Hello!- from SIC
Bounen-kai (Yearend Party) ⇔ Shinnen-kai (New Year Party)
Bounen-kai is held at the end of the year to forget whatever difficulties and unpleasant events that happened in the year by drinking and having fun.
When December comes, it is planned by company employees and friends. At this time of year, many restaurants can be fully booked especially on Fridays and Saturdays. People like to go to second party, third party.
Be prepared for drinking: ・holding one's liquor... Many Japanese people try to let you drink liquor because it is believed to be a good manner. ・Keep a rank relationship between boss and you, even if they say "let's be frank　today". ・Drink supplement of turmeric before you drink...it prevents getting sick from drinking too much. ・preparing a special party stunt like singing songs, telling jokes, small magic or imitating someone ...People will love it.
Control yourself and Enjoy!!
