Japanese have their own version of Diwali cleaning; here’s what it is called

If you’re still feeling like your year did not begin on the right note and want a fresh start, embrace the power of Oosouji and give your home—and your life—a meaningful reset.

What is Oosouji?

Oosouji, which translates to “big cleanup,” is an annual deep-cleaning tradition in Japan, typically performed at the end of December before the New Year (Shōgatsu).

Families, schools, and businesses participate in this ritual, ensuring their spaces are spotless before the new year begins. This practice is not just about physical cleanliness but also about mental clarity—letting go of unnecessary clutter, both tangible and emotional.

How it helps:

Decluttering for Mental Peace – Studies have shown that a clean, organized environment reduces stress and boosts productivity. Oosouji promotes minimalism, helping you detox your space for a clearer mind.

Welcoming Positivity and Good Fortune – Similar to Diwali cleaning, Oosouji is believed to remove negative energy and invite good luck for the new year. Many Japanese people follow the Feng Shui principle to harmonise their living spaces.

A Fresh Start for the New Year – By eliminating unnecessary items, you create space for new opportunities. Oosouji encourages people to let go of emotional baggage, making way for fresh beginnings.

Boosting Productivity and Efficiency – Japanese businesses practice Oosouji to create a more organised and efficient workspace. A clutter-free environment enhances focus and workflow, leading to better productivity.

Improved Hygiene and Well-being – Deep cleaning helps eliminate dust, mold, and allergens, leading to better indoor air quality and overall well-being. With rising pollution levels and indoor allergens, this practice is more relevant than ever.

How to perform Oosouji at home

• Start with Decluttering: Sort through items and discard things that no longer serve a purpose. Follow the KonMari method by Marie Kondo—keep only what “sparks joy.”
• Deep Clean Every Corner: Move furniture, wipe down surfaces, clean windows, and focus on neglected areas like storerooms and attics.
• Organise and Simplify: Use innovative storage solutions to maintain order in your space.
• Purify with Natural Elements: Many Japanese households use salt or incense to cleanse their homes spiritually.
• Reflect and Set Intentions: Just like in Japanese tradition, take time to reflect on the past year and set positive intentions for the new one.
