Park or museum Ghibli in Japan - what is more interesting?
We visited the museum. It is small, but we liked it. We didn't go to the park, so I can't compare.
The museum, and then the park. Everything is interesting if you like the studio's creativity.
The museum is considered a must-visit place for fans of Miyazaki.
By the way, taking photos there is prohibited, unless done sneakily)
Usually people go to the park when they fail to get into the museum or miss getting tickets.
