Ueno Park in Tokyo is one of the most popular parks in Japan for many reasons. We walked the park for hours and could have easily spent a few days here. There was so much to see and experience from museums, pagodas, shrines and temples. Ueno Park is also the most active cherry blossom attraction with over 8,000 trees. We were here in February just as the trees began to blossom, so we missed the park in full bloom, but what we did see was so incredibly beautiful.
