The Japanese crested ibis, also known as the "toki," is a critically endangered bird that is native to Japan and is considered a symbol of good luck.

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

The 16th century saw the rise of Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, who were instrumental in unifying Japan under a centralized government.
