The Hakone Open-Air Museum is a cool spot to check out if you're into modern and contemporary sculpture. With around 120 awesome pieces by top artists, it's like a giant outdoor art gallery. They've got a Picasso Pavilion and even a Symphonic Sculpture that's all lit up with stained glass – pretty magical! Plus, there's a new chill-out area called PockeT for when you need a break. So, if you're in the area, swing by and soak up some artsy vibes at this rad museum!
