Must-try Okinawa food: the Blue Zone diet

Short answer: try goya champuru (bitter melon, tofu, pork, egg), Okinawa soba (thick wheat noodles, pork broth), rafute (braised pork belly), taco rice (US-military fusion), umibudo ("sea grapes", briny seaweed). The diet is famously plant-heavy—Okinawa is one of five Blue Zones with centenarians.

Goya champuru: Bitter melon (goya) stir-fried with tofu, egg, and pork. The bitterness is an acquired taste; many visitors love it. High in vitamins.

Okinawa soba: Thick wheat noodles (not buckwheat) in a pork broth with sliced pork, kamaboko, and egg. Comfort food, found everywhere. Cost: $8–$12.

Rafute: Slow-braised pork belly in a soy-sugar sauce. Rich, tender, and falling-apart good. Often served with soba or rice.

Taco rice: A US-military-era fusion: taco meat, cheese, lettuce, tomato over rice. It sounds odd; it’s unexpectedly popular and good.

Umibudo: "Sea grapes"—a briny, popping seaweed served as a side or salad. Acquired taste; try it once.

Blue Zone diet: Plant-heavy (sweet potato, legumes, greens). The local principle "hara hachi bu" means stop eating when you’re 80% full. No large portions; intentional eating. Okinawa centenarians credit this to longevity. Awamori (local distilled spirit) is drunk in moderation at dinner.
