“kurogane katapan” is a historic confectionery deeply rooted in the traditions of Kitakyushu. It was originally created during the Taisho era as a nutritional supplement for workers at the state-run Yawata Steel Works. Its most distinctive feature is its iron-like hardness and long shelf life. Made with low moisture content, it has a remarkably long shelf life of approximately 1.5 years. The ingredients include domestically produced wheat flour, sugar, and sweetened condensed milk, with no unnecessary additives, and it is carefully baked using traditional methods. When eaten as is, it offers an exceptionally crunchy texture, while soaking it in coffee, tea, or milk provides a softer consistency. Spina Co., Ltd. has continued to preserve this traditional taste and promote it nationwide as a specialty of Kitakyushu. This confectionery, beloved by the local community, reflects the region’s culture and history. Each piece is carefully baked to achieve its characteristic hardness and rich flavor. Due to its excellent preservation qualities, it is also valued as an emergency food and is ideal for travel or outdoor activities. Spina Co., Ltd. remains committed to honoring regional traditions while developing products that meet contemporary needs.
