Japanese New Year Decorations Explained: A Complete Guide to Kadomatsu, Shimenawa, Kagami Mochi, and More

If you visit Japan during late December or early January, you’ll notice something special the moment you step outside.

Entrances of houses, shops, and even offices are decorated with bamboo, pine, straw ropes, and beautifully arranged ornaments.

These are Japanese New Year decorations, and they are much more than seasonal decorations. Each item carries a deep meaning connected to wishes for health, happiness, and good fortune in the coming year.

In this guide, I’ll walk you through the most important New Year decorations in Japan—what they are, what they mean, and where you can see them—in a simple, traveler-friendly way.

This is part of TossysGuideJP, where I explain Japanese culture in a way that actually makes sense when you’re visiting Japan.

Why Do Japanese People Decorate Their Homes for New Year?

New Year, or Oshōgatsu (お正月), is the most important holiday in Japan.

Traditionally, it’s believed that a special deity called Toshigami-sama visits homes at the beginning of the year to bring good luck, prosperity, and protection.

New Year decorations are prepared to:

Welcome this deity Purify the space Express hopes for the year ahead

Most decorations are put up between December 26 and 28, and removed around January 7.

Now, let’s look at each decoration one by one.

What is Kadomatsu?

Kadomatsu is a decoration made of:

Bamboo Pine branches Sometimes plum branches

It is usually placed at the entrance of a house, store, or building.

Meaning Behind Kadomatsu

Kadomatsu literally means “gate pine.”

It acts as a marker and resting place for Toshigami-sama.

Each element has meaning:
