>>6442923I don't live in Berlin but sometimes you can find gashapon vending machines in malls, supermarkets etc. They're usually filled with tomy stuff like Super Mario, Hello Kitty, Pokemon and the likes.
If you can find one of those trendy scene stores where they sell nerd/weeaboo related items you might find the cooler stuff. Where I live there used to be a shop that got machines from Japan you had to feed with yen-coins that you could trade for euro coins and they even sold blind boxes with nendoroid puchi, figmas etc. so, I guess you might be able to find machines if you know where to look for them.
Managed to locate a store in Berlin that sells Japanese/ anime merch. Maybe it helps.
