Hiroshima is Day 10 on many 10-day Japan trips. Pad it or the museum becomes a blur.
Day trip from Osaka
07:00 Shinkansen, museum at opening, park, ferry, last sensible train back. Check tide and last ferry. Brittle but common.
Overnight: museum and island
Afternoon museum and park, morning Miyajima at the tide you chose. This is the version that belongs on 14 days.
On the 10-day circuit
Osaka 2 nights, then Hiroshima as the last full day before a flight from KIX or a return to Tokyo. Do not add Kanazawa on the same day.
