Omurice is rice fried with chicken and ketchup, wrapped in a thin layer of omelet and topped with another portion of ketchup or demi-glace sauce. It is everyday home and café food, not a dish for a haute cuisine restaurant.

What is inside omurice?

Inside is rice fried with finely chopped chicken, onion and ketchup until golden. On the outside it is wrapped in a thin omelet of beaten eggs, and on top the dish is poured with another portion of ketchup or demi-glace sauce.

Who invented omurice?

There is no single author. Tokyo's 'Rengatei' had been making rice and egg fried together in a pan since 1895. Osaka's 'Hokkyokusei' in 1925 was the first to wrap ketchup rice in a separately prepared omelet — the form closer to today's omurice. Japanese reference books do not choose a winner between these versions.

Why is the omelet in omurice sometimes not wrapped but cut open on top?

This is the 'toro-toro' presentation: a half-liquid omelet is placed over the rice and cut at the table, and it spreads. This method is associated with the 'tampopo omurice' of the restaurant 'Taimeiken', created based on a scene from the film 'Tampopo' (1985) by director Itami Juzo.

How does omurice differ from an ordinary omelet with rice?

In an ordinary omelet with rice, the ingredients simply lie next to each other on the plate. In omurice, the omelet wraps the rice on the outside or is laid over it in a single layer — it is a separate, established construction of a dish with its own name, history and obligatory ketchup.

Omurice: Japanese Omelet with Rice Inside

Omurice is rice, usually fried with chicken and ketchup, wrapped in a thin omelet and topped with ketchup or demi-glace sauce. The word オムライス is wasei-eigo, glued together from the English omelette and rice: it contains no kanji at all and is written entirely in katakana. It is home and café food, not a dish of restaurant haute cuisine.

Omurice has a simple-looking formula — an omelet around rice — but behind it stands a whole Japanese category of dishes called yoshoku and a dispute over primacy between two cities. Let's look at what that category is, who first wrapped rice in an omelet and when, and why today you often see a presentation where the omelet is not wrapped but simply cut open on top.

Rice in Ketchup Inside a Thin Omelet

Omurice is rice, usually fried with chicken, onion and ketchup, wrapped in a thin omelet. It is served topped with ketchup or demi-glace sauce. It is home and café food, not a dish of restaurant haute cuisine, and it is made just as often at home as in small diners.

オムライス — a Word Entirely in Katakana

The word オムライス itself contains no kanji: it is written entirely in katakana, like an ordinary loanword. It is wasei-eigo — a Japanese combination assembled from the English omelette and rice, which does not exist in English itself: the word was invented in Japan.

洋 — значение: Western, overseas, ocean — онъёми: ヨウ — 9 штрих(ов). 洋 — 'Western, overseas; ocean': this is the key character for all of 洋食 (yoshoku) — 'Western food', the Japanese category for European dishes reworked to local taste, as opposed to 和食 (washoku), 'Japanese food'. The same character appears in 西洋 (seiyō) 'the West' and 太平洋 (Taiheiyō) 'the Pacific Ocean'. The word オムライス itself does not contain this character — it is entirely katakana.

Write 洋 along the guides — the character of the 'West' that stands behind the category 洋食, even though the word オムライス itself has no kanji.

Yoshoku: A Japanese Category for European Food

洋食 (yoshoku) is a Japanese category of dishes that took shape in the Meiji era (1868–1912), when European cuisine poured into the country and began to be reworked to local ingredients and taste. It is not the same as simply 'European cuisine in Japan': yoshoku is a direction of its own with its own dishes, which do not exist in that form in original European cuisine.

Omurice's Neighbors in the Category

Besides omurice, yoshoku includes tonkatsu, Japanese curry, korokke and hayashi rice — rice with beef stew in demi-glace sauce. Each of these dishes has its own European prototype and its own history of reworking for the Japanese table, but one thing unites them: their origin in the Meiji era and their status as everyday, not ceremonial, food.

'Rengatei' and 'Hokkyokusei': A Dispute Without a Winner

Omurice has no single author — primacy is shared between two establishments with different versions of the dish. At Tokyo's 'Rengatei' in Ginza, opened in 1895, they made a rice omelet: rice and egg were fried together in a pan, without wrapping one in the other.

'Hokkyokusei' and Rice Wrapped in an Omelet

At Osaka's 'Hokkyokusei', founded in 1922, a different construction was invented in 1925: ketchup rice is wrapped in a separately prepared thin omelet — this version is closer to today's familiar omurice. According to the restaurant's legend, the dish was created for a regular customer with a stomach ailment who ordered the same thing every day — an omelet and rice separately.

Japanese reference books do not name a winner in this dispute: 'Rengatei' came up with the very idea of combining rice with egg in a pan earlier, while 'Hokkyokusei' came up with the form familiar today, where the omelet wraps the rice on the outside.

'Toro-toro': A Presentation Where the Omelet Is Not Wrapped

'Toro-toro' is a modern way of serving in which the omelet is not wrapped around the rice but placed on top almost raw and cut with a knife right at the table: the half-liquid omelet spreads over the rice.

From the Kitchen of the Restaurant 'Taimeiken'

This presentation is associated with the 'tampopo omurice' of the Tokyo restaurant 'Taimeiken': it was created based on a scene from Itami Juzo's film 'Tampopo' (1985), where a cook pours a spreading omelet over rice. The restaurant named the resulting dish after the film, and since then this presentation has been associated with modern, 'liquid' omurice.

Omurice with a Ketchup Drawing

In a maid café, omurice is a standard menu item, and the waitress draws a heart or a message in ketchup on the omelet right in front of the guest, saying something like a spell.
