Japan - How to purchase ticket for Doraemon Museum?

I live in the US and planning on going to Japan. Per their website (http://fujiko-museum.com/english/ticket/), the tickets are sold only at Lawson in Japan and for 3 month advance purchase.
Anyone knows how I can purchase the tickets from outside Japan?
Thanks.

Looks like you might be able to purchase online if your Japanese is good:

You should check with JTB in the US. I purchased a ticket for the Ghibli museum in Tokyo through them and it is also one of those tickets you can buy at Lawsons 3 months in advance.

I'll link to the site I bought my Ghibli ticket from since it gives the phone numbers and e-mails of their offices. Doesn't hurt to check. (I bought mine from Toronto since there was none close to me and they sent it my mail).

Unfortunately, I can't read or speak Japanese. Might try to call JTB and see if they do sell it here, otherwise might take some chances then when I'm over there.
Thanks.

Seems you should be able to reach into a fourth dimensional pocket and pull one out.

I want to use the door, much faster.

Looking at the availability on their website, weekdays have tons of availability. Weekends and holidays are quite full though. It'll be a lot easier to just buy it in Japan.

If you want to buy it in Japan, go to this website:

Click on the part with the random machine (looks like a red ATM) and 3. Print out the page and just bring that part. Write the date in numbers (so April 18th becomes 4/18). Go to any Lawson in Japan and show it to the staff and they'll help you. They're not going to complain or hassle you about this unless the staff is rude and the place is busy.
