[Japanese]
The base of the large cross is Daiōzaki (大王崎) in Ise (伊勢),
and the intersection is Kamijima (上島/神島) in Ehime Prefecture, where there is Mt. Furuhousan (古法皇山).
The tip of the cross is Mt. Misen (弥山) in Miyajima (宮島).
The names of the places are meaningful names respectively.
And... where will the tip end up?
Oh, wow... It will end up exactly Chang'an (長安) of China, present-day Xi'an, where Master Kukai (空海) lived to learn.
And then it will go straight to Lake Galilee in Israel.
"We are from Israel!"
"I've learned that lesson from Chang'an!"
I think they say so.
As for the central cross, the end is towards the Vatican (Rome).
As for the small cross, the end is .... towards the Quianshan (千山), Anshan (鞍山), in China.
And at the intersection of the small cross, a human face is sculpted, with the inclination of the cross exactly the same.
Master Kukai had me draw a total of the three crosses.3本の十字架
