羊羹
ようかん
yokan
= a firm, jellied Japanese confection made from red bean paste, agar, and sugar
Yokan is one of Japan’s oldest surviving confections — a dense, glossy block of sweetened red bean paste set with agar that has been refined over centuries from a Chinese soup into a jewel-like wagashi (traditional Japanese sweet). Its subtle sweetness and smooth texture make it the canonical accompaniment to a bowl of matcha.
Yokan (羊羹) is a firm wagashi (traditional Japanese confection) made primarily from anko (red bean paste), kanten (agar-agar), and sugar, molded into rectangular blocks and sliced into pieces before serving. Two main varieties exist: neri yokan (練り羊羹), which is firmer and has a longer shelf life due to its lower moisture content, and mizu yokan (水羊羹), which contains more water and has a lighter, softer texture suited to summer. Premium yokan may incorporate flavors such as matcha, chestnut (kuri), sesame, or citrus. The word itself is written with the characters for ‘sheep’ (羊) and ‘soup’ (羹), reflecting its historical origin as a mutton broth dish introduced from Tang dynasty China.
Yokan is traditionally eaten with Japanese green tea, particularly matcha or gyokuro, as its sweetness balances the tea’s bitterness. When buying yokan as a souvenir (omiyage), look for regionally distinctive varieties — Toraya in Tokyo is Japan’s most famous yokan producer, but nearly every prefecture has its own specialty. Mizu yokan is best served chilled in summer; neri yokan can be stored at room temperature for weeks or even months. Slicing is done with a fine wire or sharp knife to preserve the glossy surface.
The kanji 羊羹 literally means ‘sheep soup’ — 羊 (yō) means ‘sheep’ and 羹 (kan) means ‘thick soup’ or ‘broth.’ The name reflects the dish’s original form as a meat-based broth brought from China during the Kamakura period. When Buddhist monks adapted it to a vegetarian form using beans and agar, the name was retained even as the dish transformed entirely into the confection known today.

Yokan’s journey from Chinese mutton broth to Japanese confection is one of the most dramatic culinary transformations in Japanese food history. When Zen Buddhist monks brought the recipe from Song dynasty China during the Kamakura period (12th–14th centuries), religious dietary restrictions prevented the use of meat, so they substituted azuki beans. Over the following centuries — particularly during the Edo period when refined sugar became more accessible — yokan evolved into the polished, aesthetically precise confection it is today. The Toraya confectionery, which has been making yokan since the late Muromachi period and served the imperial court, remains the gold standard.
In contemporary Japan, yokan occupies a unique cultural position as both an everyday treat and a high-end gift. Its shelf stability — premium neri yokan can last months without refrigeration — made it historically important as a preserved food, and it was included in military rations during the Meiji and Taisho eras. Today, seasonal and regional yokan varieties reflect Japan’s gift-giving culture: spring brings sakura yokan with cherry blossom petals suspended in the jelly, autumn brings chestnut varieties, and local shops across Japan produce prefecture-specific flavors using local ingredients like yuzu from Kochi or Kyoto’s matcha.
