Insider tip — Maizuru is northern Kyoto Prefecture's major port on the Sea of Japan — and one of modern Japan's most emotionally resonant places. Between 1945 and 1958, Maizuru served as Japan's primary repatriation port: 660,000 soldiers and civilians returned through this harbor from China, Korea, Manchuria, and Siberia after WWII. The Maizuru Repatriation Memorial Museum preserves this history. Hikari no Yu (Bath of Light) offers a warm welcome in a port city that welcomed home those who thought they might never return.
