An open, urban sento accented by an outdoor pool and automatic löyly sauna
Tokyo Nakano City
"Aqua Higashinakano" is a sento in Nakano Ward, Tokyo, known for its bright and open atmosphere. All water in the bath area uses highly purified soft water made from naturally sourced underground water, allowing for a gentle bathing experience that is kind to the skin. The sauna is set at a high temperature above 100°C, and the automatic löyly and fan-assisted airflow every 20 minutes strongly encourage sweating. Its biggest highlight is the outdoor mini-pool in the open-air area, where guests can cool down after the cold plunge bath or even swim. With facilities such as carbonated springs and silky baths, it offers a refreshing experience that goes beyond the usual sento.
