Thank you for viewing. This is a traditional hand-held roasting pan used in Showa-era kitchens for roasting ginkgo nuts, arare rice crackers, beans, and other items. Many people likely remember the sound and aroma of roasting ginkgo nuts. The mesh ensures even heat distribution, resulting in a fragrant and delicious finish. Its simple construction makes it durable, and it can still be used perfectly today. It's also recommended for outdoor cooking, shichirin grilling, and as a display item in a traditional-style cafe. This type is no longer manufactured, making it a valuable item both for practical use and as a collectible. I would be very encouraged if you have any questions.
