He'll be on Continental flights 008 from NRT to EWR and then flight 0753 from EWR to CMH.
If you go to the below website while he is in flight you should be able to select the airline and choose the flight number and watch a realtime animation of his flights Make sure you select "graphical version" though or you will just get text.
