大和 (Yamato) is the classical name for Japan's heartland - originally a province around modern Nara. The Japanese themselves sometimes still use
大和 for poetic 'Japan-ness'. The WWII battleship
大和 (Yamato) - the heaviest battleship ever built - was named after this province. Note the unique Japanese reading: characters read as 'da-he' in Mandarin but 'yamato' in Japanese.
