The best place to celebrate Halloween with kids in tow is at Sanrio Puroland. Here you can enjoy the theme park's kitschy Halloween ambience at noon and its spooky events in the evening. After taking adorable souvenir photos with Hello Kitty and My Melody in their cute Halloween-style costumes during the day, the whole park turns into a scary spectacle with plenty of 'horror areas' in the evening.
If you can't get enough of Japan's beloved cat-girl and friends, then stay the whole night from October 27 to 28 (10pm-5am) and celebrate with DJ Hello Kitty, Sky-Hi, Tempalay and more (participants must be aged 20 or older; tickets from ¥4,500).
