"Oyatsu" refers to a light snack or sweet enjoyed in Japan between lunch and dinner. These snacks come in a variety of flavors, from sweet to savory, and are widely enjoyed as a refreshing break. This culture is embraced by both children and adults, with traditional dagashi (old-fashioned sweets) and region-specific treats being particularly popular.

Currently, "Oyatsu Club" is developing a subscription box service. The goal is to deliver a carefully curated selection of Japan's unique and seasonal snacks, along with beverages such as tea that pair perfectly with them, to people living overseas. Each month, these snacks will be delivered as part of a snack box, offering an authentic taste of Japan.
