While I imagine some of the Australian members have seen these, I'm sure the other members might enjoy Lieutenant General Imamura and Baba's swords.   General Imamuras sword was a gift from the Emperor in 1918 and is thought to have been made by Kanenori Miyamoto or Gassan Sadakatsu.    Another interesting sword is a Kai Gunto of Lieutenant Kenshi Chuma, recovered from the midget sub that attacked Sydney harbour.   Detailed info on the Kai Gunto: https://www.awm.gov.au/collection/C20
