Here's a map of the area. Trevor is said to have come in from the east entrance, looks to me like there's a 7Eleven about 50 metres away, and a couple of other convenience store options nearby. Also, not a huge amount of space or buildings to search on base - he has to be inside the perimeter if he wasn't seen leaving again (unless by vehicle).

I think you’ve got the wrong side of the base; my limited understanding is that he was in the East side of Yokota AB so if he left to buy items off-base, he’d have likely used the East Gate. ( here’s a link to a map of Yokota AB

This Google Maps link would show the 3 minute walk if he had exited East Gate at McGuire, turned left to the 7-Eleven.

While he could have also gone to the Family Mart ( turn to his right ) , it’s way longer - 900 m. 7-eleven is only about 200m from the Gate.

It looks like his wife was previously posted at RAF Menwith Hill, so likely working as a SIGINT analyst; that’s the same signals intelligence operation that was exposed / leaked by Snowden FYI.
Anyways, w/r side discussions on why separate bedrooms etc., irregular work hours might explain it even better than some sort of martial issues.
And, as for “Chu Hai” drinks, the usual alcohol content used to be similar to beer - between 3 to 5.5% but these days, the bestsellers are in the 9 to 12% range; the best known brand being Suntory’s Strong Zero ( it’s kind of become a meme , at least with expats in Japan).
The whole bang per buck ( or yen) kinda makes it like a fruity malt liquor ... you can get often get a 500mL tallboy for less than $1.50.
Even doing the math and calculating the total amount of alcohol, drinking 3-4 of these for some reason can kind of kick your *advertiser censored**. Or, at least you feel it the next morning - way more if you had simply drunk 6-8 beers instead.
Although none of the articles didn’t indicate the state of his clothing and shoes when they were allegedly found by his wife, if this was the case, and they had initially been discarded ( rather than neatly folded or arranged ), I can think of at least one uncomfortable reason for someone taking off their clothes. If he took MDMA or a synthetic, one side effect is overheating , combined with psychosis - but if that were the case, and given they searched with dogs, you’d expect a body in the vicinity.
Haven’t posted here for about 3 years or so... good to see this site is alive and well.
