The Japanese spider crab is the largest arthropod in the world, with a leg span of up to 4 meters (13 feet).

The Japanese language is written using three scripts: kanji (Chinese characters), hiragana, and katakana (both phonetic scripts).

The first novel ever written, The Tale of Genji, was written in Japan in the 11th century by a noblewoman named Murasaki Shikibu.
