The U.S. Navy has banned drinking for all of its personnel stationed in Japan.
The move comes after several U.S. military-related incidents on the island of Okinawa, the most recent one being an alleged drunk-driving crash on Saturday.
Japanese media reported an American sailor with a blood-alcohol concentration six times the "permissible level" crashed head-on into two vehicles.
The Navy's statement doesn't set an end date for the drinking ban, which is imposed both on- and off-base. Sailors will even have their freedom to travel off-base restricted until "face-to-face training has been conducted" by officers.
Roughly 50,000 American military personnel are stationed in Japan, with half based in Okinawa.
However, locals in Okinawa have long protested the U.S.' military presence, and the situation gets worse every time an American soldier is suspected of a crime.
Last month, just a week before President Obama was scheduled to visit Japan, an American military worker was arrested on suspicion of dumping a 20-year-old Okinawa woman's body.
As The New York Times points out, some crime statistics show American personnel in Okinawa are arrested at lower rates than locals.
The U.S. doesn't want to anger Japan, one of its greatest allies. Some have argued that American bases in Japan aren't only strategic, but necessary.
