Atami Beach Line (熱海ビーチライン)

The Atami Beach Line is a 6.1 km private toll road along the Sagami Bay shore in Atami, Shizuoka, officially named the Atami Coast Motorway. It runs from Mongawa junction, by the Kanagawa border at Yugawara, to Higashikaigan cho by Atami Sun Beach. The road is almost flat and runs beside National Route 135, which climbs and winds through the hills above it.

In MF Ghost, Shuichi Shigeno's sequel to Initial D, the Beach Line carries two rounds of the fourth MFG season. Round 4, Seaside Double Lane, is a 21.7 km lap run six times: along the Beach Line from its Atami entrance to a U turn at the Mongawa tollbooth, then back into town on Route 135 to the Higashikaigan cho junction. Round 5, Atami Ghost, the final race of the series, also starts on the Beach Line, then heads through Atami and up into the hills on the Atami Ume Line, coming back down Shizuoka Route 20 through Sasajiri junction.

The road opened on 1 August 1965. Atami Infrastructure Management, owned by Kajima, the builder of the road, runs it today.

• From Mongawa the road runs south along the seawall towards Atami, with the sea beside it the whole way and the Manazuru Peninsula behind.
• Sunrise over Sagami Bay can be seen from most of the road, and the sun sits in a different spot against the Manazuru Peninsula as the seasons change.
• It drives as a gentle, nearly level coast road, where Route 135 above it has steep climbs and tight bends.
• Seaside Double Lane is told in the third season of the anime. Michael Beckenbauer wins it, and Kanata Katagiri's Toyota 86 is second. The waterfall that crosses the road and the jump ramps over it in the story are fiction.
• Atami Ghost closes out the manga, from volume 19 to the last volume, 23. Kanata wins it, with Beckenbauer third.
• On Atami Sea Fireworks Festival nights the fireworks go up over the bay beside the road.
• Best way to experience it: driving it yourself in your own car or a hire car.

• The toll is ¥600 for cars and kei cars and ¥400 for motorbikes over 125 cc, for each trip. Guides that list ¥500 or less for cars are out of date.
• The Mongawa tollbooth at the Yugawara end has automatic payment machines and a staffed centre lane that takes cash or ticket books only. The unstaffed Atami tollbooth on the northbound side takes cash, credit cards and cashless payment at automatic machines. The ETCX cashless service has ended.
• Books of 10 tickets for the price of 9 cost ¥5,400 for cars and are sold at the office beside the Mongawa tollbooth from 8:30 AM to 4:30 PM.
• The road is open 24 hours all year. It closes in storms and high seas, and the operator's homepage shows whether it is open.
• The whole road, both directions, closes for resurfacing from 5:00 PM to 8:00 AM on 9 and 10 November 2026, with 11 November held as a reserve night. Route 135 is the way round.
• On Atami Sea Fireworks Festival nights the lay bys between the Atami entrance and Izusan close from 4:00 PM to 9:00 PM and patrols are stepped up. Atami City sets the festival dates through the year.
• Stopping or parking on the road is not allowed, and photos cannot be taken outside the car. The operator points drivers who want to stop for the sea or the fireworks to Atami's city car parks.
