Days 1–4 are fixed: Osaka → Shirahama → Kushimoto → Nachi → Hongu. Night 5 is the onsen choice — the beauty bath at Ryujin Onsen (locked) or the michi-no-eki at Okutoro (alternative). Same Day 5 gorge, same relaxed Day 6; the difference is the soak and the Skyline.
Most exposed stop on the route. Cape Shionomisaki is literally used as a reference point when tracking typhoon positions relative to Japan. If a storm is tracking in during your window, this is the day to compress or skip first.

Drive~30km totalshorthops24 min + 10–15 min legs
To see
Taiji↗ — historic whaling port, now a base for whale & dolphin-watching boats
Deliberately the slow day of the trip — the road follows the river and gets genuinely narrow near Yunomine, with many blind corners. Budget the full hour, don't stack much else on top.
Dorokyo Gorge↗ — river boat tour ¥3,000 (40 min, departures 9:00–15:00, closed Mondays, pay cash/PayPay on the day)
Log rafting↗ — runs daily except Thursdays through Sep 30, departs right from the michi-no-eki
Ryujin Onsen Motoyu↗ — one of Japan's three beauty baths: silky sodium-bicarbonate water, ~1,300 years old. Evening soak after the gorge — the whole point of the detour.
Ryujin village lot↗ — public lot near the Mandarya Museum, ~2-min walk to the bath. NOT 道の駅 龍神 (24/7 lights, highway noise)
Caution
Rain risk, not wind risk. The mountain roads' real hazard in bad weather is landslide/rockfall, not the storm itself — R371 has a history of closures. If heavy rain is forecast, this is the day to swap out — not push through.
Alternative — keep it in your back pocket: skip the Ryujin leg and sleep at Michi-no-Eki Okutoro (24h toilet, onsite onsen ¥700, car-sleep OK) — the original plan. Costs the beauty bath and the Skyline morning, saves ~50 min of driving, and it's the call if the Sep 16 forecast is wet.
The Skyline morning. The Koya-Ryujin Skyline (42.7 km, R371) climbs over Mt. Gomadan (1,277 m) — the trip's last great drive, same corridor as Day 1 in reverse. View stop: 道の駅 ごまさんスカイタワー on the ridge.
Easy timing. Leave ~07:00 → Kaizuka branch ~11:00–11:30 → van back before midday. No 23:00 heroics.
Train to the hotel: Kaizuka → Namba on the Nankai Main Line, ~32 min. Bag drop by ~13:00, afternoon free — BOOKOFF PLUS Namba is 2 min from the hotel if the used-goods itch starts early.
The Skyline closes in high-wind warnings — if Sep 17 has a wind advisory, drop to the lower Gojo corridor (R168) and it's still a relaxed morning. Weather pushing something back earlier in the week still gets absorbed here, just with an earlier alarm. Storm-morning fallback: if the Sep 17 forecast is bad (mountain rain), decide the night before — drive ~1h40 to 道の駅 紀の川万葉の里 on the 16th evening, sleep there, and the 17th becomes a ~1h05 hop to the branch. Costs the Ryujin night; only pull it when the forecast says so.

Osaka used-goods crawl — games & electronics
Lines2Kintetsu~30min eachNara + Osaka lines from Namba / Tsuruhashi
Stops (in order — books skipped)
Hard Off 東大阪若江店↗ — Kintetsu Nara line to 八戸ノ里, 16 min walk. 10:30–19:30. Audio, cameras, instruments, game consoles, junk corner. The whole reason for the day — start here.
BOOKOFF SUPER BAZAAR 25号八尾永畑店↗ — Kintetsu Osaka line to Yao. Games, retro consoles, hobby, electronics — skip the book aisles, this is the second haul. Budget 2 hours.
BOOKOFF PLUS なんば戎橋店↗ — optional evening closer, 2 min from the hotel: games, cards, hobby. Only if the bags aren't full.
Stock turns over daily — treat it as a hunt, not a shopping list. If the electronics itch isn't scratched, Hard Off 大阪湯里店↗ (south Osaka, grand-opened Aug 28 — address pin: 照ケ丘矢田 2-23-1). Two big stores in a day is plenty — don't stack three.

Osaka — no plan wander day
ModeWalk+ metro¥0planNamba / Dotonbori / wherever the day goes
The day
Wander. Hiroshima dropped (2026-09-04) — this is the decompress day before flying home. No stops planned on purpose. If a photo window opens: Shinsekai at dusk, Dotonbori neon, Hozenji Yokocho early evening.
Yakiniku Kitan Hozenji↗ — the one fixed point: dinner ~19:30 on Hozenji Yokocho (booking moved from Sep 17; book on Tabelog — search 焼肉 きたん 法善寺).
The 19th used to be a hard Hiroshima day — now it's the opposite on purpose: nothing stacked, flight is tomorrow. Let the camera and the stomach lead.

Osaka → KIX → home SQ621 · 17:25
Rail34min~¥1,670Rapi:tNankai Namba → KIX · or 45 min / ¥970 Airport Express
Flight-day math
SQ621 departs 17:25 — 3h buffer = at KIX by 14:25, 2h = 15:25. Trains run every 15–30 min, so the only real decision is when you leave the hotel.
Latest comfortable departure: Namba platform 13:30 → KIX 14:05, ~3h20 of slack. Sunday + festival crowds + check-in lines — don't go tighter.
Hotel checkout is 10:00 — bags at the front desk or Namba coin lockers, then you've got 10:00–13:15 free.
Festival morning still fits: Kishiwada is en route — Namba → Kishiwada ~25 min, Kishiwada → KIX ~20 min. Do the festival till ~12:45, train straight to the airport. Bags stay at the hotel in Namba, pick them up on the way through only if you route back — otherwise keep them stored.
If you skip the festival: checkout 10:00 → BOOKOFF PLUS Namba (opens 10:00) till ~11:30 → lunch → platform 13:30. Either way, KIX by ~14:05 and the trip is done on time instead of on adrenaline.
