About Kitamura Onsen | A Famous Hot Spring in Iwamizawa City, Hokkaido
Kitamura Onsen is a hot spring hotel located at 156-7 Akagawa, Kitamura, Iwamizawa City, Hokkaido. Situated near the former village office at the center of the former Kitamura district, it has long been cherished as a gathering place for local residents. Currently, it also functions as a public hot spring facility managed by Iwamizawa City under the name “Iwamizawa Kitamura Onsen Facility.”
History and Characteristics of Kitamura Onsen
Iwamizawa City, known as a major rice-producing region, was once also called “Yuamisawa” (bathing spring), carrying historical significance as a hot spring area. Kitamura Onsen is positioned as its inner sanctuary, boasting abundant spring water that flows directly from the back of the facility.
This geographical advantage eliminates the need to cool or heat the hot spring; the water drawn from underground can be poured directly into the bathing pools as-is. This is precisely why Kitamura Onsen achieves “100% source water circulation.”
Facility Overview
Kitamura Onsen Hotel features 16 guest rooms and accommodates both day-trip bathing and overnight stays. Beyond the hot spring facility itself, it functions as a comprehensive relaxation facility with a restaurant, clay bath sauna, sauna, and other diverse amenities for spending a leisurely day.
Source Water Circulation at 43°C | Spring Quality and Benefits of Kitamura Onsen
The greatest appeal of Kitamura Onsen lies in its unique spring quality.

Kitamura Onsen’s spring quality is classified as “Sodium-Chloride Strong Salt Spring (hypertonic neutral high-temperature spring).” A strong salt spring is characterized by extremely high salt concentration, notably containing salt levels higher than seawater.
Characteristics of Strong Salt Springs:
- High heat retention effect: Salt adheres to the skin and prevents sweat evaporation, causing the body to remain warm and cozy for an extended period after bathing
- Antimicrobial action: The salt provides sterilizing effects that keep skin clean
- Blood circulation promotion: Through thermal effects and osmotic action of the salt, blood circulation is enhanced
Significance of 43-Degree Source Temperature
Kitamura Onsen’s source temperature is 43 degrees. This temperature holds special meaning for hot spring enthusiasts.
Why 43°C is Ideal:
- No heating or water dilution needed: It falls perfectly within the comfortable bathing temperature range (42–44°C), allowing direct source water use
- Prevention of spring component deterioration: The bathing components do not undergo chemical changes through heating or cooling processes
- Optimal thermal effects: Neither too hot nor too lukewarm, it gradually warms the body from its core with ideal intensity
- Long bathing possible: This temperature does not cause dizziness, allowing leisurely enjoyment of the hot spring
Expected Benefits
Sodium-Chloride Strong Salt Springs are credited with the following therapeutic effects:
- Neuralgia, myalgia, arthralgia
- Cold sensitivity, peripheral circulation disorders
- Cuts, burns, chronic skin diseases
- Chronic gynecological conditions
- Frail constitution, fatigue recovery

Tips for Maximizing Your Enjoyment of Kitamura Onsen
Recommended Bathing Methods
Correct Bathing Method for Strong Salt Springs:
- Thorough preliminary pouring: Pour water over your body from the feet upward to acclimate yourself to the spring
- Start with half-body immersion: Rather than immediately submerging to the shoulders, begin with half-body bathing to acclimate
- Bathe for 10–15 minutes: Strong salt springs have high heat retention, so avoid prolonged soaking
- Take rest breaks: Exiting once and resting, then re-entering after hydration, maximizes effectiveness
- Light final rinsing: Leaving salt on the skin maintains heat retention (those with sensitive skin may rinse with fresh water)
