Insider tip — Nobori Kumo, the rising cloud spring, serves Yokosuka City on the Miura Peninsula where the Japan Maritime Self-Defense Force headquarters and the US Naval Base Yokosuka — the largest US naval installation in the Pacific — create the most militarized coastal geography in Japan. Yokosuka is famous for Yokosuka Navy Curry, a thick beef curry introduced by the Imperial Japanese Navy in the Meiji era to prevent beri-beri among sailors — a recipe so carefully preserved that the city issues official certification to restaurants serving the original Navy formula unchanged since 1908.
