OGA Brewing Company

OGA Brewing Company is a brewery based in Japan. It is associated with the Drunk bat beer brand, which is sold through the Drunk bat Online Shop, an age-restricted e-commerce site operated on the FC2 cart platform. The shop requires visitors to confirm they are at least 20 years old before entering, in line with Japanese regulations on the sale of alcoholic beverages. Beyond its Japanese origin and its connection to the Drunk bat online storefront, little verified public information is available about the company's founding, ownership, brewing facilities, or product range. The brewery appears to operate as a small craft producer, and its online shop serves as the primary direct-to-consumer sales channel.
