I'm getting in to Japanese stuff a bit more seriously and at the moment have aspitations of getting a full uniform together. I think it is affordable when you compare with other types of militaria and currently not as risky. On e-bay they go around the $100 mark, and if you do a 'Japanese Militaria' search quite a few dealers come up.
Lots of mint/unissued tunics on eBay. Finding a named issued tunic with period applied insignias is scarce!
Here are the pictures of the rank badge.
They are not sewn through the whole collar, just the first layer, but the start and finish knots do go all they way through. To me they look to be done by a competent sewer, it's very neat and uniform.
Good or bad I welcome your comments and appreciate you sharing your knowledge.
The color also came out a bit better on these photos.
