Where can I find an isolation tank in Tokyo?

I was wondering where I can find an isolation tank / flotation tank in Tokyo? I know there used to be one in Shirokane-takanawa, but it seems to have closed down.

Hi, ishiki.

The relaxation (healing) facility you mention has closed down since 2011.
According to the Wikipedia Japanese version, there is no such healing clinic in Tokyo right now.

Currently, an isolation tank / flotation tank available to you is only in Okayama and Okinawa:

Lenka (in Okinawa)

Hikari Clinic / Cocoon (in Okayama)

To access to these healing facilities,
you have to move from Tokyo by bullet train or by air.

Hello! There is a tank available for public use in the Nagoya area. Would be a little closer to you than the Okayama one. Contact "Michael Serro" on Facebook or mikerithchin@weaverkuni via twitter for more info or if you have any questions . Hope this helped.

Twitter account for isolation tank in Nagoya, has changed from mikerithchin@weaverkuni to isolationtankjapan@weaverkuni

The fb page is "Isolation Tank Japan" , thanks
