Once upon a time, I read about Murayoshi charcoal products. It was in Men's Health, or GQ, or some such silliness. It's pretty awesome stuff, though. Oak wood carbonized in whole logs rather than little chunks.
So way back when, I sent Murayoshi an e-mail. They encourage it on the website, to determine pricing and shipping costs. It got bounced back, mailbox full. Sent another one a couple weeks later. The same response.
Repeat that 4 times over the last year or so, and you've got my current situation. Does anyone know of another US retailer of bincho charcoal? Or how to get through to Murayoshi?
