Quick Trip

Hi There, we are doing a reasonable short trip to Japan but wanting to full our days up the best we can. We are looking at the following itinerary. Would you suggest the 7 day pass to get us from Tokyo-Kyoto-Hiroshima-Kyoto-Osaka then back to Tokyo in those 7 days, or use a local regional pass.
Not activiating the pass until we leave Tokyo and use individual train passes when arrive back in Tokyo?

Many Thanks
Victoria
