this site, I guess this may be the Potanthus flavum.
I also found a butterfly pupa near the exit gate - it looks like a Mycalesis species.
On 18 June, we went to the Kiyomizu-dera temple (清水寺) and Yasaka Shrine (八坂神社) which are just a few bus-stops away from our hotel at the foot of Mt. Higashiyama.
As we walked around the hill, we saw a Sailor-type butterfly perching in front of us. I think this may be the Neptis pryeri
