You can reach Tokyo Hy-Power by e-mail, fax, or postal mail. Nobuki Wakabayashi handles most if not all of the English language correspondence, and I have found him to be quite responsive. I have never tried to phone them, but the phone number is provided for brave souls who might wish to try it. You can reach THP at:
TOKYO HY-POWER LABS, INC.
1-1, HATANAKA 3-CHOME, NIIZA,
SAITAMA 352-0012 JAPAN

Updated information, if and when it is received, will be posted here and to the reflector.
