I've been surprised by the lack of tonic here. I consistently see gin in places, but I never see tonic.
You can find Schweppes Tonic at Costco here in Hisayama,so I woud expect the same at the Costco in your area if you are close.... You might be able to find it at your local "discount" liquor shop or large supermarket(if they sell booze).
