 In the original script, the Japanese businessman (Taka) killed by  the freak hailstorm in Japan was involved in some sort of illegal  insider trading scam with the New York stockbrokers who bribed their  way onto the bus (and apparently still didnt survive). Later this  secondary storyline was discarded, and Takas cellphone conversation  with the New York stockbrokers was dubbed over to become a chat with  his wife/significant other. The original Taka/stockbrokers scene is  on the DVD.
