Why It’s Popular in Japan (Local Perspective)
In Japan, anime collaborations are not always about big events.
Instead, fans enjoy:
- Collecting limited items (推し活 culture)
- Participating in small but frequent events
- Competing in game-based collaborations
Especially for Kaguya-sama, the appeal is:
- Strong character popularity (Kaguya / Miyuki / Chika)
- Easy integration into games and campaigns
- Continued fan activity even after the anime aired
👉 Even without a new season, the series stays “alive” through collaborations.
Travel Tips for Overseas Fans
If you’re visiting Japan expecting a “collab cafe,” here’s something important:
- There are no confirmed official cafes or exhibitions (2025–2026)
- Most events are:
- Online
- App-based
- Spread across local shops
What you CAN do:
- Visit card shops (for TCG events or leftover goods)
- Check anime stores like Animate or Gamers
- Follow official X accounts for real-time campaigns
👉 Japanese anime culture often rewards being in the moment, not just visiting locations.
