Yeah, sorry.

In Japan, when someone does something where they don't want to be recognized, one typically wears a hood and medical facemask (and maybe sunglasses for a 'total sketch' look). Even without the glasses though, this makes one tough to pick out. Medical facemasks are worn regularly in Japan by people of all ages; high population density makes cold/flu spread very easily. There is much controversy as to whether this is in anyway effective but people do it anyway. So, wearing a mask hides your identity pretty well, but it's socially acceptable. Putting a hood up on top of that though, crosses some vague line in the Japanese mind. Haha thats really the only way I can describe it.

Hoodies are pretty popular here. I've never seen anyone use the hood barring a serious snowstorm. Its fashionable, but people dont put them up, unless they are committing a crime. Google 'downtown tokyo in winter'. You'll see facemasks but no hoods.

Anyhow Japan functions largely on image alone, so I was just pointing out that these guys look very sketchy dressed like that, even if its not their intention.

Oh and, it being Tokyo, it hit 9 deg C today. Its not that cold here.
