CityHeaven, this one calls you to validate who you are
r.caskan.jp - (example https://r.caskan.jp/spad)

https://estama.jp/ - este site, broad coverage across Japan
https://www.esthe-ranking.jp/ - esthe site, commonly associated with Tokyo
https://www.ezaru.com/ - outdated, but my current go to esthe site as it has categories you can sort by, things like body wash etc
https://www.dto.jp/ - probably most popular delivery health website for south areas of Japan
https://www.26style.net/top/ - good free review site for soaplands
