Goma-dofu, or sesame tofu, is one of the most distinctive traditional dishes of Koyasan, a sacred Buddhist mountain center in Wakayama Prefecture. Although its name literally means “sesame tofu,” it is completely different from ordinary tofu made from soybeans.
Instead, the main ingredients are sesame seeds and kudzu starch. Traditional recipes use high-quality hon-kudzu or Yoshino kudzu, producing a smooth, delicate texture with a gentle firmness. The rich aroma of sesame combined with the silky texture of kudzu makes goma-dofu a memorable part of the Koyasan culinary experience.
Goma-dofu is more than simply a local specialty. Its history is closely connected with the approximately 1,200-year history of Koyasan, Buddhist practice, and shojin ryori, the vegetarian cuisine traditionally prepared in Buddhist temples. The dish represents a food culture that developed alongside the religious life of Koyasan and continues to be enjoyed by visitors today.
Goma-dofu is traditionally said to have developed at Koyasan as part of the food prepared for Buddhist monks. Koyasan was founded by Kobo Daishi, also known as Kukai, and vegetarian temple cuisine has been an important part of life in the mountain sanctuary for centuries.
Shojin ryori follows Buddhist principles and generally avoids meat and fish. Instead, meals are prepared using ingredients such as vegetables, beans, wild mountain plants, mushrooms, and seaweed.
In a diet without animal products, nutritious plant-based ingredients were especially important. Sesame seeds were valued as a rich source of nutrients, including protein and fats, and have long been regarded as an important food in East Asian culinary traditions.
One tradition holds that Kobo Daishi brought sesame back to Japan after traveling to China as part of a Japanese diplomatic mission and began cultivating it at Koyasan. While this story is part of the traditional lore surrounding the dish, it illustrates the close relationship between Koyasan, Buddhist culture, and sesame.
Goma-dofu is thought to have been developed as a way of making effective use of the nutritional value of sesame during the demanding life of Buddhist practice. Another theory traces its origins to a dish called “madofu” described in the Wakan Shojin Ryori Sho, a cookbook published in 1697.
The distinctive character of Koyasan goma-dofu comes from both its ingredients and its careful preparation. The principal ingredients are white sesame seeds and kudzu starch, traditionally including high-quality hon-kudzu or Yoshino kudzu.
The sesame seeds are carefully prepared and ground until they become an extremely fine paste. This process takes considerable time and effort, but it is essential for producing the characteristic smooth texture of good goma-dofu.
The ground sesame is then combined with kudzu starch dissolved in water. The mixture is heated and stirred and kneaded continuously until the sesame and kudzu become a unified, thick mixture. It is then poured into molds and allowed to cool and set.
One of the greatest pleasures of high-quality Koyasan goma-dofu is its silky, almost velvety texture. Carefully grinding the sesame and repeatedly straining it removes coarse particles and produces an exceptionally fine consistency.
Some traditional preparation methods involve straining the mixture as many as three times to achieve an even smoother finish. When rare hon-kudzu is added and the mixture is carefully kneaded, the result is a beautiful white goma-dofu with a smooth texture and just the right amount of firmness.
The extensive preparation reflects more than a pursuit of culinary perfection. In Zen Buddhist temples, cooking itself has traditionally been regarded as a form of practice. Carefully handling ingredients and devoting attention to every stage of preparation reflects the spirit of shojin ryori.
For centuries, goma-dofu has been an important part of the vegetarian meals prepared for Buddhist monks at Koyasan. Without meat or fish, sesame provided a valuable source of plant-based nutrition and helped support the demanding lifestyle of religious practice.
Today, goma-dofu remains a classic part of shojin ryori served at Buddhist temples and temple lodgings, particularly at Koyasan and in neighboring regions such as Wakayama, Nara, and Kyoto.
Japanese temple cuisine should not be thought of simply as plain food without meat or fish. Traditional cooks use seasonal vegetables, mountain plants, beans, mushrooms, and seaweed and employ a wide variety of techniques to bring out their natural flavors.
Within these carefully prepared meals, goma-dofu has a special place. Its elegant appearance, rich sesame flavor, and delicate texture make it one of the signature dishes of Koyasan’s culinary culture.
Koyasan is a major center of Japanese Buddhism located high in the mountains, surrounded by peaks reaching around 1,000 meters in elevation. Over its long history, a distinctive religious and cultural tradition developed here, including its own approach to food.
Shojin ryori emphasizes vegetables, beans, mountain plants, mushrooms, and seaweed. Although animal products are avoided, cooks have developed numerous techniques for bringing out the best in each ingredient.
Koyasan has also welcomed pilgrims and visitors from across Japan for centuries. The tradition of serving meals to pilgrims gradually became an important part of the culture of the mountain sanctuary, and this tradition continues today in the shukubo, or temple lodgings.
