In a slightly surreal case, Kyodo news agency reports April 20 that a Shanghai Maritime Court ordered the seizure of a vessel owned by Japanese shipping giant Mitsui OSK Lines at a port in Zhejiang province for failing to pay compensation in "a wartime contractual dispute." It seems that in 1936, Mitsui's predecessor, Daido Shipping Co, rented two ships on a one-year contract from China's Zhongwei Shipping Co. The ships were commandeered by the Imperial Japanese Navy, and later sank at sea. The suit was brought against Mitsui by grandsons of the founder of Zhongwei Shipping, and has been batted around in China's courts for years. In 2012, the Supreme People's Court rejected Mitsui's petition for retrial, affirming the Maritime Court's finding that the company must pay. The decision to seize the ships now seems pretty clearly retaliation for Japanese cabinet minister Keiji Furuya's visit to the Yasukuni shrine days earlier. Prime Minister Shinzo Abe himself sent a "ritual offering" to the shrine ahead of Japan's spring festival, which starts this week. All of this is happening (again less than coincidentally) exactly as Japan has started construction of a military radar station on Yonaguni Island—just 150 kilometers from the disputed gas-rich Senkaku archipelago, claimed by China as the Diaoyu Islands.

While the world media are paying little note, and most of the stateside public thinks of the Fukushima disaster in the past tense, in fact the ongoing effort to stabilize the stricken nuclear complex is now about to enter its most dangerous phase. Tokyo Electric Power Co (TEPCO) will this month begin removing fuel rod "assemblies" from reactor building No. 4—where they are vulnerable because the containment dome was shattered by a hydrogen explosion four days into the disaster, on March 15, 2011. They are to be transferred to an "undamaged facility" within the complex. There are 1,533 of these zirconium-plated "assemblies," and they are said to be in a chaotic "jumble." The transfer is to take about a year—if all goes well. (Japan Times, FukuLeaks, Nov. 14; EneNews, Nov. 6; Fukushima Update, Sept. 14)

A Japanese appeals court is expected to rule soon in a suit filed on behalf of 14 children by their parents and anti-nuclear activists in June 2011 in a district court in Fukushima arguing that the nearby town of Koriyama should evacuate its children to an area where radiation levels are no higher than natural background levels in the rest of Japan, or about 1 millisievert annual exposure. After the Fukushima accident, Japan set an annual exposure limit of 20 millisieverts for determining whether people can live in an area. The average radiation for Koriyama is below this level, but some "hot spots" around the city are above the cutoff. The district court rejected the suit in a December 2011 decision. An appeal is now before the Sendai High Court in nearby Miyagi prefecture.

With all eyes on the crisis between North and South Korea, the international media have largely overlooked growing tensions between both Koreas and Japan. On April 5, Seoul lodged a diplomatic protest against Japan's renewed territorial claim to the Dokdo Islands, known as Takeshima in Japan. The protest came after Tokyo issued a formal claim over the Seoul-controlled easternmost islets through approval of a diplomatic report that stated: "Takeshima is clearly Japanese territory in light of historical facts and under an international law." In a separate protest days earlier, Seoul lodged a complaint over new textbooks approved in Japan that emphasize Tokyo's claim to the islets while downplaying Japanese wartime atrocities in Korea. (Dong-a Ilbo, April 6; Xinhua, April 5; AsiaOne, March 27)

Contractors could be illegally dumping radioactive soil, vegetation and water into rivers and open areas near the stricken Fukushima No. 1 nuclear plant, Japan's Environment Ministry admitted Jan. 4. The ministry said it will summon senior officials from companies contracted by the Fukushima Office for Environmental Restoration to answer questions on how they manage contaminated waste following claims of illegal dumping in the coastal town of Naraha, the evacuated village of Iitate, and the inland in the city of Tamura. Under a law passed in the wake of the Fukushima disaster, illegal dumping of contaminated substances may be punishable by up to five years in prison or a fine of up to ¥10 million. "It is very regrettable if that is true," Fukushima Gov. Yuhei Sato said of the suspected dumping at his first news conference of 2013. (Kyodo, Jan. 5)

Japan scrambled  fighter jets on Dec. 13 after a Chinese maritime aircraft entered airspace over the disputed islands known as the Senkaku to the Japanese and the Diaoyu to China. The Japanese defense ministry said the incident was the first violation of Japanese airspace by a Chinese official aircraft since 1958. "It is extremely deplorable," said Osamua Fujimura, Japan’s chief government spokesman. Kyodo News quoted Japan's Chief Cabinet Secretary Osamu Fujimura that the plane belonging to the Chinese Oceanic Administration was spotted near the Uotsuri Island at 11:06 AM local time, and Japan's Air Self-Defense Force responded by dispatching F-15 jets. The response was of course prosted by Beijing. Foreign Ministry spokesman Hong Lei  said: "Flying a marine surveillance airplane in airspace above the Diaoyu Islands is completely normal. China urges Japan to stop illegal actions in the waters and airspace of the Diaoyu Islands. The Diaoyu islands and affiliated islands are part of China's inherent territory. The Chinese side calls on Japan to halt all entries into water and airspace around the islands." (Japan Today, FT,  BBC News, Dec. 13)

Following disturbing findings of thyroid growths in children of Fukushima prefecture, Japan's Environment Ministry this week began thyroid gland tests on children in Nagasaki prefecture, across the central island of Honshu to the south. Those children will serve as a control group for kids undergoing similar tests in Fukushima prefecture. Fukushima's prefectural government one year ago launched what it intends to be a lifelong thyroid gland test program for 360,000 children who were aged 18 or under when the disaster began in March 2011. The Fukushima screening have been conducted on 115,000 children—about one third of the total number of children that will require testing. In July, it was revelaed that over 35% of the 38,114 then screened were found to have abnormal thyroid growths.
