The secret treasure of Hojo is said to be one million gold pieces, with its location mapped out on three mirrors: Wind Thunder, Fire Dragon and Water Tiger; which is hidden inside the walls of Edo Castle. When the mysterious Fuma Ninja steal the Water Tiger, Shintaro goes undercover disguised (but not unrecognised) and determined to see the Water Tigers return. Deadly confrontation awaits Shintaro, and with help from Tombei and Shusaku the Fuma Ninja may have just met their match! The FUMA NINJA saga was one of the most popular stories in THE SAMURAI series, with plenty of ancient gadgetry to keep audiences enthralled and originally aired in Australia in 1965.
