Briefly: Suspended in Language will soon (where “soon” is a ways off, really, since translation takes a while!) be available in Japanese from Kodansha and Korean from Green Knowledge.
Kodansha — via their Blue Backs line of books — did a wonderful job with Feynman and I’ve been very pleased with all the Korean editions of my books as well, so I’m excited and pleased to have my two physics heroes meet up out on the Pacific Rim.
