How a British naval import became Japan’s most beloved national comfort food
In short: Introduced by the British in the 19th century, curry underwent a radical transformation in Japan. By thickening the sauce with flour and pairing it with sticky rice, the dish evolved from a luxury Western-style meal into a ubiquitous, home-cooked staple that now outsells sushi and tempura in daily consumption.
Curry first entered Japan during the Meiji period, appearing in cookbooks by 1872. Initially classified as yōshoku, or Western-style food, it was a high-end luxury served in elite restaurants. Its transition to a national dish was fueled by domestic production of curry powder in 1905 and the later invention of instant roux. By 1945, powdered mixes were available, followed by block-shaped roux in 1950, which simplified preparation for home cooks. The 1968 launch of Bon Curry, the world’s first retort pouch meal, further cemented its status as a convenient, shelf-stable favorite.
The dish's military roots are significant. While often linked to the British Royal Navy, some researchers argue the Imperial Japanese Navy adopted curry from the civilian sector rather than the other way around. Regardless of its origin, it became a weekly staple aboard naval ships to combat beriberi, a thiamine-deficiency condition caused by a diet heavy in white rice. This tradition persists today in the Japan Maritime Self-Defense Force, where ships unofficially compete to craft the best recipe for their Friday curry service.
Japanese curry is distinct from its Indian ancestors. It is typically sweeter, thicker, and milder, often incorporating ingredients like apples and honey—a trend popularized by the 1963 release of Vermont Curry. While traditional curry rice remains the standard, the dish has spawned numerous derivatives, including curry udon, curry bread, and the breaded cutlet dish known as katsu curry. In recent years, the trend has shifted again with the rise of spice curry in Osaka, which emphasizes complex spice blends and dashi-based broths, reflecting the dish's ongoing capacity for reinvention.
