Not your average samurai movie!, 13 February 2013
Author: Dirk Angel from United Kingdom/Australia

If you like lots of violence and swordplay, then this is not the film for you. This is a gentle, often humorous film about a go master with an interest in astronomy and mathematics who is appointed to revise the Japanese calendar. At the time, Japan used three different calendars, none of which were accurate. This is the tale of his efforts to create an accurate calendar that predicted eclipses, the seasons and other events of importance to everyday life, and his efforts to persuade the Emperor to accept his revisions and adopt the new system. There is also a gentle sub- plot of his relationship with the woman that was to become his wife. An utterly absorbing and entrancing movie!
