Do Tamiya stores in Japan sell old models?

Hi all! I've been wanting to get this old 1/20 F1 model which is the F189 Portuguese GP (Mansell's Ferrari 640). I'm currently in Tokyo and planning to drop by the Tamiya Plamodel Factory in Minato City. Any chances I can get one? There are several in Mercari, but I can't register without a local sim card.
