Landscape of the abyss was made by lave of eruption of Mt. Natai. There are giant rocks on the riverside. In addition to that, stone image of Fudo Myouou was put on the rock. The stone image of Fudo Myouou was made by Bishop Koukai. The name of "Kanman" is the last phrase of Shingon incantation. This abyss also pronounced Ganman, but Kanman is the correct pronunciation judging from the origin of the naming.

You will go out to a parking lot after you crossed the Kanman Bridge. You will find the bridge if you walk along with the river of Daiya from Shinkyo Bridge. There will be the park called "Stone Park" after you passed the parking lot. You will arrive at Jiunji Temple and Bake Jizou (as known as 100-jizou) if you go forward the central road of the Stone Park. The area of the Bake Jizou and Jiunji Temple is located in a small valley of the river of Daiya. That area is called Kanmangafuchi Abyss.

There is a monument of poem, which was given by the Emperor of Taisho period. That poem was made when he was strolling around the kanmangafuchi Abyss. Meaning of his poem was as follows:
"Sleeves were wet by the spray at the river of Daiya. Cold moonlight night comes over the shore."

Priest Koukai built the Jiunji Temple in 1654, but the original building was washed away by the flooding in 1902. It was rebuilt in 1973.

You will find Reihi-kaku on the right hand if you go to the upstream. Priest Koukai built the Reihi-kaku when he built the Jiunji Temple. A holy fire was burned at the Reihi-kaku. That fire faced the stone image of Fudo Myouou, which was located on the opposite shore. However, the Reihi-kaku also was washed away, and today's building was reformed in 1971.

There is a Sanskrit inscription on the cliff of opposite shore of Reihi-kaku. That Sanskrit means Kanman. According to a legend, Saint Kukai Kobo threw the brush and carved that inscription. That legend is called "Thrown brush of Kobo." However, truth is that Priest Sanjun wrote the Sanskrit and Priest Koukai made to carve it. That legend was told incorrectly because Koukai and Kukai (Saint Kobo) have similar pronunciation.

There is a group of about 70 Jizous after the Reihi-kaku. Those Jizous are put in a line. Each of these Jizou was carved by follower of Bishop Tenkai, but there were about 100 Jizous at that time. However, some of those were washed away by flooding in 1902. Oya-jizou (Parent Jizou) was put on the head of the group of Jizo, but was also washed away. However, a local person found a head of the Oya-jizou at the bottom of the river, and the head has been enshrined in Joukouji Temple today.

The group of Jizo is called "Bake-jizou," "Narabi-jizou (Jizous in a line)," or "Hyaku-jizou (100-Jizou)." The name of the Bake-jizou derives from two stories. Number of Jizous did not match to the certain number even though these were counted many times. It was like a ghost. The ghost is "Bake" in Japanese. Another story is that Bakku-yoraku of Buddhist term was shortened to "Bake."

There is Nikko Botanical Garden across the river of Daiya. You can enjoy being there throughout the year. For example, green leaves in the spring, autumnal leaves, and Jizou will be covered with snow in the winter.
