Osoji: The Year-End Deep Cleaning Tradition to Welcome the New Year
In the West, many people embrace “spring cleaning” as a chance to refresh their homes when the weather warms up. Dusting, sweeping, wiping, and scrubbing—it’s a way to welcome new energy into the space after winter.
In Japan, we have a similar tradition, but it happens in December, just before we welcome the new year. This practice, known as Osoji (大掃除), translates to “big cleaning,” and it holds deep cultural and spiritual significance.
Osoji is more than tidying up—it’s a ritual of purification. According to Shinto beliefs, the New Year deity, Toshigami (年神), visits each home to bring health and good fortune to families. Before Toshigami can enter, the house must be cleansed of dust, clutter, and impurities. Once the home is spotless, the front door is adorned with a traditional shimekazari (rice straw rope decoration). This decoration serves as a symbol of welcome, ensuring the family and home are ready for Toshigami’s arrival.
Osoji is a family event where everyone pitches in. From grandparents to teenagers and even small children, each member plays a role in preparing the home for the new year. As a child, I loved this tradition—it was a time to connect with my parents and grandparents. Cleaning and putting up the shoji screens was my favorite part. It felt so rewarding to see our home transform as we worked together.
This tradition dates back to the Edo period, when households began cleaning in the second week of December. Today, with our busy lifestyles, many start much later in the month, but the cleaning must be completed by December 31st at midnight to fully welcome the new year.
Osoji isn’t just for families. Many Japanese businesses and workplaces also participate, giving offices a thorough cleaning before closing for the holiday. It’s a communal effort, with everyone contributing to make the space fresh and ready for a new start.
Beyond the physical act of cleaning, Osoji is a ritual to cleanse the soul and spirit. By removing dust, clutter, and negative energy, we create space for renewal, positivity, and opportunity in the year ahead. It’s a tradition that feels deeply satisfying and meaningful.
I hope this beautiful Japanese custom inspires you to try Osoji this year. Whether it’s a deep clean of your home or simply clearing a small space, it’s a wonderful way to start the new year with a clear mind and a fresh outlook.
