Overview
Hashira Island (Hashira-jima) is the main island of the Hashirajima group in the western Seto Inland Sea, administratively part of Iwakuni City, Yamaguchi Prefecture. Covering about 3.12 square kilometers, it sits at the center of a ring of islands including Kurahashi, Etajima, Yashiro and the Kutsuna Islands. Fishing and the cultivation of citrus and vegetables sustain the small community, and a quiet island rhythm blends here with a surprisingly rich wartime history.

History
The island's name is said to come from the idea that it was home to many deities, which in Japanese are counted with the word hashira (pillar). The Kamo Shrine on the island still enshrines thirteen auxiliary shrines within its grounds, and even more gods are thought to have been worshiped here in the past. In the modern era the waters around the island became the Hashirajima Anchoring Area of the Imperial Japanese Navy's Combined Fleet, where battleships such as Mutsu, Nagato, Fusō, Yamashiro, Hyūga and Ise once lay at anchor. In 1943 the battleship Mutsu sank after an internal explosion in nearby waters, and a memorial to the victims stands on the island.
Access
Located near 34.02°N, 132.41°E, the island is linked to a port in Iwakuni City by high-speed ferry, generally running Monday through Saturday. Because sailings are limited, check the timetable and the last departure before you go. Once ashore, walking or cycling is the natural way to explore. Confirm the latest schedule and any cancellations through official sources.
Best season
Spring to early summer, when the sea is calm, and autumn, when the citrus ripens, are the most rewarding times to visit. Clear, dry days offer the finest views of the Inland Sea's scattered islands. Summer brings vivid seascapes but strong sun, while winter can bring gusty sea winds, so dress warmly and watch the ferry status.

Did you know?
💡 Isoroku Yamamoto, commander-in-chief of the Combined Fleet, is said to have come ashore at Hashirajima, and there was apparently friendly exchange between the navy and the islanders. The Hashirajima Channel between the island and its neighbors is dotted with submerged rocks and long known as a hazardous stretch for shipping, a reminder of the island's strategic place on inland sea routes.
