Washington Post, Feb 10, 2016 (emphasis added): Five years after nuclear meltdown, no one knows what to do with Fukushima… one huge question remains: What is to be done with all the radioactive material?… Tepco has built a 1,500-yard-long “ice wall” around the four reactor buildings… however, Japan’s nuclear watchdog blocked the plan, saying the risk of leakage was still too high… [M]ost problematically, there’s the nuclear fuel from the plant itself… “The biggest challenge is going to be the removal of the nuclear fuel debris,” [Akira Ono, Tepco’s Fukushima Daiichi superintendent] said. “We don’t even know what state the debris is in at the moment.”… one of the options the government is considering is building a nuclear waste dump under the seabed, about eight miles off the Fukushima coast… Many groups… staunchly oppose the idea of burying the radioactive material at sea in such a seismically active area. “At some point it would leak and affect the environment,” said Hideyuki Ban, co-director of the Citizens’ Nuclear Information Center.

Japan Times, Feb 20, 2016: NRA commissioner suggests plan to remove all fuel debris at Fukushima plant may not be best option — A Nuclear Regulation Authority commissioner has suggested that removing all fuel debris from reactors at the meltdown-hit Fukushima No. 1 nuclear power plant may not be the best option. “I wonder if the situation would be desired that work is still underway to extract fuel debris 70 or 80 years after” the nuclear disaster, NRA Commissioner Toyoshi Fuketa told reporters Friday. “There are a variety of options, including removing as much fuel debris as possible and solidifying the rest,” he added… Fuketa said that unlike the disaster at the Chernobyl nuclear power plant, it is “not realistic” to construct concrete buildings to cover reactors at the Fukushima No. 1 plant because the situation is different. The commissioner also questioned whether construction of an underground ice wall around the reactor buildings to prevent radioactive water buildup will prove effective.
