Japanese Red Cross was founded June 1888. Regular membership Medal - for members who have contributed more than 300 yen. initially struck in silver, then aluminum.Special member Silver Medal - for long-term contributors.Special gold membership medal - for members who have contributed more than 10,000 yen.
Medals of merit Japanese Red Cross granted to foreigners who have become contributing members of the Japanese Red Cross.
Originally only one class in silver from 1956 in two classes of silver (greater contribution 50,000 yen) and gold (by more 100,000 yen).
The one on Your picture is Medal of merit Japanese Red Cross, and the ribbon or suspension is missing it could be part of the Japanese Red Cross in time of war-Japan- Russia in 1904-1905. and then the medal is worn on the ribbon prescribed, which is valid for all the decorations , it is also known to wear a simple metal clip or sling is made a symbol of the Red Cross - quite rare. The second option is small metal bar.
In any case in my opinion the suspension on Your medal is not regular and probably made buy the owner of the medal because he lost the original ribbon or suspension.
I am sorry I do not know hoe to put the photos to show the examples on the message I will try to learn that quick.
CHEERS
