Since the 1980s, they have been producing classics like My Neighbor Totoro, Howl's Moving Castle, Laputa:Castle in the Sky, Kiki's Delivery Service, Nausicaa and Graveyard of the Fireflies.
If you have not, then you might want to watch this short compilation for a quick overview of the genius of Hayao Miyazaki and his Studio Ghibli films.
Ghibli Museum is located in the city of Mitaka, about 15 mins out of Tokyo by rapid express train. To gain entrance to the Museum, an advance ticket purchase is required. Strangely, the tickets can only be ordered through the Lawson convenience stores using their Loppi ticket machines! For those who can't read japanese, it can be quite intimidating I tell you, but luckily, the Lawson store clerks were only too happy to help out bewildered gaijins like me!
