Found on the National Museum's ground floor, this store carries a whopping 4,500 items at all times – from paraphernalia related to ongoing exhibitions to original products themed on works from the museum's permanent collection. You'll find bags, stationery, accessories, replicas of famed artworks...all superb souvenir options. The art book section is almost like a small library and stocks illustrated tomes recounting past exhibits alongside books published by the museum. It's easy to lose track of time and spend an entire day browsing here. On your way out, make sure to try one of the capsule toy vending machines that dish out quirky collectibles – we love the replicas of Haniwa terracotta figurines from ancient Japan.
