2 to 3 snips of (copper) magnet wire (12 or 13ga), then glued together, make a good Longhorn, too. 2 is about right...3 is a bit heavy to balance on most arms.
Any non-magnetic metal cut into 1.5" strip that will fit on the front of your cartridge either by solder or tacky clay will do the job, too.
Magnet wire should be easily found in Japan, I'd think
