About the water
Atami City counts over 500 sources with a total flow approaching 20,000 litres a minute, about 90% of them above 42 °C and averaging around 63 °C. According to Wikipedia some 80% are sodium–calcium chloride springs, the hottest reaching 98.2 °C, mildly alkaline. Chloride water leaves salt on the skin and is said to keep you warm after bathing; the city describes it as strongly heat-retaining. It is clear and odourless. The old Kawarayu spring, the city notes, was so salty that bathers turned the clear water cloudy, so salinity varied from source to source. The foot bath at the station runs sodium–calcium chloride-sulfate water at around 40 °C.

Three things not to miss
Photo information
The Oyu Geyser and the 'seven springs' walk
Kamishuku-cho to Ginza-cho and Sakimi-cho, within about 20 minutes' walk of the station The Oyu was once called one of the world's three great geysers; it fell silent after the 1923 earthquake, was rebuilt as an artificial geyser in 1962 and designated a city cultural property in 1977. It now erupts for about 3 minutes every 5, 8:00–19:00, free. With Kawarayu, Sajiro, Seizaemon, Furo, Kosawa and Nonaka it makes seven marked springs to walk between.
Walking the circuit shows where Edo-period townsfolk drew water, which spring they bathed their eyes in and whose steam warmed their buns. At Kosawa-no-yu you can still cook eggs in the steam.[4][6][7]
Atami Ekimae public bath and the Ieyasu-no-yu foot bath
Right outside Atami Station An old-style public bath a minute from the station: 500 yen adults, 200 children, 100 infants; closed Wednesdays. The free Ieyasu-no-yu foot bath outside the station (9:00–16:00) is a 36 m² pool of sodium–calcium chloride-sulfate water, refilled every morning.
Within five minutes of stepping off the Shinkansen you are in Atami's water. That short distance between city and spring sums up four centuries of Atami.[8][9][5]
Atami Bay fireworks
Atami Bay, off the port In the 2026 season, 14 shows between 26 April and 25 December (15 including 21 February 2027): 20:15–20:40 in July–August, 20:20–20:40 in other months.
Launched from the quay in Atami Bay. You can walk down from the bath to the shore in time for the first shell.[10]
The story
The spring moved from the sea to the hill
The name Atami, 'hot sea', is said to come from boiling water that once gushed from the seabed. According to the city, in 749 the monk Mangan of Hakone led the undersea spring up to the hillside, to the spot where the Oyu Geyser now stands. In 1604 Tokugawa Ieyasu stayed for a seven-day cure, and later had the water packed in barrels and carried to Edo Castle. This 'okumiyu', the drawn water, made Atami famous across Japan as the shogun's spring.[2][3]
The town whose geyser fell silent
The Oyu was called one of the world's three great geysers; Edo-period records say it erupted six times a day, hard enough to shake the ground. It weakened from the mid-Meiji period and stopped after the Great Kanto Earthquake of 1923. The city rebuilt it as an artificial geyser in 1962 and listed it as a cultural property in 1977; it now erupts for about three minutes every five, from 8:00 to 19:00. The six other springs used since the Edo period survive as stone markers and spouts, and together they make the 'seven springs' walking route.[6][7][4][3]
Four hundred years of city and spring
Damaged in the 1923 earthquake, Atami recovered fast when the railway reached Atami Station the following year. By the late 1950s it was the classic honeymoon destination, and it was already famous as the setting of Koyo Ozaki's novel 'Konjiki Yasha'. Visitor numbers fell after the bubble economy and, per Wikipedia, bottomed out in 2011 before the much-reported 'Atami revival'. Many hotels take day bathers; the Atami Juraku Hotel, three minutes from the station, charges 2,000 yen from 13:00 to 21:00.[3][11]
Hot water one minute from the train
Outside the station is the free Ieyasu-no-yu foot bath (9:00–16:00), a 36 m² pool refilled with fresh spring water every morning. Across from it the Atami Ekimae bathhouse is an old-fashioned public bath, 500 yen, closed Wednesdays. Twenty minutes downhill bring you to the seven springs and the shore, where fireworks go up over the bay 14 or 15 times a year. Bath, town, sea and fireworks all connect on foot from a Shinkansen station.[5][8][7][10]
