Outside of Japan

There is no shortage of mail-order brew supply stores in the U.S. and elsewhere.

F. H. Stienbart, Portland, Oregon. The online store has a large selection of ingredients and equipment. The staff is helpful and responsive, and I've requested items which are in the store, but not listed on the on-line site. I buy from them regularly, and they will ship to Japan, including heavy items.
