Sekibutsu, literally "stone Buddhas" are usually statues, but these are reliefs carved into stone surfaces, and such are technically magaibutsu.
Sometimes magaibutsu are carved into large boulders, the biggest examples being carved into cliffs, but a common form is carved into the walls of small "caves" formed by overhanging rock.
They are not very common in Japan, but Oita in northern Kyushu is home to the vast majority in Japan.
These near Karatsu in Saga were a big surprise, though not too far away is a modern cliff carving I visited a few days before, the
Taikoiwa Fudoson.
The ones here at Udono were said to have been first carved in the 9th century, though these seem to no longer exist. Some were carved as recently as the Edo Period, but the most impressive ones date from the 14th century and include a Kannon, a Fudo Myo, a Bishamonten, and a Jikokuten. In total, there are almost 60.
I discovered these cool carvings quite by accident. I stopped in at the small tourist information office in the station at Ochi and they told me about them. They lent me a free rental bike and let me leave my pack with them while I went to explore them.
As mentioned earlier, Oita is home to the most magaibutsu in Japan, with the Kunisaki area having the biggest, the
Kumano Magaibutsu, however the most impressive are down near Usuki and are known as the
Usuki Stone buddhas.
