Higashiyama Onsen, Aizuwakamatsu, Fukushima Prefecture
Harataki, Aizu Higashiyama Onsen (Day Use)
One of the strongest day-use picks if you want a gorge setting, the inn's own spring and an outdoor bath explicitly described as 100% source-flowing. Confirm day-use acceptance before travelling; tattoo access requires advance approval under a narrow foreign-visitor exception.
Check before bathing
- Tattoo policy
- Generally not permitted in the public and outdoor baths. The inn describes a limited exception for foreign tourists whose tattoos are for fashion, cultural or religious reasons, provided the guest or their travel agency contacts the inn in advance and confirms the guest is not affiliated with antisocial groups. This is not a general tattoo exception; obtain the inn's approval before visiting.
Spring & water temperature
- Spring-source temperature
- 58.0°C in the inn's analysis sample dated 2 October 2019.
- Bathing temperature
- Not published; 58.0°C is not a fixed temperature for the outdoor or indoor bath.
- Spring source
- Harataki spring.
- Spring classification
- Sodium-calcium sulfate-chloride spring (low-tonicity, weakly alkaline, high-temperature spring).
- pH
- 7.6 in the inn's analysis dated 2 October 2019.
- Flow rate
- 390 L/min by powered pumping in the 2019 analysis. The inn's current onsen introduction separately describes a 550 L/min supply; the dates or measurement definitions differ, so both figures are retained rather than reconciled.
- Water handling
- The outdoor bath is explicitly described by the inn as 100% source-flowing from its own spring, without added water, heating or circulation. The large indoor bath also uses the inn's spring, but the current page does not publish full treatment conditions for every indoor pool; the outdoor-bath claim is not extended to the entire property.
- Analysis date
- 2019-10-02
Bathing indications
The 2019 official analysis lists general bathing indications including chronic muscle and joint pain or stiffness, sensitivity to cold, peripheral circulation problems and fatigue. These are Japanese hot-spring indications, not a treatment guarantee.
The inn's current day-use rate is ¥1,100, taking precedence over an older ¥1,080 figure still shown by the Higashiyama tourism association. Admission may stop before 20:00 on busy days, so do not assume a 19:55 arrival will be accepted. The foreign-visitor tattoo exception requires advance confirmation under the stated conditions.
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.
