Since it's a single PNR and you're in biz, I'm sure they'll try, but no guarantees that you can make it. This may also depend on why you're late and just how late you are.
All that said, KIX-HND-NRT-somewhere sounds like a deeply sub-optimal way to get anywhere. Are you sure you can't fly directly out of KIX, out of HND, ITM-NRT, anything...? (I was going to suggest KIX-NRT, but apparently only LCCs fly that anymore.)
Many thanks! ^I did this cx once, but can't remember how long it took me.... I agree it's not optimal, but it's what was available when I booked it (it's an award ticket, and I really wanted to fly ANA and avoid UA or AC...)
