No. C9310001
1. Source name:Haneda Airport Izumi Tenku Hot Spring

2. Source location:

2, Haneda airport, Ota-ku, Tokyo

3. Applicant for Hot Spring Analysis:

Kojun Nishima, Representative Director, Sumitomo Realty & Development Co., Ltd.

4. Spring Quality:

Iodine-containing high sodium chloride hot spring (hypertonic, slightly alkaline, low-temperature hot spring)

5. Contraindications, indications, etc. based on the spring quality of the therapeutic spring classification are as follows:(1) Contraindications for bathing
General contraindications
Active illness (especially with fever), active tuberculosis, advanced malignancy or severe anemia, serious heart or lung disease
that makes it difficult to breathe after slight movement, serious kidney diseases with swelling, gastrointestinal bleeding, visiblebleeding, and acute exacerbation of a chronic illness.
(2) Indications for bathing
General indications

Chronic pain or stiffness of muscles or joints (rheumatoid arthritis, osteoarthritis, lumbago, neuralgia, frozen shoulder, bruise,sprain, etc.), muscle stiffness in motor paralysis, decreased gastrointestinal function (upset stomach, gas in intestines, etc.), mild
hypertension, abnormal glucose tolerance (diabetes), mild hypercholesterolemia, mild asthma or emphysema, hemorrhoid pain,
autonomic instability, stress-related symptoms (sleep disorders, etc.), recovery from illness, fatigue, health promotion

Indications by spring quality type: Cuts, peripheral circulatory disturbance, sensitivity to cold, depression, dry skin(3) Methods and precautions for bathing
A. Precautions before bathing(a) Avoid bathing immediately before or after eating or drinking alcohol. Bathing while intoxicated should be especially avoided.
(b) Rest the body when excessively fatigued.
(c) Rest the body for about 30 minutes after exercise.
(d) Elderly persons, children, and physically disabled persons should avoid bathing alone.
(e) Before entering the bathing area, rinse the body by pouring hot water over the limbs to get used to the temperature.
(f) When taking a bath, especially immediately after waking up, hydrate yourself in advance by drinking a glass of water in order to avoid dehydration.
B. Bathing method(a) Bathing temperature
Elderly persons, persons with hypertension or heart disease, and persons who have experienced a stroke should avoid bathing at temperatureshigher than 42°C.
(b) Form of bathing
Half-body or partial-body bathing is preferable to full-body bathing for those with impaired cardiopulmonary functions.
(c) Bathing frequency
During the first few days of bathing, the frequency should be once or twice a day, and may be increased to two or three times a day as the person
becomes accustomed to it.
(d) Bathing time
The duration of each bath should be 3 to 10 minutes at first, depending on the temperature of the bath, and may be extended to 15 to 20 minutes
as the person becomes accustomed to the bath.
C. Precautions while bathing(a) Except for exercise baths, bathing should be done quietly, with only light movement of arms and legs.
(b) When getting out of the bathtub, exit slowly so as not to stagger.
(c) If experiencing dizziness or an unwell feeling, ask for help from someone nearby, get out of the bathing area slowly, keeping the head low, and lie
down and wait to recover.
D. Cautions after bathing(a) Do not rinse off hot spring ingredients adhering to the body with warm water, but wipe off the moisture with a towel, keep warm and rest for about
30 minutes after dressing. (However, people with sensitive skin should rinse off hot spring ingredients with warm water as necessary if the spring
has a highly irritating quality, [e.g., acidic or sulfuric springs] or if chlorine disinfection is used).
(b) To avoid dehydration, drink a glass of water.
E. Hot-spring bath symptoms caused by prolonged bathing
Hot-spring bath symptoms such as discomfort, insomnia, gastrointestinal symptoms, or dermatitis may appear approximately 3 days to 1 week
after the start of hot-spring therapy. While such symptoms are present, the patient should discontinue bathing or reduce the frequency of bathing
and wait to recover from such symptoms.
F. Other.
In order to maintain the cleanliness of the bath water, no towels shall be placed in the bathing area.
(Note) This Appendix serves as reference material required for posting in accordance with Article 18 of the Hot Springs Act.
