Due to limitations or non-availability of some medical and educational services, personnel who require specialized services should fully investigate the availability of such services prior to transferring to Japan. If you have orders assigning you to an aviation squadron and the orders state that your ultimate duty station is at Yokosuka, contact your detailer immediately. There are no aviation squadrons based in Yokosuka. All aviation squadrons are located at NAF Atsugi.

If you received "unaccompanied" orders to Yokosuka, please do not bring your family. You will not be eligible for certain entitlements, allowances or family services; this could cause an extreme financial hardship. There are many other issues that you must consider before coming to Japan, so do your research and gather your information as soon as possible. We are all guests in Japan and we're all ambassadors.  We should conduct ourselves with honor, courage, commitment and respect to others.  

Drinking and Driving in Japan - This is punishable offense with serious consequences like monetary or imprisonment.

Plan ahead when bringing your pet (dog or cat). The quarantine process is lengthy and shipping pets are costly. Availability for on-base housing is limited and it may cost a bit more for off-base housing that allow pets. It may delay your move. 

Refrain from bringing large furniture because some Japanese housing are small.

Defense Service Network (DSN) Dialing Instructions

The DSN is the provider of long-distance communications service for the Department of Defense (DoD). Every installation has a special DSN number and the numbers vary by world-wide location. In order to place a call using DSN, the caller must be using a military phone on an installation. Cell phones cannot dial DSN numbers. When dialing a DSN number from a United States installation to another United States installation, it is unnecessary to dial the DSN 315 area code. When dialing a DSN number to/from overseas locations, the DSN area code must be included.
