Ariake GYM-EX

Multi-purpose events center

Ariake GYM-EX is a multi-purpose venue that was originally built for gymnastics events, but has branched out to hosting various things. It's about 5 minutes on foot from Ariake-tennis-no-mori Station (Yurikamome Line) so there's a level of convenience if you're visiting via public transport. It hosted a big stationery fair over the weekend, and I feel like it was a great venue for that purpose!
