Studio Ghibli Museum tickets

Hi there! I was a little confused because I saw someone suggesting another user consider going to the Studio Ghibli Museum in November and the way the phrased it made it sound like tickets for November hadn't gone on sale yet. Is this correct?

Availabe 3 months out from the 1st of the month.

November probably already sold out. Check the sellers.

Ticket sales vary depending on which reseller;

JTB = from the first of each month for the following four months (for example, tickets for June 1 through September 30 go on sale on June 1) = Tickets for November already on sale

Lawson Online = from the tenth of each month for the following month (for example, tickets for July 1 through July 31 go on sale on June 10) = Tickets for November not yet on sale (https://l-tike.com/st1/ghibli-en/sitetop)

Read the official web first.
