Onsen FAQ

Frequently Asked Onsen Questions

Q: What exactly IS an Onsen?

To describe an Onsen as a hot spring doesn't begin to describe the real thing.  North American hot springs tend to be either over-developed resorts with everyone in bathing suits, or remote natural springs frequented by naturists, the sole purpose being just to sit in some hot water. Onsen are intended as a total cleansing experience for both the mind and body.  The best onsen resorts feature quiet, traditional "Ryokan" inns with tatami-mat rooms and both indoor (O-Furo) and outdoor (Roten-Buro) baths.  You should plan on staying at least one night and hitting the baths at least 5 times.

Q: Do men and women bath together?

TV shows and movies such as Shogun have given many the impression that mixed bathing is a regular feature of Japanese Onsen.  Even Japanese Onsen shows and advertisements tend to feature very attractive young women.  However the influx of Western culture and ideas has resulted in a separation of male and female baths in almost all cases with the possible exceptions being in the remote countryside.  Even so, you are more likely to find yourself sharing the bath with a group of grannies then a flock of winsome nymphs.

Q:    Which Onsen are close to Tokyo?

There are actually several Onsen right inside Tokyo one with coal black water!  However these tend to be situated inside modern buildings.  The closest "real" Onsen are located in places like Hakone and Atami both a short train ride from Tokyo with the latter being a bit more commercial.

Q:    What is the difference between an Onsen and a Sento?

An Onsen is a real hot spring resort as described in the first question.  Sento are the neighbourhood bath houses that flourished in the days before it was common for a Japanese house to have a bath.  Although they are dying out, there are still some beautifully decorated Sento to be found.  A good resource is Yashoroyu's page.

Q:    How much does it cost to visit an Onsen?

Prices range from ¥1000 (US$10) for a quick dip to over ¥20,000 (US$200) for an overnight stay.  Per person!  Naturally, you will find everything in the range between.

Q:    Do I have to stay overnight at a Ryokan (Inn) or Onsen Hotel to go in the bath?

A:   Not necessarily.  Many Onsen resorts offer non-resident use of their facilities.  This is referred to as "Nyu-yoku only". Onsen near Tokyo like Hakone have many places where the "Hi-Gaeri" (return-in-one-day) visitor can enjoy a soak.

Q:    How do I get to an Onsen?

Since Onsen are very popular with Japanese there tend to be several forms of access.  Well-known Onsen will be located near railways or will at least be a short bus ride from a railway station.  Without a doubt, the trains are the best way for a visitor to get around Japan.  A train-lover's paradise, Japanese trains are clean, run on time and the rail system is extensive.  The best deal is to buy a JapanRail Pass before you leave for Japan.  They can be ordered through your travel agent or from JTB.  It is also possible to rent a car but the price is extremely high along with the price of gas which tends to be at least twice hat of North America.  Road signs off the major expressways and away from major cities will have no English or even romanized Japanese.  Japan drives on the left like England.

Q:    Is there a best time of year to go?

Onsen can be enjoyed anytime of the year, however you should definitely avoid the Japanese holiday times of O-bon (1st to 2nd week of August) and O-Shogatsu (roughly Christmas and New Year's).  Since you are putting yourself in hot water, colder times such as winter, and early spring / late fall are best.  Personally, my ultimate Onsen experience is to be sitting in a mountain-side Roten-Buro under the stars surrounded by deep snow and listening to the temple bells softly ringing in the New Year.
