I'm not much of a Yamaha guy. Can anyone identify this bass?

An open wrapped 620G?

Looks like a YBL-612 to me. The model number is usually on the cork barrel (mouthpiece receiver side).

It doesn't seem to be a 612 - missing the gussets on the slide braces. This is the best image I have of the top cork barrel.

The open wrap and extended 2nd valve (custom) 620 looks close- this pic is a Yamaha pic

So the best guess is that it's a custom wrap?

It isn't a 612.
The second photo shows one. It would take a LOT of work to get from stock to the one posted by the OP.
First photo is a 620G. Pretty easy to get from one to the other.

The D slide is a standard option for the second valve. The stock Yamaha photo shows the Eb slide in place.

Ok, yeah, I see it. So a 620 with a custom opened F side and optional D extender. Below is a pic from Brass Exchange of a 620 with the D extension, and stock F side. Looks similar, right down to the braces and brass/nickel pattern.
Thanks.

It looks a lot like a 620 that C Murray was selling about a year ago. It had a open wrap F att.
The 612 had a 10” bell and string linkage.

Note that it has one of the "fancy" F-attachment paddles that they put on their top tier lines. Also looks to have a removable leadpipe. I mean, they could have modded a 620G, but the changes in the blow and such would be negligible, IMHO. Also they would need to get another of those S bend tubes. It looks very well done with the correct Yamaha hardware.
Most likely, this is a non U.S. Market Bass Trombone, probably a Japanese only custom model.

It would be a very easy job for the factory to do this wrap on an existing chassis, such as that of the 620G. I expect you're right about a Japan only product.

It looks nice, but - honestly - there is nothing wrong with the 620's usual F wrap. I guess there is no slide dumping on this one.

Doesn’t Yamaha describe the standard 620G wrap as ‘semi-open’?

It's a redistribution of exactly as many curves, and of comparable radius, as the traditional closed wrap arrangement. (Arguably/theoretically marginally 'worse' because of the tight 180 through the valve ports, rather than a wider 90 bend followed by a 90 port.)
Does this matter? Not at all. Nothing wrong with a closed wrap, and Yamaha makes good valves.
But 'semi-open' is marketing nonsense.
