I believe it's made by HCL, but there are no manufacturer names or labels on the package. The writing is primarily in Japanese with english translations of some of the text. There is a piece of tape on the back, at the bottom that covers something. There's an address below the tape, in Japanese, that translates as "27-1 "izumiyamashita, Atami Ciy, Shizouka Prefecture, 413" followed by some telephone numbers.
