Half a Confession (半落ち, Han'ochi) is a 2004 Japanese film directed by Kiyoshi Sasabe.

[2] Respected inspector Soichiro Kaji is imprisoned for killing his wife, Keiko, who, suffering from Alzheimer's disease, requested it.

His colleagues at Tokyo Police Force discover that Kaji intended to commit suicide after killing her, but instead went away on a bullet train two days later.

A suspicious item is found in his coat pocket that suggests Kaji was unfaithful.

The incident makes headlines in Tokyo, where a young female reporter sets out to find the truth about the acclaimed yet intriguingly silent defendant.
