The exhibition has started since December 1st, and will run till February 21st next year. However, during that period, the museum will be closed from December 28th till January 4th. Folks who are interested to go to the event need to plan the schedule of the visit around that period. Admission is free.
Almost all Gundam series are covered, from the original MS Gundam to the most recent Gundam Double O, as well as SD Gundam. Gunpla as the major Gundam product line is of course on display as well. Many never seen before special toys which were released in the earliest days when MG Gundam started airing in Japan were shown as well.
