Have you ever taken a photo of your audio guide? I never had—until now. The German Pavilion at Expo 2025 in Osaka, “Wa! Germany,” may not have been an architectural showstopper, but it delivered something arguably more valuable: genuine fun.

What made the experience special was “Circular,” a tiny mascot inspired by Japan’s kawaii culture. This cheerful guide lights up when held to marked spots and starts talking—bringing the exhibition to life room by room. I found myself genuinely enjoying the interaction, something I can’t say for most museum audio guides. Circular isn’t just cute; it’s effective. The character leads visitors through a thematically clear and immersive exhibition on circular economy—complete with circular building design, recycled materials, and a narrative that’s as playful as it is instructive.

In “Circular Me,” one of the rooms, visitors are encouraged to reflect on their own role in the circular economy. The exhibition is cleverly staged, emotionally accessible, and thoughtfully designed. Unlike many Expo displays that lean heavily on technical jargon or generic messaging, this one is surprisingly engaging.

The German Pavilion follows a successful concept—smart, playful, and visually compelling. “Wa” by the way, stands for more than just a name. It nods to the Japanese word for harmony, and in this case, reflects the pavilion’s core message: that circular economy isn’t just a technical solution, but a cultural shift—toward cooperation, balance, and sustainability.

As much as I appreciated the clarity and creativity, I found myself asking: Is it all a bit too much? There’s a pavilion song. A café. A fan shop. A virtual expo. A stage program. And this is just the German Pavilion, one of around 80. Do we need all this? Or does the overload risk distracting from the core message? When does the immersive become excessive?
