Buenos dias from Japan. I don't know Master Daigoro and his assistant Suzumaru can understand Español, however, we Japanese learned the Latin origins language; English. From a professional point of view, Español is a sister language such as Français and Italien. Some basic words must be understood for the beginners, however, if you use English as an assistant language, you can make contact with them. Some of us are not getting used to speaking in English, but we Japanese (including Maestro Daigoro, around my age) can understand you; for Young assistant Suzumaru learned English at much earlier age. If many of them learned secondary foreign languages such as Español or Français, Germanique, we can understand by the senses.
