What is it?
Tsuki de Hirotta Tamago is Asahi Seika's round, pale-yellow steamed sponge cake. The standard cake contains custard made with Yamaguchi milk and pieces of domestic Japanese chestnut, combining airy cake, soft cream and a small nutty bite.
Launched in 1986 and initially adopted as an All Nippon Airways in-flight sweet, it is a specific modern product rather than a generic historical confection. In Yamaguchi it is also nicknamed Tsukitama.
History and local context
The maker highlights fresh domestic eggs, Yamaguchi milk, Japanese chestnuts and a two-stage steaming method using Kinmeisui water. Seasonal variants have different fillings and should not inherit every standard-product claim.
The official history says the softer-sounding name won over another candidate, Moon Egg. Showing its custard-and-chestnut cross-section also distinguishes it from similar custard cakes elsewhere in Japan.
How to enjoy it
Cut one at room temperature to see the crumb, custard and chopped chestnut together. Light chilling firms the cream, but follow the package's storage directions.
The standard product contains egg, milk, wheat and chestnut. Check the current label, date and cross-contact notice.
This is a branded commercial confection; compare the maker and authorized seller when purchasing.
