Sadly, we are at a point now, where we are losing many of these classic Toho actors and actresses. My favorite role of Mr. Takashima was in "Frankenstein Conquers the World", where he and Nick Adams sort of played the ying and yang - Tadao the obsessed one with the Frankenstein monster (even to a point of wanting to kill him to advance his damn research), while Nick was the calm, cool and collective presence that was badly needed.
RIP Mr. Takashima
