Oji drip coffee in Tokyo?

[MoGa]

Just saw the "Made in Japan" segment on the Oji Drip coffee 'machines' being used in the USA.
Since I'm in Japan for a while (until first Monday in April) I'd love to try some coffee made using this method.

Anyone know anywhere I can get it?
Easily accessible from Azabu Juban preferred.

I heard it is available somewhere in Ginza. I've looked in the Rappungi and Rappungi South areas, but could not find it there.
