Phantom Agents (忍者部隊月光, Ninja butai gekkō) is a Japanese action television series of 130 black and white episodes that aired from 3 January 1964 to 2 October 1966.
They wore "pudding basin" motorcycle helmets, and in the earlier episodes they ran everywhere in single file, but later graduated to a Toyota Crown Saloon.
The Phantom Agents were armed with ninja weapons such as shuriken and used guns "only as a last resort," as was patiently explained to the only female member in the title sequence of each episode.
They had the ability to jump backwards up onto the limbs of trees and could hold a piece of cloth with a brick pattern on it in front of them and thus blend into the wall behind them, becoming invisible to their opponents.
It was not a ratings success there, at least partly due to the sporadic programming schedule, and the fact that it was often broadcast at times inconvenient for schoolchildren to watch.
