sasebo was a village of about four thousand people, and the US Navy has operated Fleet Activities Sasebo from the same water since 1946.
Not inside it, and photography near the gates is not welcome. You can see the grey hulls from the waterfront and from a harbour cruise that runs at weekends past both the Japanese and American fleets, and the free Sasebo Naval Memorial Museum covers the history.
