9) Don’t use the opposite end of your chopsticks to take food from a communal plate
Since the backsides of the chopsticks are where your hands rest, it’s actually not a very clean area and shouldn’t be used to pick up food. Asking the waitstaff for an extra pair of chopsticks or politely saying, jika bashi de shitsurei shimasu (excuse me for using my own chopsticks), and taking food using your chopsticks is actually the proper thing to do.
10) Never raise your food above your mouth
Many people raise their food to about eye level while saying, itadakimasu before eating. However, proper etiquette states that you should never raise your food above your mouth, the highest level your chopsticks ever reach.
