Frequently asked questions

How do I find events for today or the weekend?

Choose Today, This weekend or Next weekend. Events across Tokyo are shown by default. Choose a core category, or open More filters for area, ages and fees.

Can I find indoor events for a rainy day?

Open More filters and choose Indoor. Outdoor events carry a rain-cancellation note when our listing specifies one. Severe weather can affect indoor events too, so check the latest notice before leaving.

Where can I check fees, booking and age requirements?

Open Event details to read the time, venue, ages, fees and participation instructions here. Booking and lottery requirements are also highlighted on the card. Use the official link within the details when you need to apply or check last-minute changes.

Can international families read the listings in other languages?

Switch between Japanese, Chinese, English and Korean; on mobile, language choices are in the menu. Some source details remain in their original language. A translated listing does not mean the event offers that language—check the organizer’s information if you need English or interpreting support.
