Field Notes

Ahoyama Castle is on the opposite side of Tsubokasayama Castle from Mikoshiyama Castle and is what you would reach first if you were taking the main trail up from the town. There is a large cleft in the mountainside that splits the mountaintop Ahoyama Castle from Tsubokasayama Castle. I have read other accounts that say there are no discernible ruins at Ahoyama Castle, but from my perspective I really think some of the largish stones strewn about may be from some stonework remains and are similar in size and shape to those found at Tsubokasayama and Mikoshiyama. There also seems to be a couple small baileys on either side and possibly an obikuruwa Bailey too. I have seen one photo of an illustration of this castle from a seminar in Otsu (?) so I think I need to make a trip to the Otsu City Musuem at some point to see if they have any more materials on both these sites.

There is no actual trail up to Ahoyama Castle. Some don't recommend trying it but I managed. Just find a place to scramble up the side and once you hit the ridge it's not so bad. Regarding the name Ahoyama Castle, old records say「あほ山」without kanji so it was likely originally ahoyama. It seems that at some point it was given the kanji 青山 which would be read Aoyama but I really did not dig into the history of the name any more.
