Bro Lundgren - you very lucky guy.
I am eager to try out Tonka and I hope she is there when I am next able to get back to Tokyo, hopefully later this year. In my opinion, there is nothing like a hot college-age Japanese Mistress. I think I will do a double with Ruiko and Tonka. I am dreaming about it already.
Yeah the entire Mistress situation here in Thailand is very lacking. I would much rather spend one hour with a Japanese Mistress than 3 hours with one or two Thai Mistresses as the costs are almost the same.
Club Eureka (I have never been) is east of Ikebukuro station.
Here is the map:

If you are visiting Kansai, I would assume you will be going to Kairaido - the best club west of Tokyo.
Let us know how it goes and also if you will be going to Club Fetish-SM and if you will attempt a session at Club Fin.
