Oseibo is a Japanese custom of gift-giving that occurs at the end of the year, typically in December. It is a way to express gratitude and appreciation to those who have helped or supported you throughout the year, such as friends, family, and colleagues. The gifts can range from food items to household goods and are often beautifully wrapped. The tradition of Oseibo is deeply rooted in Japanese culture and reflects the importance of maintaining relationships. It is similar to another custom called osechi, which involves special foods prepared for the New Year. Oseibo gifts are usually delivered in person or sent by mail, emphasizing the thoughtfulness behind the gesture.
