Kanji for Emperor
The kanji most commonly used for "Emperor" are 帝、皇.
帝
Kanji that mean Emperor
帝 (tei / mikado) is the emperor as supreme sovereign. In ancient China it named the divine ruler — 上帝, the Lord on High — and history kept it for emperors of every land: ローマ帝国, the Roman Empire; 帝政, imperial rule. Japan’s classical court called its own sovereign the mikado, written with this character.
皇 (kō / ō) is the specifically imperial character of Japan’s throne: 天皇 (tennō, the Emperor of Japan — “heavenly sovereign”), 皇室 (the imperial family), 皇居 (the palace grounds in central Tokyo). It stacks 白 on 王 — a radiant king. The two characters meet in 皇帝 (kōtei), the word for foreign emperors from Rome to China.
The supporting court: 陛 in 陛下 (His/Her Majesty — literally “beneath the palace steps”, where petitioners stood), 后 (empress), 朝 (the court and its era), and 帝都, the imperial capital — old Tokyo’s grandest name.

Before you use Emperor kanji
帝 reads as "emperor" with continental, historical weight — commanding but not tied to any one throne. 皇 alone reads specifically as Japan's imperial line, which is a statement to make deliberately. 皇帝 in full is the unambiguous word. All are formal characters; none has a hidden negative, only gravity.
