I think foreign residents in Japan actually seem on average to be better users of chopsticks than the Japanese, although I have absolutely no data to back up that claim, nor a similar claim that most foreigners’ chopstick skills outdo Japanese’s cutlery skills. However, there are a multitude of finer points of etiquette regarding these implements that may not be familiar to many of my readers, nor to me for that matter, so to see what faux pas our hosts may be looking out for, or indeed doing themselves, let’s look at a couple of surveys from goo Ranking on bad chopstick habits people have and bad manners in others that they can’t help noticing. Both surveys were conducted between the 20th and 24th of July 2007.
For me, in Q1 I do 1 rarely, 2 a bit with soba, and 5 sometimes. One manner not noted is rubbing the ends of your sticks together to get rid of splinters, which is apparently an insult to the restaurant or host that you think their chopsticks are cheap and splinter-prone.
