Overview
Manju (万寿) is the Japanese era name (nengō) that spanned from July 1024 through July 1028. Era names are regnal or calendar markers used in Japan to group years; the characters 万寿 are commonly rendered as a wish for long life or enduring felicity. The Manju era sits in the middle of the Heian period and is bracketed by Jian before it and Chōgen after it.
Context and political setting
The reigning sovereign during Manju was Emperor Go-Ichijō. Like other early eleventh-century reigns, the court operated under the cultural and political norms of the Heian aristocracy, where influential families—most notably branches of the Fujiwara—exercised considerable power through regency and marriage alliances. Era names were changed for a variety of reasons: to mark auspicious occurrences, respond to disasters, or formalize a new phase of rule.
Characteristics and chronology
- Start and end: July 1024 – July 1028.
- Emperor: Go-Ichijō (reigning during the era).

Culture and significance
Although Manju itself is a relatively brief and administratively quiet span, it forms part of the continuity of Heian court culture. Poetry, court rituals, and the patronage of Buddhist institutions remained central to elite life. Historical interest in short eras like Manju comes from their role in dating documents, court diaries, and temple records—primary sources historians use to reconstruct political, religious, and cultural developments of the period.
Notes and usage
When consulting historical materials, Manju is used as a chronological label rather than a programmatic policy name. For more detailed chronological tables or contemporary records, specialized histories and collections of court diaries and temple chronicles should be consulted; these are typically indexed under the Manju years in Japanese primary-source catalogues.
