On the 6th floor of “Animate” in Akihabara, a museum dedicated to “Hanamayata” will be open to the public from the 18th of July until the 16th of August.
Original character designs and so on are on display. The exhibition also includes merchandise such as CD, manga, Blu-ray, etc…
If you go to the 1st floor, take a picture of the Hanamayata vending machine and twit about it to Twitter, you could get a special postcard!
