Year-End Cleaning(年末の大掃除)

WORK’IN JAPAN

31.01.2026

Did you clean your home at the end of the year? In Japan, we have a custom called osoji (big cleaning) before the New Year begins. This doesn’t just happen at home or school; it’s a common practice in the workplace as well. Today, I’d like to share why we do this, what it involves, and my own personal experiences.

Why Do We Do the Big Cleaning?

As a Japanese person, I’ve been doing osoji at home and school since I was a child, so I never really stopped to think about “why” we do it.
When I looked into its origins, I found that it dates back to a Heian Period (794–1185) court ritual called susuharai (soot sweeping). The tradition began as a way to sweep away the dirt accumulated over the past year, purifying the space to welcome the Toshigami-sama (New Year deities) who bring happiness for the coming year.

What Kind of Cleaning Do We Do?

While many companies hire professional cleaners for their daily upkeep, it is common for employees to take the time to clean their own desks, shared storage rooms, and the office kitchenette themselves. We even tackle things like dusting around electrical wiring and cables. On the other hand, many companies also take this opportunity to bring in specialists to handle more technical tasks, such as deep-cleaning air conditioner filters.

My Experience

In my previous workplace, I spent osoji disposing of expired documents and organizing my desk and the storage area. By cleaning the tools and spaces I use every day, I felt a sense of gratitude toward them and a renewed desire to take good care of them. I believe that by decluttering our physical environment, we also organize our minds, allowing us to welcome the New Year with a fresh perspective.

When Do You Do Your “Big Cleaning”?

Is there a similar culture of year-end cleaning in your country? I believe osoji is a wonderful tradition that allows us to reflect on the past and move forward with a clear mind. Even though 2026 has already begun, I hope this spirit stays with us throughout the year. I hope your 2026 will be a fulfilling and wonderful one.
