technically, jap or ppl with 4 season hv very sensitive temp feel, once wind blow, they feel cold. so they will wear very thick to keep warm.
for us, our body generate heat more, so when in cold place, our body will work hard to maintain.
if we feel cold, they will feel colder. but they r used to cold esp the nite. we r nt.
n then the 'ai sui mai mie' is also another prob. some die die mid winter still wanna wear mini skirt, while some wear til like snowman.
for tokyo, the wind is the essential part. can be very cold one day, hot another. in train n mall, got heater, so they will jus take out coat. for us who r sensitive to heat will feel uncomfortable n sweat loh.
hahaha!!