The meals served to visitors are often more elaborate than the simple everyday meals eaten by monks. Seasonal ingredients, beautiful presentation, and a spirit of hospitality are carefully incorporated into the dining experience.
Goma-dofu is one of the dishes that beautifully represents this combination of Buddhist tradition, seasonal food culture, and Japanese hospitality.
Koyasan shojin ryori is traditionally associated with the principles of five flavors, five colors, and five cooking methods. These concepts emphasize balance and harmony in taste, appearance, and preparation.
The five flavors traditionally refer to sweet, sour, spicy, bitter, and salty. Shojin ryori seeks to create balance among these flavors while allowing the natural character of vegetables, beans, seaweed, and other ingredients to remain noticeable.
Goma-dofu can be served with different seasonings, each creating a different taste. Wasabi and soy sauce provide a combination of savory flavor and refreshing heat, while vinegared miso offers a pleasantly sweet and sour contrast to the rich sesame flavor.
The principle of five colors traditionally emphasizes white, yellow, red, green, and black. Natural colors from ingredients are used to create an attractive and balanced meal.
White tofu or daikon radish, yellow pumpkin, red carrots, green vegetables, and black mushrooms or seaweed can all contribute to the visual harmony of the meal.
With its pure white color and smooth surface, goma-dofu is particularly beautiful when placed among colorful seasonal dishes. Shojin ryori demonstrates the Japanese idea that food should be appreciated not only through taste but also through sight.
The five traditional cooking methods include raw preparation, simmering, grilling, frying, and steaming. By changing the cooking method, the same ingredient can produce completely different textures, aromas, and flavors.
The restrictions of shojin ryori encouraged cooks to develop creative ways of preparing plant-based ingredients. Goma-dofu itself demonstrates this attention to technique: the sesame is ground and strained, combined with kudzu, carefully kneaded, and then cooled until it reaches its distinctive consistency.
One of the pleasures of goma-dofu is the variety of ways it can be served. A classic accompaniment is wasabi and soy sauce. The savory taste of soy sauce and the refreshing sharpness of wasabi complement the rich, mellow flavor of sesame.
Another popular option is vinegared miso. Its gentle sweetness and acidity provide a refreshing contrast and bring out the depth of the sesame flavor.
Goma-dofu may also be served with a delicate Japanese broth or dashi-based seasoning, allowing its subtle flavor and texture to take center stage. In temple cuisine, it can be presented alongside seasonal dishes as part of a carefully balanced meal.
Goma-dofu can even be enjoyed as a dessert. Some preparations are served with Wasanbon sugar or kuromitsu brown sugar syrup, creating a refined Japanese sweet with a smooth and gentle texture.
The combination of sesame, kudzu, and sweet syrup produces a flavor that is quite different from savory goma-dofu, demonstrating the versatility of this traditional dish.
Another variety is nama goma-dofu, made using unroasted sesame seeds. Compared with goma-dofu made from roasted sesame, it offers a more delicate and fresh sesame flavor.
Some tofu shops and specialty producers in Wakayama sell nama goma-dofu by order or in limited quantities. Because it has a relatively short shelf life, it should generally be enjoyed soon after purchase.
The short shelf life is part of its appeal: visitors can experience a particularly fresh expression of goma-dofu, close to the flavor and texture of the freshly prepared dish.
Goma-dofu became widely recognized as one of Koyasan’s signature souvenirs during the Showa period. Today, it can be found at souvenir shops and specialty stores around Koyasan, as well as in nearby regions such as Yoshino.
Modern commercial production has also made goma-dofu available outside the temple district, including at supermarkets and other food retailers. A dish with centuries of religious history has thus become something that can also be enjoyed in everyday life.
Different producers create goma-dofu with slightly different levels of sesame flavor, softness, and firmness. Trying several varieties can be an enjoyable way to discover the subtle differences between recipes.
Koyasan goma-dofu is a traditional food that embodies the history of Buddhist practice and culinary culture developed over approximately 1,200 years. Its ingredients may be simple—sesame and kudzu—but its preparation requires considerable time, skill, and patience.
Originally associated with the vegetarian cuisine that supported Buddhist monks, goma-dofu has evolved into one of the foods most strongly associated with Koyasan. Today, visitors can enjoy it as part of a traditional temple meal, purchase it as a souvenir, or experience different preparations with savory or sweet seasonings.
When visiting Koyasan, take time not only to explore its temples and sacred sites but also to experience its shojin ryori. Sitting down to a carefully prepared meal and tasting silky goma-dofu offers a unique way to connect with the history and culture of this sacred mountain.
With its emphasis on natural ingredients, careful preparation, balance, and mindfulness, goma-dofu represents the spirit of Koyasan’s food culture. It is a simple yet refined traditional dish that allows visitors to experience a small but meaningful part of Japan’s Buddhist culinary heritage.
