Quick answer: Japanese curry rice (kare raisu) is a thick, mildly spiced stew of meat and vegetables served over short-grain rice. Curry reached Japan in the Meiji era through the British, and the dish first appears in Japanese cookbooks in 1872. The Imperial Navy, school lunches and instant roux blocks later turned it into one of the most common home meals.

What Japanese curry is

Kare raisu, or curry rice, is one of the most familiar dishes in Japan. It is a thick, glossy sauce made from onions, carrots, potatoes and meat such as pork, beef or chicken, ladled over a plate of steamed short-grain rice. It is usually eaten with a spoon, and a small pile of pickles sits on the side.

Compared with curries from India or Southeast Asia, the Japanese version is generally milder, sweeter and thicker. The base is a roux of flour, oil and curry spices that thickens the stew into a velvety gravy. Flavor depends on the blend, and many households stir in grated apple, honey, chocolate, soy sauce or a spoonful of ketchup to personalize it.

The dish is a standard of home cooking and casual restaurants, and it is also served at school lunches, mountain huts and train stations. Many people in Japan would name it among their favorite comfort foods, in the same breath as ramen and sushi.

From India to Britain to Japan

Curry began in India, and it came to Japan by way of the British in the Meiji period (1868 to 1912), after the country ended its long period of seclusion. Western food in general, called yoshoku, became fashionable in this era, and Japanese chefs adapted European dishes using local ingredients and tastes.

Curry first appears in Japanese cookbooks in 1872. For a time it was an upscale dish served in Western-style restaurants, and it was expensive because the spices were imported. A plate of curry was therefore treated as a special meal and a taste of modern, Western-influenced life.

The way curry arrived in Japan has a few versions. One hypothesis credits the British Royal Navy as the source of the recipe, while another points out that curry may have become common in the Japanese Navy only after it spread through civilian life. For a food with such a long history, it is normal for its origin story to include several theories.

The Navy and the roux

The Imperial Japanese Navy is often credited with shaping the dish into its modern form. Navy kitchens are said to have thickened the sauce with flour, reportedly to keep it from spilling at sea, and curry also became a regular ship meal. This stew-like texture is what distinguishes Japanese curry from thinner Indian sauces.

The tradition continues in the modern Maritime Self-Defense Force, whose ships are known for serving curry on Fridays. Galleys have their own recipes and take pride in them, and the port city of Yokosuka promotes "navy curry" for visitors who want to try the tradition in the place where it is best known.

Curry festivals take place in the naval port cities of Yokosuka and Kure, and navy-style curry is a local attraction that visitors can look for. A typical plate includes beef or chicken, potatoes, onions and carrots, with pickled vegetables on the side, which helps explain how the dish looks today.

How curry reached every home

Several developments made curry an everyday food. Domestic curry powder was made in Japan from around 1905, which lowered the price. Powdered instant roux followed in 1945, and the block form that most households use today appeared in 1950. Dropping a block into simmering vegetables made a good curry possible for any cook.

Schools added their own chapter. Curry joined school lunch menus in 1948, and it remains a favorite among children, so many adults associate it with their own childhood. A major food maker introduced a milder roux flavored with apple and honey in 1963, making curry even more popular with young eaters.

In 1968 or 1969, a company commercialized a retort-pouch curry, a ready-to-heat meal in a sealed pack that could sit on a shelf for months. By 2000, curry was reported to be a more frequent meal in Japan than sushi or tempura.

Ways to eat it

The basic plate is curry rice, but the dish has many variations. Katsu curry adds a breaded, deep-fried pork or chicken cutlet, known as tonkatsu, and the combination is popular both in Japan and abroad. Tonkatsu itself is often counted among the "three great" yoshoku dishes, along with curry rice and croquettes.

Curry udon and curry soba put the sauce over noodles in a dashi-based broth. Curry bread, or kare pan, is a deep-fried or baked pastry filled with curry, first introduced in 1927 and now a common bakery item. Omelet rice, baked curry with cheese and curry with fried vegetables are other options.

A newer style called spice curry, which started in Osaka in the 2000s, uses many spices, and some versions include dashi. It is often served with side dishes on the same plate. Regional curries also exist, from local specialty ingredients to dishes created for festivals and anniversaries.

Ordering and etiquette tips

Curry restaurants usually let customers choose the spice level, portion size of rice and toppings. Common toppings include cutlets, fried chicken, boiled egg, cheese, vegetables and sausage. Anyone who prefers mild food should start with the default level, because the spicier settings can be hotter than expected, and portions of rice can often be increased or reduced for a small difference in price. Menus with photos or ticket machines at the entrance are common and make ordering simple.

Fukujinzuke, a sweet-and-savory relish of chopped pickled vegetables, and rakkyo, small pickled scallions, are the traditional sides. They are included with the plate at many places and are meant to be eaten in small amounts between bites. The plate is eaten with a spoon, and there is no need to be formal.

For travelers with dietary needs, note that the roux often contains meat extracts, wheat and sometimes milk. Check the ingredients on the package or ask the shop, and look for vegetable-based or halal-friendly curry options in larger cities if needed, since some restaurants now offer them. Rules, menus and prices change, so check current information.

Making curry at home

Cooking Japanese curry is straightforward. Onions, carrots and potatoes are cut into bite-size pieces and simmered with meat or without it. After the vegetables soften, the pot is taken off the heat and a block of roux is dissolved into the stew, then returned to a low heat to thicken. The dish is served over rice.

Roux blocks are commonly sold in mild, medium and hot versions, and travelers can find them in Japanese grocery stores around the world. Packaged curries in pouches are another easy option. Many households add a personal touch, such as honey, grated apple or extra onions cooked slowly until golden.

Leftover curry is a favorite the next day, when the flavors have settled. It can be turned into curry udon, baked with cheese over rice or spooned into bread, so one pot can feed a family for several meals.
