    Kinugoshi Tofu (絹ごし豆腐)

    Silken Tofu (Kinugoshi Tofu)

    Tofu plays an important role in Japanese traditional cuisine and is loved by most of Japanese. There are so many types of tofu that are on sales in supermarkets in Japan. However, firm tofu (or momen tofu) and silken tofu (or kinugoshi tofu) are among the most common tofu in Japan. Today, let’s find out what is kinugoshi tofu and how Japanese people turn it into such amazing dishes!

    What is Kinugoshi Tofu?

    Kinugoshi Tofu (絹ごし豆腐) is silken tofu with soft and smooth texture. In contrast to momen tofu (firm tofu), kinugoshi tofu has a smooth texture like silk so it is named kinugoshi (in Japanese, kinu 絹 literally means silk). Because of its name, some people often misunderstand that this tofu is made from silk; however, this is not true.

    While momen tofu is used in boil and stir-fry dishes, silken tofu is mostly eaten straight and used as ingredient for salad, hiyayakko, etc.


    Silken Tofu

    The origin of Tofu

    Tofu is a processed soybean food that has been eaten in wide areas of East and South-East Asia since ancient time. There are various theories about the origin of it.

    One theory bases on a record in the 16thth-century Chinese book called “Honzo Koumoku” saying that “Tofu was first invented by Liu An, who was a Han dynasty Chinese prince and ruled the Huainan Kingdom. However, this theory is not believed by many people because there is no historical record of tofu until the Tang Dynasty.

    The most strong theory on the origin of tofu holds that it originated in the Tang Dynasty between the 8th and 9th century. The word “tofu” is believed to first appear in the book called “Shinroku” in 10th century.

    Introduction to Japan

    The Japanese missions to the Tang China during the Nara period (710-784) impacted Japanese lifestyle a lot, including its food culture. After those missions, Japanese envoys returned to Japan and brought back “tofu”. However, during this time, tofu was considered as vegetarian food for monks, and then spread to samurai and aristocrats.

    It was not until the Edo period that tofu began to become popular among the common people. During that time, the type of tofu that was eaten was momen tofu. Then, how about the silken tofu? Let’s find out in the next section!

    First appearance of silken tofu

    Kinugoshi tofu (or silken tofu) first appeared in the middle of the Edo period. In 1691, Tamaya Chubei invented silken tofu. In the 4th year of the Genroku era (about 315 years ago), he, accompanied by Ueno prince (Imperial Prince of the 111th Emperor Gosai), moved from Kyoto to Edo (former name of Tokyo) and opened a teahouse.

    Imperial prince Ueno really liked the silken tofu and praised it as “beautiful as snow on bamboo”. He also named it “Sasanoyuki” (笹乃雪) (literally “snow on bamboo”). There is also a long-established shop called “Sasanoyuki” that is still popular in Japan up until now.

    In Hakuho no Sato, Yonago City, Tottori Prefecture, there is an event called “Usotsuki Tofu Day” (literally Liar Tofu Day) held annually on the Saturday closest to December 8th.
