The Art Aquarium is no well-kept secret, so on the weekends it gets! The JAPANKURU team got there 30 minutes before opening on a Sunday, and the line of people waiting was already 50+. If you're in Japan on vacation, we heartily recommend you try going on a weekday, and avoid the Japanese summer holidays that center around Obon if you can (around August 10~18). Of course, if you really want to take some fantastic shots of the exhibition with no people in the background, you can spring for a priority ticket. (Admission is 1,000 yen, priority 2,000 yen.) You'll still want to get there before things open, in that case, since the priority just springs you to the front of the line.The event is actually tied up with a number of other things going on in the neighborhood, so make it a whole day out! You can see the informational pamphlet, in Japanese, right here . For one, the ticket (or just wearing a yukata) will give you discounts on a few things within Coredo, the mall that contains the exhibition hall. Our favorite promotion was the free photo print you can get just downstairs. Take a cool picture at the exhibition, post it on instagram with the hashtag #コレドの夏 (Coredo summer!), and get your print with a special goldfish digital frame from a machine in the 4th floor Muji. Afterwards, head out of the mall and back onto the streets: nearby is the Fukutoku Shrine, where you'll find a very summery display of little Japanese wind chimes.Or, if you happen to be as much of a fan of both pokemon and bubble tea as we are, you can take a little stroll to get some themed tapioca drinks in the same neighborhood. The Nihonbashi Takashimaya has a pop-up Hong Kong-style pokemon-centric boba stand in the basement from August 1~13!
