Japan, introduced via British India during the Meiji era (1868-1912). The Japanese Navy adopted curry as a Friday tradition (to remember the day of the week on long sea voyages), and the dish spread to civilian life. The Japanese modified the British-Indian curry substantially — thicker, sweeter, milder. S&B Foods released the first ready-made curry powder in 1923, and the roux block format in the 1950s.
Japanese curry rice (kare raisu) is one of Japan's most consumed dishes — sweeter, milder, and thicker than Indian curry, served over short-grain rice with fukujinzuke (pickled vegetables) on the side. The curry roux is typically made from a block (S&B Golden Curry or Vermont Curry) that already contains the spice blend, oil, and flour thickener. The dish is simple, comforting, and reliable — the Japanese home cooking equivalent of British shepherd's pie.
Kirin Mugi Shochu (barley shochu) with cold water — the clean, slightly sweet barley spirit complements the mild, sweet curry. Or hojicha (roasted green tea) for the non-alcoholic pairing, whose toasted grain character complements the spiced sauce.
{"The roux block: S&B Golden Curry (medium hot) or Vermont Curry (mild, with apple and honey) are the authoritative standards. Mix two different spice levels for complexity","Caramelise the onion: low and slow for 20-30 minutes until the onion is deep golden and jammy — this is the flavour foundation of the curry","Grated apple or apple juice: 1 tablespoon per serving — the apple sweetness is a defining characteristic of Japanese curry","Protein: chicken thigh (boneless, cubed), or beef chuck, or pork shoulder — seared well before adding to the curry","The addition of roux: turn off the heat before adding the roux block, break it into pieces and stir until dissolved, then return to low heat for 10 minutes — adding the roux to a boiling curry causes clumping","Short-grain Japanese rice: cooked to the slightly sticky, cohesive texture that supports the thick curry sauce"}
The moment where Japanese curry rice lives or dies is the overnight rest — Japanese curry is always better the second day. The spices deepen, the vegetables soften further, and the starch from the potato thickens the sauce. If eating the same day, at least rest the curry for 2 hours after cooking. Reheat gently, thinning with a splash of water if needed.
