Ogi Yokan is a famous yokan (sweet bean jelly) product developed in Ogi City, Saga Prefecture, from the Meiji era onward. During the Edo period, the Nagasaki Kaidō, which connected Nagasaki and Kokura, was also known as the 'Sugar Road' because sugar brought by Nanban (European) trade was transported along it, and Ogi, one of the sugar collection points along the route, likewise developed a flourishing confectionery culture. In 1899, the founder of Muraoka Sohonpo learned yokan-making techniques from a yokan artisan in Nagasaki and began producing yokan there, and it is said that the second-generation head, Muraoka Yasukichi, was the first to use the name 'Ogi Yokan.' Ogi is a rare production area nationally, with more than twenty yokan shops clustered in a small town of about 50,000 people, and in 2020 it was certified as a component asset of the Japan Heritage designation 'The Nagasaki Kaidō That Spread Sugar Culture — the Sugar Road.' The fact that Ogi flourished as a castle town of the Nabeshima Domain is also said to have provided fertile ground for its confectionery culture to blossom.
Origin
The Nagasaki Kaidō, which carried sugar from Nagasaki — a gateway for Nanban trade — to Kokura, is also known as the 'Sugar Road,' and a confectionery culture using sugar took root in towns along the route. Ogi, one of the sugar collection points, likewise developed a thriving confectionery industry, and it is said that the origin of Ogi Yokan traces back to 1899, when the founder of Muraoka Sohonpo learned yokan-making techniques from a yokan artisan in Nagasaki and began making yokan.
History
It is said that, not long after the shop's founding, the second-generation head Muraoka Yasukichi wrote the name 'Ogi Yokan' on the wooden boxes used to transport the yokan, marking the origin of the name. In the early Showa era, it is said to have been prized by the military for its long shelf life, and yokan shops subsequently opened one after another in Ogi. Today, more than twenty yokan shops line the streets of Ogi City, a town of about 50,000 people, and in 2020 it was certified as a Japan Heritage component asset of the Nagasaki Kaidō Sugar Road.
Features
Its defining feature is the 'kiri-yōkan' (sliced yokan) method, in which a paste of kneaded azuki beans, sugar, and agar is poured into wooden boxes and left to air-dry naturally for a full day and night as it sets. As moisture evaporates from the surface, sugar crystals form, giving the outside a crisp, crunchy texture while the inside remains moist — allowing a single piece of yokan to offer two contrasting textures.
Main Ingredients
Food Culture
Against the backdrop of a sugar culture rooted in Nanban trade that took hold along the Nagasaki Kaidō, yokan-making developed into a local industry in Ogi. The number of yokan shops is remarkably high relative to the town's population, and Ogi Yokan has become a representative local specialty, cherished both within and beyond Saga Prefecture as a gift item and souvenir.
How It Differs from Home Cooking
Homemade neri-yokan is typically poured into a mold and finished ready to eat right away, whereas Ogi Yokan differs in that it is left in wooden boxes to air-dry naturally for a day and night or more, a process that forms sugar crystals on the surface.

Q. Why is the surface of Ogi Yokan crisp and crunchy?
A. It is due to the 'kiri-yōkan' method, in which the kneaded paste is placed in wooden boxes and left to air-dry naturally for a full day and night, causing moisture on the surface to evaporate and sugar crystals to form. The inside remains moist.
