Milk Kefir in Tokyo/Yokohama?

Hello!

I’m after some milk kefir live grains, also known as Tibetan Mushrooms. These look like bits of cauliflower. You put them in milk and they turn it into yoghurt. Anyone know where I can get some, or has anybody’s divider and ready to share?

I don’t that I can get grain sachets. I do not want these. I want the live thing itself. Please PM me if you can help.
