Kamakura-don: Prawns Under an Egg Blanket
Two large tempura prawns lay across the rice, with egg and onion draped over their golden coating. The egg made a loose blanket, and not quite a long enough one: both tails stuck out past the rim of the bowl.
This was Kamakura-don at Minemoto’s Komachi-dori branch, near Kamakura Station, south of Tokyo. It follows the same idea as katsudon, a rice bowl topped with a breaded pork cutlet cooked with egg and onion. Here, prawn tempura takes the pork’s place.

Before the prawns
Kamakura-ebi was once a name for the Japanese spiny lobster, better known today as Ise-ebi. In Edo, present-day Tokyo, it was named after Kamakura because that was where it came from. The name appears in Yamato Honzō, a natural-history book published in 1709. That passage explains the lobster’s other name in the same way: Ise-ebi, because so many came from Ise.
That was the seafood used in the earlier Kamakura-don described by two long-established local restaurants, Tenkin and Ishibashi. Chunks of locally caught lobster went into the dish, though the two shops prepared it differently. As catches declined and prices rose in the 1950s and 1960s, lobster became increasingly difficult to serve. Prawns took its place.
At Tenkin, according to its third-generation proprietress, the prawn version began with leftovers: prawn tempura bound with egg and packed into her daughter’s lunchbox. It went down so well that two tempura prawns under egg became the restaurant’s Kamakura-don.
The lobster left the recipe. Kamakura stayed in the name.
Back under the egg
At Minemoto, tofu, pickles and other side dishes were arranged around the red-and-black bowl.

Under the egg, the tempura was excellent: substantial prawns, with egg and onion seasoned to suit them. It was a very good bowl.
Prawns had replaced lobster as the more affordable option.
With two large tempura prawns stretching across the bowl, the cost-cutting was surprisingly hard to spot.
