Amex Biz Gold in US, benefits in Japan?

I'm considering applying for the Amex Business Gold from the US. I know it will be easier for me to get there than the runaround that I might expect if applying in Japan with my company.

My question is – the benefits of the Amex Biz Gold card in the US normally doesnt have Airport lounge access. But in some markets like Canada, UK it does. And in Japan on the application page it says Lounge access at domestic airports so must include NRT/HND. Will my US Amex Biz Gold card get me into the Japan lounges?

There are also some local benefits that would be interesting like baggage delivery.

Oddly US welcome offer is 100k, Japan is 150k + opptys for +100k.
