Hotels With Free Parking Near Oiso
Driving is the practical way to see this stretch of the Sagami Bay coast — trains link the main stations but the onsen valleys and quieter beach roads sit well outside walking distance — so free parking narrows the list fast. Only two hotels near Oiso Long Beach include it outright: Hadano Yugawara Onsen Manyo-no-Yu, a riverfront hot-spring hotel in the hills behind Hadano, and Tsurumaki Onsen Jinya, a refined hot-spring inn further along the valley. Both trade beach proximity for a genuine onsen setting, and both throw in a free transfer service on top of the parking, useful once the car is left for the evening in favour of the bathhouse.
The hills behind Hadano and Tsurumaki carry a different character from the Oiso coastline: fewer day-trippers, a slower onsen-town pace, and a road network built around driving rather than the JR Tokaido Line that serves the coast. Both hotels in this group lean into that setting with a free transfer service alongside the parking, acknowledging that most guests arrive by car and may not want to drive again once they've settled into the bathhouse for the evening.

Where to stay
Free Parking Deep in the Onsen Hills
Why does free parking narrow the list to just two hotels here? Because most properties closer to the coast and the train stations charge for a space, treating parking as a paid extra rather than a given — it's the hotels furthest into the onsen hills, where public transport options thin out, that build free parking into the stay instead.
This riverfront hot-spring hotel behind Hadano, Hadano Yugawara Onsen Manyo-no-Yu, pairs mountain views with a bathhouse running an open-air bath, a private bath and a sauna. Free parking and a free transfer service both matter here because the hotel sits well outside easy walking distance of a station — most guests drive in, park for the length of the stay, and use the transfer rather than the car for local trips. Free Wi-Fi and a restaurant round out a stay built around not moving the car again once you've arrived.
Tsurumaki Onsen Jinya goes further still into the valley, a refined 4-star hot-spring inn with free breakfast and dinner included alongside its own bathhouse — an indoor pool, open-air bath and private bath. The free parking here pairs with a free transfer service too, and the inn's higher guest rating, 8.8 against Hadano Yugawara's 7.6, reflects a more polished stay for travellers willing to go further from the coast for it. Accessible rooms round out the property, useful for a multigenerational group planning to share the free parking for a single car.
Both hotels share a decision worth weighing before booking: neither sits within walking distance of Oiso Long Beach or Odawara Castle, so the free parking effectively locks in a car-based stay rather than a train-and-walk one. That trade-off suits a family already planning to rent a car for the wider Kanagawa trip, less so one relying on the JR Tokaido Line to move between towns. Both properties also include a free transfer, which softens the isolation somewhat for guests happy to let the hotel handle short local trips instead of self-driving every time.
For a stay that pairs free parking with dinner included, Tsurumaki Onsen Jinya is the stronger pick of the two — its rate covers both meals on top of the room, which offsets the extra driving time from the coast. Hadano Yugawara Onsen Manyo-no-Yu suits a slightly more budget-conscious version of the same trip, with the same free parking and transfer but breakfast and dinner priced separately. Either way, book ahead during Japanese school holidays, since free parking at a genuine onsen valley hotel is a rarer combination on this coast than it might first appear.
A traveler's takeWe drove up from Odawara Station to Hadano Yugawara Onsen Manyo-no-Yu and left the car in the free lot for two full days — the hotel's own transfer covered the one trip we made back down to the river for a walk, and not touching the car again until check-out day made the whole stay feel far more relaxed than our usual pack-the-car-every-morning routine.

Check availabilityWhy guests love itWe stayed at Tsurumaki Onsen Jinya on the last two nights of a longer trip specifically because I didn't want to plan another dinner, and having both meals included meant the evenings were entirely about the bathhouse — moving between the indoor pool and the open-air bath with nothing else on the schedule felt like the actual holiday, after a week of packed sightseeing days.

Check availabilityWhy guests love itWe drove up specifically for the free parking and transfer after a week of city-centre Tokyo hotels charging for every extra, and the mountain view from the bathhouse turned out to be worth the detour on its own — soaking in the open-air bath at dusk, with the river below and no other coastal hotel's crowd noise, felt like a different trip entirely.
Local tips
- 1Pick Tsurumaki Onsen Jinya over the other free-parking option if you want both meals included — it's the only hotel in this group that bundles breakfast and dinner with the room rate.
- 2Confirm your arrival time with the hotel if you're driving in after dark; the roads into these onsen valleys are unlit and slower than they look on a map.
- 3Use the free transfer service rather than the car for short local trips — both hotels offer it, and it saves relearning the valley's narrow roads twice in one stay.
- 4Pack for a car-based trip if you book either hotel — neither sits within walking distance of a train station, so a rental car or transfer is effectively required.
- 5Ask about parking capacity in peak season; even free lots at smaller onsen inns can fill up on weekends during Japanese school holidays.
- 6Pair a free-parking stay here with a day trip to Odawara Castle by car — it's a manageable drive from either hotel and avoids relying on infrequent local trains.
