Today I got up early to go to Koya-san, a small town in the mountains near Osaka, filled with Buddhist temples and shrines.
Koya-san was declared a UNESCO world heritage site in 2004; I wonder if they were a bit slow to classify it, seeing as some of the temples have been around since the twelfth century. Still, I suppose there was no real rush: if the buildings had been there for that long, they could wait a few more years.
Although since the Kondo temple "has been repeatedly destroyed" according to our pamphlet from tourist information, perhaps it's best not to delay these things.
