If you're a Harry Potter fan looking for an immersive experience without the crowds, the Harry Potter Studio Tour in Tokyo is a must-visit. This indoor theme park and museum is spacious enough to offer a wide range of activities, making it a perfect destination for a hot or rainy day. The best part? The crowd is minimal, which makes for a more relaxed and enjoyable visit compared to other popular tourist spots. I highly recommend booking through Headout, as their ticketing service is incredibly convenient. Unlike other platforms, they offer a 12:00 PM timeslot, which tends to sell out elsewhere. Overall, it’s a magical alternative to the usual touristy attractions.
