Jon McKinnon is your man. He supplies Briess and Hopunion products along with most everything else you could need quickly and professionally. One stop shopping! He spends most of his time in Japan, speaks Japanese fluently, and knows how to deal with phytosanitary requirements, and all the other import requirements. email@example.com (Tell him Phil sent you!) You may also be able to get Weyermann grain there, too. Email Sabina from their website. Also, there is a killer beer festival at Ebisu station, Tokyo this time of year. Good place to meet other brewers in Japan.
