Yes, it is widely considered safe to eat seafood in Japan in 2026. Following the 2023 release of treated water from the Fukushima Daiichi plant, the Japanese government, in conjunction with the International Atomic Energy Agency (IAEA), has maintained a rigorous, transparent testing program. Data from early 2026 shows that the levels of tritium in seafood remain significantly below the safety thresholds set by the World Health Organization. In fact, by November 2025, China officially resumed seafood imports from Japan, signaling a major international restoration of trust in Japanese food safety. Most seafood found in Tokyo’s Tsukiji or Toyosu markets comes from the northern Hokkaido region or the southern waters near Kyushu, which were largely unaffected by the local Fukushima currents. For extra peace of mind, you can look for "Certified Safe" labels provided by local cooperatives, but for the vast majority of tourists, the quality and safety of Japanese sushi and sashimi remain among the highest in the world.
