The gravesite of the Aizu Matsudaira clan of the Aizu domain, which was designated as a national historic site in 1987, is situated on Mount Innai, to the east of the entrance to Higashiyama Onsen hot spring. Local people call it the “Innai Mausoleum.”
The entrance at the foot of the mountain is somewhat awesome, rather like a checkpoint. There is a place for washing your hands as an act of purification, giving visitors the feeling that they are about to enter a sacred place. As you climb up the densely wooded mountain path, you begin to feel a certain power in the air.
After walking for about 15 minutes, just as you are beginning to get out of breath, you come to a long and narrow open space with large stone monuments ahead of you. These monuments are built on top of large stone tortoises and are inscribed with epitaphs of Aizu clan daimyo, giving their names, achievements, histories, and other information.
The large tortoise is an imaginary animal of Chinese legend called the black tortoise that protects the spirits of the dead. In Japanese it is known as genbu. Since the black tortoise is a deity defending the northern direction, its face is always facing north. The first Aizu Matsudaira clan lord, Hoshina Masayuki (1611-72), is not buried here but at Hanitsu Shrine in Inawashiro, which lies to the north.
The genbu has piercing eyes, sharp fangs, and claws, and pointed ears. Viewed from the side, it looks ready to pounce at anytime. But seen from above, it looks as though it is prostrating itself before the lord asleep in the grave and worshipping him.
Behind and above the monument of each grave there are two stone lanterns, and behind and above them there is the omoteishi, a kind of stone marker bearing the rank, status, and so forth of the lord. Beyond the omoteishi, on top of a round burial mound, there is an octagonal shizumeishi gravestone for the repose of the daimyo’s soul.
Although the grave of the second daimyo is Buddhist style, those of the third to ninth daimyo are Shinto style. Other family members and descendants are also buried here.
Visitors to the gravesite were heard to say that they felt soothed or empowered by the experience. Borrowing a phrase that has become popular recently, perhaps we can truly describe this place as a tourist “power spot.”
