We searched for radio bursts towards 51 Peg, τ Boo, ν And and 55 Cancri, which were found to have "hot Jupiter" companions. The star 51 Peg has a planet with 0.5 M_{Jup} (lower limit) and 4.23 day period. The star τ Boo has a planet of 3.7 M_{Jup} and 3.31 day period. Such planets are called "Hot Jupiter". We made a non-thermal radio emission model of magneto-electric environment between the stars and their planets. Since a detection of signals is expected, we made observations at 8.6 GHz with Mizusawa 10-m telescope. From 1996 to 2000, we observed with a detection limit of 10 Jy using a position-switching method. Since 2001, we changed to beam-switching method, and achieved a detection limit of 1 Jy. No radio burst signals were detected.
