Interesting properties of the entropy function
Update 2017-07-03: Corrected equation for associative definition, thank you /u/Syrak. This may not be the first time someone recognized this, but I have recently discovered some interesting and useful properties of the entropy function and now share them. First a definition: Entropy — H(p 1 , p 2 , ..., p n ) — is a function that quantifies surprise in selecting an object from a set where the probability of selecting each object is given: {p 1 , p 2 , ..., p n }. This has utility in communications, information theory and other fields of math. H b (p 1 , p 2 , ..., p n ) = Σ(i..n)-p i log b (p i ) where b is normally 2, to express entropy in bits. Other definitions of H() use expected values and random variables. As an analog to the definition above, I will discuss entropy of a set of frequencies. p i = f i / Σ f i. Entropy defined without bits: A definition that doesn't use bits is: H(p 1 , p 2 , ..., p n ) = Π(i.....

Me, my boss and a guy from Singapore office were the only non-Japanese in that room of 60+. All others were men on overseas assignment from Tokyo home office.
Same rules here as for other trading floors: lunch eaten at desk. At IBJ, a woman with a wheeled cart arrived at 11:30am daily, quickly traversing the aisles between the long rows of trade stations, collecting money, serving meals. Soon the raised-floor room was filled with the sound of noodle slurping, soup bowl draining, lip smacking and burping at will.
My co-workers were fastidiously polite and tidy, But their culture considered "silent eating" to be bad manners (was a sign that the food wasn't enjoyable or good). It is impossible to make that volume and variety of noise without some amount of open mouth activity.
So in answer to your question, "yes". In the U.S.A., I saw Japanese i-bankers eating with their mouths open, en masse, on a daily basis. It was very normal behavior at IBJ.
