Holy Mary-Kannon of Harajo Castle, in Minami-Shimabara
The world’s tallest wooden Holy Mary-Kannon statue, with 10 meters in height.
The statue is located in Minami-Shimabara-city, 10 minutes drive from Hara Castle Ruins,
where is the site of the Battle field of Shimabara Rebellion.
The statue was created by Sculptor Oyamatsu Eiji.
Realizing in the youth that there were no commemorative monuments in Hara Castle, he decided
to create a statue of Holy Mary after the visit of the Pope to Japan in 1981. In order to give peace
to souls of the victims of Shimabara Rebellion, he kept creating for 40 years on his own the statue
as his personal masterpiece of lifetime. He hopes that the statue can provide relief to the soul and
a place for healing, and christened the statue “Holy Mary-Kannon of Hara Castle” as a hope for
peace, regardless of any religious belief.

Hinoe Castle Ruins
During the period of the Southern and Northern Courts (1337-92), the Arima family ruling
the Shimabara Peninsula constructed a castle named Hinoe-jo. The 14th lord, Harunobu
(1567-1612) was a Christian daimyo and refurbished his castle into a large scale which had
gardens, a tea arbor and many rooms.

There remain stone walls around the site of the front gate. A recent survey reveals that the
construction materials including the stone steps were diverted from tombstones in Buddhist
grave-yards which the lord had demolished. The fact indicates the religious situation in those
days when Christianity was flourishing. In 1982, the location of the ruined castle was
designated as a National Historic Site.
