When we were visiting Ueno Park, there happened to be having a peony festival. Admission was 600 yen, totally worth checking out. I imagine they probably have it on an annual basis in early May. Inside this part of the park, it is covered by a lot of taller trees so even on a sunny day, we didn’t feel hot at all. Plus there is a little food stall that sells traditional mochi dessert and my favourite amazake（甘酒）. Just can’t get enough!
