In retrospect, one of the more glaring faults of Hawaii Five-O is its continual use of non-Asians in Asian featured parts. Sometimes, it kind of works: Keigh Deigh wasn't Chinese - or Asian at all - but he was sufficiently "exotic" that he could pull off Chinese spy Wo Fat. Most of the time, however, it doesn't, and this episode features perhaps the worst of the lot; Ricardo Montalban as Japanese crime lord Tokura.
Montalban was a very charismatic actor and was always worth watching, but the very idea of the very Mexican Montalban as a former Japanese submarine crewman turned organized crime kingpin is unbelievable to the point of being surreal, and pretty much ruins the episode.
The actual story is pretty interesting, though, particularly the climax, where McGarrett tricks Tokura into confessing by convincing him that he's going to be assassinated by Bushido.
