How To Make A Reservation

Cancellation Policy

Spa - We ask guests to guarantee all reservations with a credit card. This card will not be charged unless you cancel or change without giving us adequate notice. For baths and treatments, we require 24 hours notice to cancel or change without a penalty.

Lodging - Cancellations fourteen or more days prior to the reservation will not be charged for the change. Cancellations from 7 to 14 days prior will be charged for the first night and will receive a gift certificate in the amount of the first night's stay for future services. Cancellations from 2 to 6 days prior will be charged for the first night's stay. Cancellations after 4 pm of the day before the reservation will be charged for the entire reservation. Gift certificates may be used for spa, lodging, massage, and retail. They have no expiration date and are fully transferrable.

Cancellation Penalty Exceptions - If your cancellation is due to COVID concerns, proof of a positive test will absolve you from the cancellation fees. The positive test may be for one of your party, a household member, or someone you work closely with that requires your absence from work.

Alcohol & Beverages

Heat and high altitude will exacerbate the effect of alcohol (or any form of psychoactive substance, even coffee). Impaired judgment and loss of consciousness can result. Because of this, we strongly discourage the consumption of alcohol before or during activities at the Waves. If you do bring glass containers, please inform us upon check-in so that we can provide a bottle caddy and/or non-breakable cups. Glass, hard floors, and bare feet are a bad combination.

Children & Under 18

At Ten Thousand Waves, we are inclusive, not exclusive. We welcome well-behaved children in our lodging rooms and baths.  There is no charge for children under 4 feet in any private tub (2 kids maximum per adult). Anyone under the age of 18 must have the permission of an adult to use our facilities.  


Food & Drink

Our great Japanese restaurant izanami is open from 4:00 pm until 8:00 pm every day except Monday. Drinks, but not food, may be taken into hot tub areas. Consumption of alcohol before or during bathing is not advised.

Health Concerns

Hot water and sudden temperature changes can be stressful to your body. If you are pregnant or have chronic health problems, always consult your health care provider before bathing.

If you have recently been exposed to COVID or come from a region where the infection rate is high, we would suggest waiting 14 days before visiting.

Nudity / Bathing Suits

All baths are clothing optional. Please feel free, however, to wear suits in any of the facilities (Rentals available at the front desk for $4.00, tax included 

Therapeutic Massage is done without clothing. Our therapists are specially trained to drape discreetly with sheets and towels. Shiatsu massage and Ashi Anma Foot massage are done wearing loose clothing. These treatments may be a better option for the modest.


There is plenty of parking at street level, and limited additional parking at the spa level, approximately 60 vertical feet higher. Those with physical limitations should consider the upper lot. The walk from the lower lot, however, is very pleasant and provides a good transition from your busy day to the tranquility of Ten Thousand Waves. Passengers may be dropped off at the entrance to izanami or the spa. There are two accessible spots very close to the spa front door. We have a shuttle service from the lower parking lot. Look for the call boxes to summon the van.


Special Needs

A number of our massage rooms, baths, and lodging rooms can accommodate individuals with mobility issues or disabilities. There is a shuttle service from the main parking lot to the spa--call button is located at the bottom of the footpath in the main lot. Unloading and loading of guests may be done in front of the main entrance to the spa, adjacent to which are handicap parking spaces. 

The spa has 3 levels. An elevator is available if stairs are a challenge

Please mention special needs when making your reservations.

Water Cleanliness

We use a state-of-the-art purification system for all baths, utilizing ultraviolet light, hydrogen peroxide, and ozone. Chlorine is not used in any bath. The entire water content of each tub passes through the sanitation system every twenty minutes. We perform bacterial cultures weekly on all tubs to ensure that all systems work properly. Often the result is drinking water quality. See 'Keeping Our Water Clean' for a description of what we do to assure absolutely clean and sanitary conditions.The source of the highly mineralized water used in the baths is a 900-foot deep well.

What To Bring

Here, as in Japan, we ask you to take a shower prior to entering the baths or treatments. This maintains the quality of our water, makes treatments a good experience for guest and therapist, and allows you to rinse off the cares of your everyday life before your experience at the Waves.

We provide, at no charge:

  • Kimono and sandals (if receiving both tub and massage)
  • Towels
  • Shower gel
  • Shampoo
  • Conditioner
  • Lotion
