Chōhō (era)

Chōhō (長保) was a Japanese era name (年号, nengō, literally "year name") after Shōryaku and before Kankō. This period spanned from December 10, 999 to January 16, 1004. The reigning emperor was Emperor Ichijō (一条天皇).

The era's name was derived from a statement in the I-ching (Book of Changes): "The preservation and maintenance of correctness lead to auspiciousness and longevity."

Significant events during the Chōhō era include:

• Chōhō 3 (1001): Fujiwara no Teishi, consort of Emperor Ichijō, died.
• Chōhō 5 (1003): Construction of the Chōhō-ji temple was completed.

The era coincided with the continued influence of the Fujiwara clan during the Heian period. Fujiwara no Michinaga held considerable power as regent (sesshō) during this time.
