It is one of the mysteries of Japan's ongoing nuclear crisis: How much damage did the March 11 earthquake do to the Fukushima Daiichi reactors before the tsunami hit? The stakes are high: If the quake structurally compromised the plant and the safety of its nuclear fuel, then every other similar reactor in Japan will have to be reviewed and possibly shut down. With virtually all of Japan's 54 reactors either offline (35) or scheduled for shutdown by next April, the issue of structural safety looms over the decision to restart every one in the months and years after.

Anti-base movements are once again rising in South Korea, this time on the southern coast of Jeju Island. With the Jeju anti-base moving growing, it may be worthwhile to take stock of past anti-base movements in South Korea. Keeping the Jeju anti-base protest in mind, this article takes us back to the Pyeongtaek antibase movement episode from 2005-07 with an in-depth look at resistance against the expansion of Camp Humphreys from local residents and outside activists. I examine several questions regarding the evolution and efficacy of the Pyeongtaek movement. How did activists merge and frame a local issue alongside more abstract claims of peace and security? What obstacles prevented the movement from achieving success at the level of policy outcomes? What strategies and tactics did South Korean governments use to respond to anti-base protests? I then return to the struggle on Jeju Island, offering some comparisons and reflections on the possibilities which lie ahead for this growing movement.

The radioisotope centers of the University of Tokyo at twenty-seven locations are responsible for protection against radiation and conducting decontamination work. As a physician of internal medicine, I have been involved for scores of years in decontamination, among other locations, at radiation facilities of the University of Tokyo Hospital.
