When drinking sake with friends or colleagues, the Japanese often say "Kanpai!" before taking a sip. "Kanpai" means "Cheers!" in English. When saying "Kanpai," it's customary to make eye contact with the people you are drinking with and raise your glass slightly to show respect and appreciation. It's important to note that in Japan, it's considered impolite to pour your own drink, so it's common to pour drinks for others and wait for them to pour yours in return.
