In Japan, there are many traditions, so I'll only name a few.
1. Daruma Doll
The Daruma Doll is a Japanese tumbler doll (ever heard of Weeble Wobbles?) that is made out of paper mache and is modeled after Bodhidarma, a Buddhist monk, who wanted to reach enlightenment. To achieve that, he sat in a cave for 7-9 years (exact years are unknown) in meditation. After acheiving enlightenment, he lost the use of his arms and legs, and rolled around to spread his teachings.
Daruma Dolls are weighted at the bottom, and won't fall down. This stands for perseverance, dauntless courage, and final success.
Daruma Dolls don't come with pupils in their eyes. You make a wish or a goal, then fill in it's left eye, which would be the right eye from where you're looking. When that wish or goal is fulfilled, you fill in the other eye. In Japan, at the end of the year, all Daruma dolls are brought to a temple to be thrown in a bonfire. Then, at the beginning of the year, you get a new one. They are supposed to be good luck charms.
There are 3 kinds of Daruma Dolls that I know of: a man with a grumpy expression, pretty ladies, and Daruma Dolls for kids, for which the most common ones have black bangs, and red with white faces.
2. Kimonos Kimonos are the traditional wear for women and girls. They are only worn on special occasions, and there are different types of kimonos for different seasons.
3. Maneki Neko
Maneki Neko (literally "beckoning cat") is a good luck cat. It is placed in the northeast corner of the house to keep them happy. They are ceramic, and are sometimes used as a piggy bank. This cat, like many other things, comes with a story: "A young woman had a cat, which she valued above all else. One day, she had her friend, a swordsman over. The cat suddenly went frantic, clawing at the woman's kimono. Thinking the cat was attacking her, the swordsman severed the head of the cat, which flew through the air, then lodged its teeth into a highly poisonous snake on the support boards above. After the incident, the woman would neither eat nor sleep. The swordsman felt guilty for what he had done and sad for the woman. He went to a woodcarver, who was called "the best in the land", who made him a carving of the cat, a paw raised in greeting. When he gave the carving to her, she was overjoyed and lived her life again instead of suffering."- Wikipedia
