“We should not be out shooting fireworks. We should not be out having large celebrations and parties while the Okinawan people are in mourning. If we really believe we are part of the Okinawan community, then we too must be in mourning. And we do,” Lt Gen Lawrence Nicholson said at a news conference at a US base in Okinawa.
The 30,000 US troops will not be allowed to drink alcohol off-base, and visiting clubs and bars is prohibited. Upcoming festivals and concerts on bases are being postponed until later in the summer. The restrictions took effect on Friday and will last until 24 June.
