Let's make this birthday one to remember.

91 years old (Born on April 08, 1934)

Happy birthday to the visionary architect Kisho Kurokawa! Architect of futuristic pods and green-minded dreamer, your designs still turn heads quicker than a spinning capsule in Tokyo's Nakagin Tower. Your iconic Metabolist ideas taught us buildings could grow organically—a concept we're pretty sure made even concrete blush.

From avant-garde masterpieces promoting harmony between nature and urban living, to pioneering eco-friendly architecture before it became cool globally—you've always been ahead (or above) trends by decades. May your creative legacy inspire generations more; today we toast you with sustainable cupcakes—biodegradable wrappers included—and celebrate until our modular capsules spin dizzyingly fast!
