As I understand it, there are two options for getting tickets to the Ghibli museum: through a local travel agency before we get to Japan, or at a Lawson's convenience store after we get to Japan.
I just enquired at JTB, the only US travel agency that sells these tickets here in the US. It turns out that in addition to the 1000 yen (12 USD) ticket price, they charge an extra $5 for each ticket, plus $10 for shipping. For two tickets, this is a 83% markup. Yay monopolies!
On the other hand, if I wait until I get to Japan to buy them, I worry that tickets will be sold out, since I'll be buying them on the day of the visit.
Should I be worried, or are tickets generally available even right before visiting? I'm thinking of going on a Monday (April 9).
I'd be particularly interested in hearing from people who bought tickets on short notice. How much time in advance did you buy your tickets, and was it during a peak season/weekend?
