A wireless terminal includes: an intercept mode evaluation unit configured to evaluate a congestion state of wireless resources, based on a communication state of other terminals intercepted during executing an intercept mode, which is a mode of intercepting communication by the other terminal; and a transmission mode execution unit configured to execute a transmission mode, in which the wireless terminal performs transmission and reception, without executing the intercept mode when the intercept mode evaluation unit evaluates that an off-time has set in.
