1. The History and Production of Kokuto

• Origins: Introduced from China in the 17th century during the Ryukyu Kingdom era, Kokuto has been a staple for over 400 years.
• Production Method: The process remains simple and traditional: sugarcane is harvested, pressed for juice, and boiled in large cauldrons. A small amount of lime powder is added to facilitate solidification.
• Regional Specialization: While produced on the main island, the highest concentration of production occurs on eight smaller islands, such as Ie-jima, which features soil formed by uplifted coral reefs.
• Artisanal Craft: Artisans like Toguchi Suguru emphasize the importance of wood-fire boiling and constant stirring during the cooling process to achieve the correct texture and aroma, often described as "roasted marshmallows."

2. Cultural and Nutritional Significance

• Resilience: Sugarcane is viewed as a symbol of Okinawan resilience, noted for its ability to recover quickly after being knocked down, a trait that provided psychological comfort to islanders during the devastation of World War II.
• Nutritional Value: Historically, Kokuto served as an "energy drink" for laborers. It is rich in vitamins and minerals that help replenish electrolytes lost through sweat in the subtropical climate.
• Culinary Application: Beyond a sweetener, it is used in savory dishes (e.g., wild boar seasoned with Kokuto, salt, and sake) to provide depth, umami, and mineral complexity that refined white sugar lacks.

3. Modern Innovation and Economic Support

• The Rum Initiative: To combat declining demand and surplus inventory caused by the COVID-19 pandemic, distiller Nakazato Akida began producing rum using different varieties of Kokuto. This adds value to the raw ingredient and creates a new market for Okinawan products.
• Upcycling Framework: Bartender Sugioda Satoshi utilizes a "circular" approach to mixology. He incorporates agricultural waste—such as assa (sea lettuce) that has discolored or shiquasa limes discarded after juicing—into his spiced rums.
• Economic Impact: This methodology connects the hospitality industry directly to local farmers and distillers, ensuring that even "imperfect" produce is utilized, thereby supporting the local economy and reducing waste.

4. Key Perspectives and Quotes

• Michael Kea (Host): "Cotto has always reminded me of the southern Japanese islands... the connection between sugarcane and Okinawa goes deeper than the soil in which it is grown."
• Sugioda Satoshi (Bartender): Regarding his collaboration with local producers: "We have a strong connection to the world, so we just want to support them by introducing how Okinawa has a great product here."
• Crystal Bernett (Health/Culture Researcher): Highlights that Kokuto is not just a sugar but a functional food, comparing it to modern energy drinks for its ability to replenish nutrients.

5. Synthesis and Conclusion

The journey of Kokuto in Okinawa represents a transition from a historical survival staple to a modern symbol of cultural identity and economic innovation. By maintaining traditional, labor-intensive production methods, Okinawan artisans preserve a unique flavor profile. Simultaneously, the integration of Kokuto into the craft spirits industry—specifically through the upcycling of local agricultural byproducts—demonstrates a sustainable model for preserving heritage. The enduring spirit of Yuimaru (mutual support) remains the driving force, ensuring that the island's food culture continues to evolve while honoring its 400-year-old roots.
