Tokyo to Kansai Rail Adventure

I've put together a classic "Golden Route" itinerary for you! Since you specifically mentioned the Shinkansen (bullet train), we’ll skip the car rentals and use Japan's amazing rail network to zip between cities. I've stretched this to 7 days as requested to keep the pace brisk but manageable. Seven days of neon lights, ancient shrines, and the best street food in the world via high-speed rail.
