Order of the Rising Sun

The classes were abolished in 2003, so all decorations from 2004 had a name attached. Here are the current names.

Grand Cordon of the Order of the Rising Sun  (previously the 1st Class decoration)
The Order of the Rising Sun, Gold and Silver Star (previously the 2nd Class decoration)
The Order of the Rising Sun, Gold Rays with Neck Ribbon (previously the 3rd Class decoration)
The Order of the Rising Sun, Gold Rays (previously the 4th Class decoration)
The Order of the Rising Sun, Gold and Silver Rays (previously the 5th Class decoration)
The Order of the Rising Sun, Silver Rays (previously the 6th Class decoration)

The 7th and 8th classes were abolished. You can see pictures of the current designs
HERE.
Order of the Rising Sun Gold Rays Medal. This is the new revised medal design that was
implemented in 2003. This corresponds to the old 4th Class medal. Note that the reverse
has no enamel. This is the way the post-2003 medals are being made.

HERE for the official Decorations Bureau photos.

For those interested, 'C7' is stamped on the reverse.
