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.

The flight
SQ618 · Business · Boeing 787-10 — nonstop SIN → KIX. Departs 01:25 Sat Sep 12, lands 08:50 (6h25). Check-in is at Changi Terminal 2 — SQ routes its Japan flights through T2, not T3. KIX arrivals come in at Terminal 1.
Check-in closes 00:45. SQ shuts the counters 40 min before departure and its gates close 20–30 min before — the counter is the real deadline, not the gate. Online check-in opens 48 h out (Sep 10, 01:25); do it and you only need the bag drop.
SilverKris Lounge, T2 Level 3 near Gates E — open 24 h. Business class gets you in, and that's where the two hours before a 01:25 boarding go. Eat in the lounge, sleep on the plane — you land and drive.
In the cabin bag: passport + IDP (the van won't move without it), van and hotel confirmations saved offline, ¥20–30k cash, eSIM installed and tested before you leave wifi.
Getting to Changi — MRT
East–West Line → Tanah Merah (EW4)↗ — transfer to the Changi Airport branch, ride to CG2 Changi Airport, then follow the linkways to T2. From the other side of town the Downtown Line to Expo (CG1/DT35) joins the same branch.
Last train to the airport: 23:50 (departures from Tanah Merah). A ~22:15 arrival leaves real margin; leaving after 23:00 is a gamble on the branch.
Grab / taxi is the no-timing-risk call — you're carrying a checked bag plus the camera kit, and the train drops you at CG2 with a walk to the T2 check-in row.
KIX → the van — the connection
Land 08:50 at T1 → immigration, then customs. Register on Visit Japan Web before you fly (account → passport → entry schedule → immigration + customs): one QR covers the immigration counter and the e-declaration terminal, and the paper forms disappear.
Taxi direct — the pick.↗ Stands are on the T1 arrivals floor (1F). Samurai Campers Osaka branch, 606-3 Oji, Kaizuka, is ~15 km / ~16 min over the access bridge. KIX's own fare table puts Izumisano at ~¥5,840 and Kishiwada at ~¥9,860, so budget ≈¥6,000–7,000 for Kaizuka. The 22:00–05:00 night surcharge doesn't apply at 09:00.
Rail alternative: Nankai Airport Express (空港急行) KIX → Kaizuka, 18 min / ¥600, then a 3.4 km / ~5 min taxi to the branch. Cheaper by ~¥5k, but it's a luggage transfer before 09:00.
Van handover ~09:30–10:00 (booking #DDDWNP) — then it's Day 1: Aeon Kaizuka for the stock-up, then the Hanwa Expressway south.
Metro & cards
ICOCA — JR ticket office (Midori-no-Madoguchi), T1 2nd floor, next to Kansai-Airport Station. ¥2,000 = ¥500 deposit + ¥1,500 usable balance. One card covers the whole trip: Osaka Metro, Nankai, Kintetsu, JR, buses, konbini.
Nothing on Day 0 needs the metro — the van is at Kaizuka and the next five days are driving. It comes back on Sep 17 (Kaizuka → Namba, Nankai Main Line ~32 min) for the Osaka leg.
Enjoy Eco Card (1-day unlimited Osaka Metro + city buses) — ¥820 weekdays, ¥620 weekends and public holidays, so Sep 19–20 come in on the cheap side. Only worth it on a heavy riding day; most of the Osaka plan is walked or on Kintetsu and Nankai.
Terminals
Changi T2 (SQ Japan check-in) → KIX T1 — arrivals and the van-side taxi rank both on T1's arrivals floor
Day 0 carries the only hard deadlines of the trip: counter 00:45, boarding ~00:40, wheels up 01:25. Be at Changi by ~22:30, live in the lounge for two hours, and the rest is downhill — through immigration by ~09:15, van keys before 10:00.
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
丹敷の湯 (Nishiki-no-yu spring)↗ — alkaline "beauty skin" bath at 道の駅なち, ¥600, 15:00–20:00. Closed Mondays, so on Day 3 go to ゆりの山温泉↗ instead — ¥400, 9:00–22:00, open Mondays (closed Tuesdays)
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, hard deadline. Leave ~07:00 → Kaizuka branch ~11:00–11:30 → van handed back with roughly five hours in hand. Samurai confirmed the return is strictly before 17:00, so treat 16:00 as the working target — worst case, the last departure from Ryujin Onsen is ~13:30 and from Koyasan ~14:15.
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.

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.

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.
