It is a Japanese New Year custom to display, on the house entry door or on the porch, a special knitted rope made from rice straws called shimekezari. Special strips of zigzag folded white paper, called shide, are hung on rice rope, the result being one of the best-known Japanese decorations:

Shimenawa is usually used at Shinto shrines to mark sacred spaces and to chase away the evil spirits. The shimekezari used on New Year has a similar meaning.
There are more methods to make a shimenawa and also several methods to make a shide, which can have 2, 4 or 8 folds.
If you wish to see how it is made, here are two excellent videos detailing the procedures:

Another New Year Japanese custom is to place, on both sides of the entry door, kadomatsu (門松, meaning gate pine), a decoration made from bamboo, pine or ume twigs, tied together with a straw rope.
Each element from the kadomatsu carries a significance, the bamboo symbolizes strength and growth, and the pine symbolizes long life. Usually the kadomatsu is made from 3 bamboo strains, diagonally cut, around 1 meter tall.

The kadomatsu, considered temporary housing for kami (gods), are placed on the front door after Christmas and are kept until January 7th, to welcome the toshigami, the god of the new year.
It is believed that toshigami brings prosperity and good luck in the next year to the families (or the businesses) protected by kadomatsu.
Here are several photos with various kadomatsu:
