What is it?
Kamome no Tamago is Saito Seika's egg-shaped confection from Ofunato on Iwate's Sanriku coast. A yellow bean-paste center is wrapped in a thin cake layer and coated in white chocolate, giving the cut sweet three distinct colors and textures.
The name means seagull's egg and the smooth white form evokes birds along the Sanriku shore. It is a branded product, so the maker and official product name are more precise than treating it as a general homemade sweet.
History and local context
Saito Seika's company history places the product's birth in 1952. It grew from a regional confection into a widely recognized Iwate souvenir while the business remained closely tied to Ofunato and post-disaster reconstruction on the coast.
Seasonal coatings and sizes appear in addition to the standard version. The basic reference point remains the white egg shape, yellow bean paste and cake layer shown by the maker.
How to enjoy it
Cut one in half to see the layers, then let it approach room temperature for a softer bean-paste aroma. Tea and lightly bitter coffee both balance the white-chocolate sweetness.
For gifts, compare standard and mini sizes, piece count, individual wrapping, season-limited flavors and the printed best-before date. Use the official shop or authorized retailers when confirming current assortments.
This is a branded commercial confection; compare the maker and authorized seller when purchasing.
