Does the ac adapter work in japan (100v)?

AC adapter works with 100v, grounded outlet.

Can you connect another usb hub to the usb ports?

Your question probably could be simply answered yes. But the real answer is why and what will happen. You plug this into a single 3.0/1 USB port to connect to the computer. It can only pass so much data and it cannot double that data or anything else. So attaching another Sipolar hub might work, but you will not get the result you expect. Better to plug it into ANOTHER 3.0/1 USB on the computer. Daisy chaining them really is not a great idea at all. Not even for charging lots of mobile phones are other computer batteries. But on their own USB ports on the computer will give you what you want, I think. Somewhere in my foggy memory I think most computers can support 20 usb ports without a problem. However, once again, remember that each port on its own only supports so much. If you are trying to put a bunch of ASIC USB miners together, it might just work on a daisy chain. But you also have to remember power. The unit is 12v 10 amp, and if you are pushing those miners you will have to give them more power. I think they want 2.5amp so you need to get a more powerful power supply to jam 10 in each one. Hope that helped.
