Kanji are logographic Chinese characters, historically adapted from Chinese writing scripts, used in the writing of Japanese. They comprised a major part of the Japanese writing system during the time
Nihon Shoki (720 CE), considered by historians and archaeologists as the most complete extant historical record of ancient Japan, was written entirely in kanji.
Furigana indicates the pronunciation above the kanji for the names of three stations on the Seibu Railway: 東伏見(ひがしふしみ) (Higashi-Fushimi), 武蔵関(むさしせき) (Musashi-Seki), and 西武柳沢(せいぶやぎさわ) (Seibu-Yagisawa). The sign also includes romaji below the kanji for each station.
