Rice dishes ── Donburi (rice bowls)
Oyakodon
chicken and egg rice bowl
Chicken thigh and onion simmered in broth, bound with egg, and served over rice. Said to trace to a Nihonbashi Ningyocho game-fowl restaurant, where diners began binding leftover hot-pot meat and broth with egg.
- Origin: Tokyo Chuo
What it's made of
Chicken thigh and onion simmer in a sweet-savory dashi broth until the meat softens, then beaten egg is poured over and left just short of set. The broth's aroma comes first, followed by the richness of chicken fat meeting egg, and as the still-runny yolk breaks into the rice with each bite, a scattering of mitsuba leaf cuts through the sweetness at the end.
How it's made
Chicken and onion cook down in a warishita of dashi, soy sauce, and mirin, then beaten egg is swirled in from the center outward in a wide circle. The trick, it's said, is pulling it off the heat while the egg is still soft — overcooking tightens the curd — so many shops let residual heat finish the set before it goes over rice, topped at the end with mitsuba for color and scent.
Why it took this shape
One account traces it to a game-fowl restaurant in Tokyo's Nihonbashi Ningyocho, where customers began binding the leftover meat and broth from a chicken hot pot with egg and eating it over rice. Originally a delivery-only dish, its form — portable by hand, holding its flavor even once cold — suited a busy merchant district. Chicken and egg, parent and child from the same bird, gave the dish the name it still carries.

- Station food and ekiben (station bento)Where and when to find ekiben (station bento) before it sells out, etiquette for eating on board, how standing soba and udon stalls work, and where to find souvenirs sold inside the station.
- Roadside stations, direct-sale stands, and marketsHow to enjoy buying food near where it's produced, visiting and shopping at morning markets and fish markets, what to expect at farm stands, and finding local food at roadside stations (michi-no-eki).
Dishes in the same style
- Aburafu DonDeep-fried wheat gluten, shaped into a log, is simmered in a sweet-savory broth and set with egg over rice, katsudon-style — a Tome City bowl said to trace to a tofu shop's shelf-stable gluten product, later turned into a bowl dish by a local innkeeper.
- Aizu Sōsu KatsudonAizu's sauce katsudon, doused in a thick sweet-savory sauce. Its origin has several competing accounts, none settled, but all point to it being refined through everyday improvisation on Taisho-era Western food.
Ingredients and dishes from this land
Also from Tokyo
- Abura SobaNo broth is poured at all — noodles are tossed in a soy-and-sesame-oil tare pooled at the bottom of the bowl, said to have started at shops in the Musashino area in the late 1950s, with vinegar and chili oil stirred in partway through.
- Ajitsuke NoriSheet nori brushed with a soy-and-sugar seasoning and toasted crisp, said to have been devised as a gift for an imperial visit to Kyoto in the Meiji era. Its snap gives way to a burst of flavor and aroma.
- Anago ZushiConger eel, simmered sweet and savory, is laid over sushi rice and brushed with a reduced glaze called tsume — a staple Edomae topping from a fish that thrived in Tokyo Bay's nutrient-rich waters, its slick skin demanding a sushi chef's careful hand to clean.
- AnmitsuCubes of agar jelly topped with red peas, sweet bean paste, and dark syrup. Said to have begun when a Ginza sweets shop in the early Showa era added its own bean paste to the simpler "mitsumame" — jelly and peas in syrup — marking a point where wagashi met café culture.
- Asakusa shichimiA seven-spice chili blend from a shop tracing back to 1625 in Asakusa's old Yagenbori district, often described as the origin point of shichimi togarashi. The neighborhood's history as a hub for medicinal-herb wholesalers is credited with shaping a blend informed by traditional Chinese medicine, and the shop is known for custom-mixing blends to order.
- Bettara-zukeDaikon salted first, then pickled sweet in rice malt and sugar — said to descend from a lightly pickled daikon once sold at Edo's ebisu-kō market. The rice malt gives it a natural sweetness, and it still headlines Nihonbashi's autumn "Bettara Market."
