Nihon Hokke Genki, Upper Volume: A 1153 Manuscript on Mount Kōya
A short note brushed at the end of this book tells us when it was made. A scribe completed the copy in the middle of summer in 1153, the third year of the Ninpei era. What he copied was the opening volume of the Nihon Hokke Genki, a collection of Buddhist tales first assembled on Mount Hiei roughly a century before. The original is long gone. Surviving copies like this one, kept by the temple of Hōju-in on Mount Kōya, are how the text reached us at all.
The book is a single bound volume, classed by the government as shoseki tenseki, the category for calligraphy and old manuscripts. It carries no illustrations and makes no display of itself. Its value lies in the words and in its age: a hand-copied text standing close in time to a work that shaped how medieval Japan told stories about faith.
What the Nihon Hokke Genki Is
The full title is Dai Nihonkoku Hokke Genki, usually shortened to Hokke Genki. Genki means a record of miraculous responses. A monk named Chingen compiled it during the Chōkyū era, between 1040 and 1044. Chingen belonged to Shuryōgon-in, a hall in the Yokawa precinct of Enryaku-ji, the great Tendai temple complex on Mount Hiei near Kyoto. His own biography is largely unknown, though he is thought to have moved in the circle around Genshin, the monk whose Ōjō Yōshū gave Pure Land devotion in Japan much of its early shape.
In his preface, Chingen names his model: a Chinese-tradition Hokke Genki attributed to the monk Yishaku, a work that no longer survives. He set out to make a Japanese counterpart, gathering accounts of people whose devotion to the Lotus Sutra brought some visible sign or reward.
The Lotus Sutra, Hokekyō in Japanese, was among the most revered scriptures in Heian Buddhism. Reciting it, copying it, or simply holding to it was believed to erase past wrongdoing and open the way to a better rebirth. The men and women in these tales are jikyōsha, holders of the sutra, and the book is in large part a gallery of their lives.
Why It Was Designated
The Agency for Cultural Affairs registered this volume as an Important Cultural Property on 19 February 1957. Two things explain the listing. The first is the text itself. Because Chingen's original is lost, early manuscripts carry the burden of preserving the work, and a copy with a firm date of 1153 sits only about a hundred years downstream from the compilation. That closeness matters to scholars trying to recover what Chingen actually wrote.
The second is the place it has been kept. Hōju-in is a sub-temple of the monastic town on Mount Kōya, the center of Shingon Buddhism founded by Kūkai in the early ninth century. A Tendai miracle anthology preserved in a Shingon stronghold is a reminder that books traveled across sectarian lines, copied and treasured wherever readers valued them.
What Makes the Text Worth Knowing
A cast that runs from saints to snakes
The complete Hokke Genki fills three volumes and holds 129 short biographies. They are arranged by rank of being. Bodhisattvas come first, represented by figures such as Prince Shōtoku and the monk Gyōki. Then come ordained monks, including Saichō and Ennin, the founders and builders of the Tendai school. After them follow lay novices, nuns, laymen, and laywomen. The final group is the most unusual: irui, beings that are not human. Snakes, monkeys, and other creatures appear here as recipients of the sutra's power. Earlier collections of rebirth tales had stopped at people. Chingen's decision to extend the reward to animals gives the book a distinctive reach.
A source mine for later storytellers
Chingen did not invent everything. He drew on the Nihon Ōjō Gokurakuki, the Sanbōe, monastic biographies of Saichō and Ennin, and tales that echo the older Nihon Ryōiki. Some lives, though, seem to come from his own knowledge and hearsay, including those of the ascetics Shōkū and Sōō. The flow ran forward as well. The compilers of the Konjaku Monogatarishū, the vast late-Heian tale collection, took many of their Lotus Sutra miracle stories straight from this book. Reading the Hokke Genki means reading a hinge between earlier Buddhist biography and the storytelling that followed.
A theme of escape
Underneath the tales runs the idea of rebirth and the wish to be free of it. Recitation of the Lotus Sutra is offered again and again as the means of wiping out old sins, and many of the figures are mountain ascetics who pursued that practice in forest and cave. The book leans toward this hard, solitary discipline rather than the later image of wandering preachers spreading faith among ordinary people.
Seeing It, and the Mountain Around It
The manuscript is held at the Kōyasan Reihōkan, the museum that safeguards the cultural property of Mount Kōya on behalf of the temples. Old paper documents are fragile and light-sensitive, so this volume is not on permanent view. It appears only when a special or seasonal exhibition calls for it, such as a show devoted to the treasures of Hōju-in or to early calligraphy and manuscripts. Anyone hoping to see the book itself should check the museum's current exhibition schedule before traveling.
The Reihōkan is worth a visit regardless. Its galleries rotate through the National Treasures and Important Cultural Properties of the mountain, among them the oldest dated Nehan-zu painting of the Buddha's passing, from 1086. Photography and sketching are not permitted inside, and there is no café on site.
Mount Kōya rewards a longer stay. The Danjō Garan, the central temple compound laid out by Kūkai, and Kongōbuji, the head temple of Shingon, sit within easy walking distance. Okunoin, the forested cemetery leading to Kūkai's mausoleum, stretches for two kilometers beneath towering cedars and is at its most atmospheric in early morning or at dusk. Many of the mountain's temples offer lodging, shukubō, where guests share vegetarian temple meals and may join morning prayers.

Q&A
- Can I see this manuscript when I visit Mount Kōya?
- Not at any time. As a fragile paper manuscript, it is kept in storage at the Kōyasan Reihōkan and shown only during specific exhibitions. Check the museum's exhibition listings before your trip if seeing the book is your goal.
- Is this the original work?
- No. Chingen compiled the text in the 1040s, and his original does not survive. This is a copy made in 1153, which is one reason it is valued: it preserves the text from a point close to its creation.
- Why is a Tendai text kept at a Shingon temple?
- Books crossed sectarian boundaries freely. Chingen worked in the Tendai school on Mount Hiei, but his anthology was copied and preserved at Hōju-in on Mount Kōya, the Shingon center, where it has remained.
- What is a "jō," the unit used to count it?
- The designation lists the work as one jō, a counter for a bound booklet rather than a rolled scroll. The surviving designated item is the upper, or first, of the work's three volumes.
- How do I reach the Kōyasan Reihōkan?
- Take the Nankai line from Namba in Osaka to Gokurakubashi, then the cable car up to Kōyasan. From the station, a Nankai Rinkan bus runs to the "Reihōkan-mae" stop. Driving is also possible, with free parking at the museum.
