When my children (17-22yr old) told me they wanted to go to an anime museum I was very skeptical. I don't watch anime and didn't really care about it. However, it was a trip with two of my daughters so I agreed to go with them.
I found the Ghibli Museum far more interesting than I expected. Yes, for those who like the characters and movies and such there is a special thrill, but the Museum is more than a place for Ghibli fans, it's a celebration of the art of film and animation. Watching film go through machines and get projected in various ways was interesting. Further, going through an artists "office" was far more interesting than I expected. I just wish there was a lot more explanation in English. However, it was fun to guess what was explained and asking my daughter if I got it right.
The Museum is a first class location. Comfortable (finding places to sit in Japan isn't easy!) nice bathrooms, beautiful building and decorations. We were there for almost 3 hours, FAR longer than I expected!
At about $10 US, it's one of the better values available. Getting tickets was easy as I have a daughter living in Japan, but I'm told they are easy to buy online. Get them early, as they only allow so many, and your visit has a time window on arrival - although we arrived 30 min early and they let us in. Easy to get to via public transportation, a big park is next to the Museum so we walked from the train station.
Photos are not allowed inside. They have a bookstore, and gift shop that were doing VERY brisk business the day we visited. There is a slight bias for younger children, but my kids had a blast.
A final bonus -- you exchange your entry voucher for a "Ticket" which is actually a real piece of Ghibli movie film, mine had 3 frames on it. It's the only ticket of our 2 week trip I saved.
It was an unexpected surprise, I'm glad I went!
