Overview

The practice of thorough cleaning, typically done at the end of the year. It represents both physical cleaning and spiritual renewal.

History and Cultural Context

Osoji, meaning big cleaning, is a deepcleaning tradition in Japan rooted in Buddhist and Shinto beliefs about purification. Dating back centuries, it is most famously practiced at the end of the year as Ōsōji, when families, schools, and businesses thoroughly clean their spaces to remove physical and spiritual impurities before welcoming the new year.

The practice is about more than tidying—it symbolizes a fresh start, clearing away negativity, and creating a harmonious environment. Osoji is also seen in daily habits like removing shoes before entering a home and maintaining clutterfree spaces, reflecting Japans deep cultural respect for order and simplicity.

Modern Applications

Today, Osoji is embraced not just as an annual tradition but as a mindful approach to everyday life. Inspired by minimalism and the Marie Kondo method, many people worldwide now use Osoji principles to declutter their homes, improve focus, and reduce stress.

Businesses and schools continue to incorporate group cleaning sessions, fostering teamwork and responsibility. Beyond physical spaces, Osoji can also be applied mentally—letting go of unnecessary worries and distractions to create a clear and peaceful mindset.
