Spring Cleaning

Does not actually happen in the springtime for Japanese people.

It is something that everybody actually does before the new year, right around Christmastime, or soon afrer. The big osoji (cleaning). Everything must be cleaned. It is pretty much a ritual habit or culture aspect of Japan. Houses, work places, gardens. Everything. And not just your weekly cleaning. I am talking about spring cleaning clean, but almost over and beyond. At least over and beyond any spring cleaning I have ever done. Take everything out and individually clean it and clean the room. Ceilings too. Before you put anything back inside.
I even cleaned under my built-in bathtub with fungal cleaner.
They do this to welcome the new year with a nice and fresh house. The more and more I study about Japan and its culture it is so interesting how repetitive they are with all of their customs and reasons, it seems they are oddly superstitious. They always try to start everything, houses, relations, semesters  workplaces, anew as a way to purify it and to bring in good luck, longevity, and prosperity. To push out the demons of yesteryear and invite in the good spirits and freshness for the new year.
After everything has been cleaned, the decorations are put up, which often consist of mochi and oranges, as well as whatever the year's zodiac happens to be. Likely you will find those large bamboo pine decorations called kadomatsu in front of especially prestigious shops, hotels and other locations soon after as well. In homes, a bit more modest decorations are in place, in addition to their mochi and oranges, they also will typically have  twists of straw rope they are a bit famous for, as well as their paper decorations. All of these things will again reinforce the themes of purity and prosperity in their homes and workplaces.
