Above the entrance door you will see a shimekazari, a braided rice straw rope whose simplest symbol means stopping the bad spirits. A more complex shimekazari, like the one photographed here, also includes auspicious objects such a crane (tsuru) made of Mizuhiki cord, which is a symbol of longevity. An even more interesting auspicious object is the daidai Japanese bitter orange, a symbol of family continuity because daidai, usually written 橙, can be written with a different kanji, 代々, which means "from generation to generation".
