And so, BEWARE of Japanese tourists on bikes as Kailua town is experiencing.  Those tourists are generally oblivious to traffic and primarily concentrate on their own agenda with their companions riding bikes alongside them.  Traffic regulations are culturally disrespected throughout Asia and SE Asia, and so beware of such tourists.  On vacation in the U.S. and even Hawaii...they can more freely express themselves.  These promise to be bikers from hell...a B movie script.
