KYOTO — Their region having played host to three Group of Eight ministerial conferences over the past month, many in Kansai are breathing a sigh of relief and hoping the security measures that residents, and even summit participants, found excessive are now in the past.

But human rights activists warn the heavy police presence and security checks seen in Kansai are setting a dangerous precedent for next month's G8 summit in Hokkaido and future international events throughout Japan.

In May, Kobe hosted the G8 environment ministers meeting amid unusually tight security.
