[Notice] Spa LaQua x POLA / An event to achieve beauty through hot springs and skin science

Fair announcement

LaQua,Spa

Spa LaQua will be open from January 19th (Monday) to February 18th (Wednesday), 2026.

We will be holding a collaboration event with the cosmetics brand Pola (Shinagawa-ku, Tokyo).


At this event, POLA will conduct a unique "skin science analysis of hot springs."

We will suggest bathing methods based on the analysis results, such as "spring quality that allows beauty ingredients to penetrate easily" and "hot springs recommended for dull skin."

After relaxing in the hot springs and sauna, you can enjoy a luxurious moment of conditioning your skin with Pola's high-quality skincare products.


During the period, the building will be decorated with original noren curtains, and admission discounts and novelty gifts will be available.

A skincare seminar by a POLA researcher will liven up the event.

In addition, beauty and relaxation salons will offer limited-time menus tailored to the quality of the spring water.

1. In the men's and women's spa zones, bathing methods and skincare based on the results of the "analysis of hot spring skin science" will be introduced.

●What is skin analysis related to hot springs?

Cosmetics company Pola is applying skin analysis technology developed through years of cosmetics research to scientifically verify the skin-beautifying effects of hot springs.

This initiative involves collecting water from the bathtub's hot water, which comes into contact with users' skin, to demonstrate its skin-beautifying effects.

You can feel the effects after just one bathTo confirm the skin benefits, we conduct evaluations based on dermatological research.


Based on the results of skin science research conducted at Koishikawa Onsen (Spa LaQua),

Spa LaQua has been certified as a "Soothing Booster Hot Spring"facility.
