Here it is: the various JDF and JMSDF uniforms and weapons.

Japanese JMSDF have adopted the M4 Carbine, 5.56 mm, M4 which is considered a "special forces" weapon. US Marines are already considering moving on to a more advanced M27 Infantry Automatic Rifle but still use the M4.

The Japanese make some of their own weapons but often under license from US or European companies. They don't currently have a huge weapons industry like the US and Europeans.

The JMSDF pattern seen in the CB photo is most likely the Type III Flecktarn camouflage which is widely adopted by the Japanese military. They actually don't have separate services like the US. The JMSDF provides US Marine like support to the Japanese Navy which all comes under the JMSDF -  Japan Maritime Self-Defense Force.

Note: In the US the word Marine is always capitalized. They are NOT soldiers.
