"Bathing cleans the mind and soul." So said Misato of Neon Genesis Evangelion... Indeed, bathing is a great place to relax and help relieve a bit of stress.

But suddenly, a mysterious group of women appears and starts a dynamic performance in hot springs!

Synchronized swimming in spas!? A relaxing space had suddenly turned into an exhilarating show-house. Can't relax anymore though!

This movie is called "SHINFURO" - which is an invented word that docks the words "synchronized swimming" with "furo (bath)".

The synchronized swimming was performed by "RAIKA ENTERTAINMENT", lead by Raika Fujii (former Olympian). Considering how synchronized swimming is done in a much deeper swimming pool, doing it in a shallow spa seems quite hazardous. But they cover it with their professionalism - all with advanced technique and well-rehearsed choreography.

Even the music is unique: it uses the natural sounds captured in Oita prefecture including the sound of someone dipping into a spa or putting some food in a deep fryer. The main music is "Hana", a well-known piece by Rentaro Taki (1879-1903).

As you can see in the video, Oita not only features the greatest number of hot springs, but also may kinds of spa - including mud pool, carbonated springs, and cold spring.

There are 11 different hot springs featured in the video - which one would you like to dip into?
