Japan's Prime Minister, Fumio Kishida, has called on China to ensure that its people act in a calm and responsible manner after incidents of stones being thrown at diplomatic missions and schools. These incidents followed the release of wastewater from the Fukushima nuclear plant. China had recently banned all seafood imports from Japan as the country began releasing cooling water from the plant, an operation that both Tokyo and the United Nations' nuclear watchdog deemed safe. In response to the attacks, Japan has increased security around schools and diplomatic missions and has urged its citizens in China to keep a low profile. Additionally, businesses in Japan have been inundated with nuisance calls from Chinese numbers, some of which contain abusive and racist language.

Prime Minister Kishida expressed regret over these incidents and summoned the Chinese ambassador to strongly urge him to call on Chinese citizens to act responsibly. Japan's Deputy Foreign Minister, Masataka Okano, further emphasized that China should provide scientific evidence and inform the public accurately to avoid unnecessary concerns. In response, China's Foreign Ministry spokesman, Wang Wenbin, assured that China protects the safety and rights of foreigners in accordance with the law. However, China urged Japan to cease discharging nuclear-contaminated water, consult with its neighbors, and dispose of it responsibly.

Japan's Foreign Ministry has advised its citizens in China to be cautious in their speech and behavior, while also approaching Japanese embassies, consulate generals, and schools with vigilance. They are also advised not to approach protests or take pictures with their smartphones. Examples of harassment calls targeting Japanese businesses have also surfaced, with social media users in China even posting recordings and videos of such calls. Meanwhile, Japan has begun releasing diluted wastewater from the Fukushima plant into the Pacific Ocean.

The released water has undergone filtration to remove all radioactive elements except tritium, which is within safe levels and lower than what is released by nuclear power plants during normal operations. Test results from seawater and fish samples near the plant have confirmed the safety of the process. The United States has expressed satisfaction with Japan's scientifically justified and transparent process. In a gesture of support, US Ambassador to Japan Rahm Emanuel plans to visit Fukushima and publicly consume locally caught fish.
