Spollup Co., Ltd. (headquartered in Chofu City, Tokyo; CEO: Shinjiro Yamamoto) has announced the launch of 'Tamagoyaki no Moto'—a specialty egg seasoning from Shōraitei, a renowned ryokan restaurant in Beso Onsen, Ueda City, Nagano Prefecture—on its Rakuten Market store, Kaimono Palette.

This product allows users to create rich, flavorful tamagoyaki simply by mixing it with eggs and cooking. Infused with dashi umami and a gentle sweetness, it brings the refined taste of a traditional restaurant to everyday meals such as breakfast and bento boxes.

Product Features

'Tamagoyaki no Moto' is a seasoning crafted to replicate the signature tamagoyaki of Shōraitei for home use. Based on katsuobushi (bonito) dashi, it incorporates kombu (kelp), dried baby sardines (niboshi), dried shiitake mushrooms, saba (mackerel) katsuobushi, iwashi (sardine) niboshi, and katsuobushi flakes. The mildly sweet, classic flavor profile is enjoyable for all ages, from children to seniors.

Usage is simple: mix with eggs and cook. Ideal for breakfast, bento, or daily side dishes. Beyond tamagoyaki, it can also be used as a hidden flavor enhancer in stir-fries and other dishes.
