Translation guide
In Japanese, referring to a former emperor depends on context, era, and formality. The most common modern term is 上皇 (jōkō), used for an emperor who has abdicated. Historical terms like 太上天皇 (daijō tennō) and 院 (in) are used for pre-modern abdicated emperors. In casual or media contexts, 元天皇 (moto tennō) may appear, but it is less formal.
Referring to a living former emperor who has abdicated, especially in contemporary Japan (e.g., Emperor Emeritus Akihito).
Standard term for a living former emperor who has abdicated. Used in official and media contexts. Often combined with 陛下 (heika) for respect: 上皇陛下 (jōkō heika).
上皇陛下は静かな生活を送られています。
His Majesty the Emperor Emeritus leads a quiet life.
Formal historical title for an abdicated emperor. Still used in official historical contexts, but 上皇 is more common in modern usage.
太上天皇は平安時代に多く見られました。
The title Daijō Tennō was common in the Heian period.
Literally 'former emperor'. Used in casual or journalistic contexts, but can sound blunt or disrespectful. Not used in formal address.
Avoid using 元天皇 in formal or respectful contexts; prefer 上皇.
元天皇が公の場に姿を見せた。
The former emperor appeared in public.
Referring to an emperor who abdicated in pre-modern times, often entering religious life.
Title for a retired emperor, especially after taking Buddhist vows. Often used with a specific era name, e.g., 白河院 (Shirakawa-in).
白河院は院政を始めた。
The Retired Emperor Shirakawa began cloistered rule.
Also used historically for abdicated emperors, but 院 is more specific to the cloistered emperor system.
Referring to an emperor who has passed away, often in historical or respectful contexts.
Refers to a deceased previous emperor, often in historical narratives. Implies respect.
先帝の遺志を継ぐ。
To carry on the will of the late emperor.
Literally 'the late emperor'. Used in formal announcements or obituaries.
故天皇の葬儀が執り行われた。

上皇 is the modern standard term for a living abdicated emperor. 太上天皇 is the formal historical title, now largely replaced by 上皇 in everyday use. 院 specifically refers to a retired emperor who became a Buddhist monk or exercised cloistered rule, common in the Heian and Kamakura periods.
Do not use 前天皇 (mae tennō) or 旧天皇 (kyū tennō) to mean 'former emperor'; these are not natural Japanese. 元天皇 is possible but can sound disrespectful. Stick to 上皇 for modern contexts.
多くの上皇が院政を行った。
Many retired emperors exercised cloistered rule.
