Mikawa, Hakusan, Ishikawa Prefecture
Mikawa Onsen Motoyu Honda
A worthwhile low-cost natural-spring stop between Kanazawa and Komatsu, especially if you like dark, coffee-coloured moor water and a sauna. Choose another facility if you need an outdoor view, early-morning bathing or a family bath currently in service.
Check before bathing
- Opening hours
- 10:00–22:30; closed Wednesdays. Open when Wednesday is a public holiday, with a possible closure the following day according to the Ishikawa tourism page.
Spring & water temperature
- Spring-source temperature
- 31.9°C in the Japan Hot Springs Association database; the analysis date is not given, so this is not treated as a 2026 re-analysis.
- Bathing temperature
- Not published. The 31.9°C reference is not a bathing-pool temperature.
- Spring source
- The facility's own underground spring; the current official information does not publish a well number.
- Spring classification
- Described by Hakusan tourism as a coffee-coloured natural moor spring containing plant-derived organic matter; the Japan Hot Springs Association classifies it as a chloride spring, while a 2026 hands-free plan calls it a mildly saline spring. The differing published descriptions are retained rather than reconciled.
- pH
- Not published in current first-party pages. An older third-party pH 8.6 figure is not substituted.
- Flow rate
- Not published in current first-party pages. An older third-party figure of 55.9 L/min is not substituted.
- Water handling
- Hakusan City and Ishikawa Prefecture tourism confirm that the facility uses 100% natural spring water from its own source. The current first-party pages do not fully specify water addition, heating, circulation filtration, disinfection or overflow conditions for each bath. “100% natural spring water” does not mean 100% source-flowing; the Japan Hot Springs Association currently lists no source-flowing bath.
- Analysis date
- 2026
Bathing indications
Current official information focuses on the coffee-coloured moor water and how it feels. Older analysis and booking pages contain indications, but these are not presented as a personal treatment claim or medical advice.
The family bath is listed as temporarily closed by Hakusan City's current tourism page. The facility website still has a general family-bath description, so do not assume it is available for a 2026 visit.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
