While this shamisen was previously built by an unknown maker in Japan (sadly, there are almost never signatures nor identification marks from shamisen makers), my guess is it was made in the 1990s to early 2000s. There is a moderate amount of tochi (figure) in the kouki sao, but has beautiful deep red throughout. This instrument has been fully refreshed to brand new condition by the legendary craftsmen at Tokyo Wagakki, which includes their signature mirror-like polishing technique. This shamisen can be skinned with the brand new Hibiki Sonic synthetic skin (not yet publicly available).
Note: The deep vivid reds in the kouki is more striking in darker rooms with direct light. I've included a few photos of the tenjin in a regular room so you can see it's darker appearance with ambient lighting.

As you can see in the photo, the left Eclipse has a redder hue than the right Eclipse. There is no difference in quality nor tone, but it's simply the natural color of the polished wood. As stated above, the Eclipse uses no stain or lacquers, so please know that any particular Eclipse shamisen might be redder or tanner than another.
