Advertising in Japan is very expensive and basically unavailable for Czech entrepreneurs. For this reason, it is best to link up with local importers and distributors to promote the product in an appropriate and effective manner. The only well-known Czech brand in Japan is Bohemia Crystal, which is supported, among other things, by the presentation of a crystal cup by a representative of the Czech Republic's Foreign Office six times per year to the winners of Japan's largest professional sumo tournaments.
