About This Project

This site presents a trilingual edition of Tōfu Hyakuchin (豆腐百珍), published in Osaka in Tenmei 2 (1782). It is the world's first known cookbook devoted entirely to a single ingredient — tofu — and it contains one hundred recipes organized into six grades of increasing refinement.

The Author

The book was written under the pen name 醒狂道人何必醇 (Seikyōdōjin Kahitsujun). The prefix Seikyōdōjin (醒狂道人) means roughly "the wayfarer awakened from madness." The real author is believed to be 曽谷学川 (Sodani Gakusen, 1738–1797), an Osaka seal-engraver and amateur — not a professional chef. That a hobbyist produced the most influential single-ingredient cookbook in Japanese history is part of the book's charm.

The name Kahitsujun (何必醇) is often translated as "why must it be rich?" — though the NDL Newsletter offers an alternative reading: that simple dishes can taste just as wonderful as elaborate ones. Both interpretations point to the same conviction: that simplicity, prepared with care and understanding, can be as satisfying as the most lavish feast. This philosophy is visible in the grading system itself: yuyakko (湯やっこ, recipe #97), essentially plain hot tofu served with condiments, is rated Zeppin — Superb — the highest grade. Simplicity, not complexity, is the pinnacle.

The Six Grades

Each recipe is assigned one of six grades, from 尋常品 (Jinjōhin, Commonplace) to 絶品 (Zeppin, Superb). The grades do not strictly correspond to difficulty or complexity — rather, they reflect the author's aesthetic judgment about the dish's ability to reveal the essential nature of tofu.

This Edition

Each recipe opens with an English Interpretation — an interpretive rendering that aims to convey both the cooking instructions and the cultural context of each dish. These renderings are not strictly literal: where the original text is terse or assumes knowledge common to an Edo-period reader, the English version expands and explains. Annotations provide historical, linguistic, and culinary context.

Below the interpretation, two side-by-side panels present the source text:

• Original (1782) — A transcription of the woodblock-printed text in kanji and kana. This layer is being developed through kuzushiji paleographic work and will be added progressively.
• Transliteration — A romanized reading of the original text, also forthcoming.

The Hyakuchin Genre

The success of Tōfu Hyakuchin spawned a publishing phenomenon. Within a few years, similar "one hundred delicacies" books appeared for sweet potatoes, sea bream, eggs, mushrooms, and other ingredients. The hyakuchin genre became one of the most distinctive forms of Edo-period food literature.
