Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.

Osaka's saunas aren't just about superior facilities. Within them dwells the intense service spirit and entertainment mindset unique to a merchant city, one that strives relentlessly to delight its guests. This time, I set out on a journey to savor the overwhelming intensity and brilliance of Osaka sauna culture down to the very core. Starting at SPA&SAUNA Suishun Hattori Ryokuchi, I hopped straight over to Tsurumi Ryokuchi Yumoto Suishun to experience firsthand the true strength of the Suishun brand. Then I pushed past my limits at Utopia Shiratama Onsen, where an exquisite ice bath awaited, and finally reached total bliss in the Asia Zone of the massive theme park SPAWORLD HOTEL&RESORT. Let me take you on this exceptional sauna journey into the true essence of Osaka sauna culture.
