This article discusses the etiquette and cultural expectations around plates in Japan, including whether or not it is polite to stack plates. It is generally considered rude to stack dishes as it implies that one dish is more important than another and can lead to spills. Instead, dishes are typically presented on separate trays or stands so that each dish has its own space and importance. Stacking plates may be allowed in certain situations, such as at casual eateries or when all guests agree to have their meals mixed up due to limited space.
