The afternoon itinerary is rather packed, and there may not be enough time for travel and sightseeing. We suggest adjusting Miyajima to a separate day for your visit. This would allow for more leisurely worship and exploration, improve the overall quality and comfort of your trip, and leave room for flexible rest, making your itinerary smoother and more worry-free. Thank you.
