1. ((send)) a year-end present
    Seibo is the yearend gift-giving season, and may also refer to the gifts themselves. At the end of the year, it is the custom to give gifts to people with whom one has a relationship, such as relatives, bosses, customers and friends. Each gift expresses appreciation for the help received during the past year and acknowledges a continuing relationship, although it cannot be denied that the practice has become a formalized one. There is one other similar gift-giving season called chugen, which falls in the summer.
