Japan (nationwide; formal etiquette codes developed Muromachi and Edo periods; everyday customs prehistoric)
Japanese dining customs represent one of the world's most codified systems of table behaviour — rituals evolved over centuries of Confucian, Buddhist, and Shinto influences that transform eating into a form of social and philosophical expression. Core customs include: itadakimasu (いただきます, literally 'I humbly receive') spoken before eating, an expression of gratitude to the food, its preparers, and the living things that gave their lives; gochisosama deshita (ごちそうさまでした, 'it was a feast') spoken after completing a meal. Chopstick etiquette prohibits sticking chopsticks upright in rice (funeral imagery), passing food chopstick-to-chopstick (funeral cremation imagery), waving chopsticks over dishes before deciding, or using them to skewer food. Pouring drinks for others before yourself, not starting to eat before the host or the eldest, not lifting heavy dishes (nabe pots) with one hand, and eating rice from a bowl held in the palm are all fundamental courtesies. At conveyor-belt sushi (kaitenzushi), plates are typically not stacked or touching others' plates. At izakaya, never pouring your own drink while others at the table have empty glasses. Restaurant entry and exit customs (irasshaimase greeting, shoes at ryokan, floor seating protocol) complete the system.
Cultural context — etiquette shapes the experience of eating Japanese food; the gratitude and mindfulness embedded in itadakimasu transforms the act of eating
{"Itadakimasu before eating; gochisosama after — both mandatory, both sincere, both directional thanks","Chopstick prohibitions (upright in rice, passing between chopsticks) carry funeral/death connotations","Pour for others before yourself — topping up others' drinks demonstrates attentiveness and generosity","Do not begin eating before the designated elder or host at formal gatherings","Hold the rice bowl in the palm — do not leave it on the table while eating"}
{"Oshibori (hot towel at restaurant arrival) is for face and hands — not the table; hand-wiping only at formal settings","At ryokan kaiseki: the presentation order reflects respect — wait for the appropriate moment to proceed","Noodle slurping is acceptable and even complimentary — signals enjoyment and cools the noodle in transit","At omakase sushi: eating the nigiri by hand (not chopsticks) is entirely appropriate — many chefs prefer it"}
{"Using waribashi (split chopsticks) rubbing together — implies the cheap chopsticks are rough; considered rude","Lifting nabe or heavy dishes with one hand at formal settings — two-hand handling shows respect","Finishing all rice before other dishes at formal meals — rice paced throughout the meal in Japanese dining","Pointing chopsticks at fellow diners — equivalent to pointing a finger in Western contexts"}
