I emailed a friend who used to be my Japanese tutor (both private then subsequently at uni), best teacher I ever had, to catch up and also offer assistance to her husband who I’d heard through a mutual friend was attempting to encourage the Japanese government to loosen their laws around home-brewing.
.. Turns out that her husband imports brewing equipment from California, where they live, to Japan and additionally has a consultancy which encourages and helps people to set up a brewery in Japan..
How fortuitious! So in return for my offer of help, I now have a return offer to help me set up my brewery when the time comes!
