It's a GZ73/NL-NRA https://dynabook.com/direct/onyx-blue-pgz73nl-nra.html Actually, I was mistaken. It's 859 grams :-) That includes the battery. This particular model has only a 256 gig drive on it, though. I should also point out that it's an Intel box. I'm impatiently waiting for an AMD box with similar battery performance.
I don't understand why they don't sell it elsewhere. It was the same with the previous model I bought. You've got a full power, A4 sized, < 1kg laptop that gives you a full day's work on a charge. How can they not sell that? And eventually Toshiba decided they had to exit the laptop market because they couldn't make any money at it... It's baffling.
That's not actually the same machine. There is a similar model on the Japanese side. It's missing some extra USB-A connectors and an actual network connector. I think the extra weight is actually because battery technology is different. It is possible that they can't sell the lighter / longer life battery in the US. But, you are right anyway. It's close enough :-) I'm glad they are finally realising that this is a useful configuration for some people.
it's rare enough to find an i7-8th gen in anything without a >=15" screen and keyboard with numpad. Dell Ultrabooks perhaps but they start at 1.2kg AFAICS
