ATAMI Sekaie
ATAMI せかいえ
On high ground at Izusan in Atami, with every room facing the sea. Each has an open-air hot spring bath turned towards the water, and the view runs out towards Hatsushima. It keeps the number of rooms low.
Area
Atami is about 40 minutes from Tokyo by shinkansen, which makes it one of the easiest onsen towns to reach for a short stay. Many of its luxury inns sit on high ground above the town, looking out over Sagami Bay.
The inns on the heights, such as those around Izusan, are quieter but usually need a car or taxi from Atami Station. If you want to walk to the beach and the town, look for places closer to the shore.
