In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

An American NASA spacecraft is hijacked from orbit by an unidentified spacecraft. The U.S. suspect it to be the work of the Soviets, but the British suspect Japanese involvement since the spacecraft landed in the Sea of Japan. To investigate, MI6 operative James Bond is sent to Tokyo after faking his own death in Hong Kong and being buried at sea from the HMSTenby(F65).Upon his arrival, Bond is contacted by Aki, assistant to the Japanese secret service leader Tiger Tanaka while watching sumo. Aki introduces Bond to local MI6 operative Dikko Henderson. Henderson claims to have critical evidence about the rogue craft, but is killed before he can elaborate. Bond chases and kills the assailant, taking the assailant's clothing as a disguise and escapes in the getaway car, which takes him to Osato Chemicals. Once there, Bond subdues the driver and breaks into the office safe of president Mr. Osato. After stealing documents, Bond is pursued by armed security, but is rescued by Aki, who flees to a secluded subway station. Bond chases her, but falls down a trap door leading to Tanaka's office. The stolen documents are examined and found to include a photograph of the cargo ship Ning-Po with a microdot message saying the tourist who took the photo was killed as a security precaution.Bond goes to Osato Chemicals to meet Mr. Osato himself, masquerading as a potential new buyer. Osato humours Bond but, after their meeting, orders his secretary, Helga Brandt, to have him killed. Outside the building, assassins open fire on Bond before Aki rescues him again. Bond and Aki drive to Kobe, where the Ning-Po is docked. They investigate the company's dock facilities and discover that the ship was delivering elements for rocket fuel. They are discovered, but Bond eludes the henchmen until Aki gets away; however, Bond himself is captured and knocked out. He wakes, tied up in SPECTRE operative Helga Brandt's cabin on the Ning-Po. She interrogates Bond, but he thinks he has managed to bribe his way to freedom. Brandt then flies Bond to Tokyo but, en route, she sets off a flare in the plane and bails out. Bond manages to land the plane.After finding out where the Ning-Po unloaded, Bond flies over the area in a heavily armed autogyro created by Q. Near a volcano, Bond is attacked by helicopters, which he defeats, confirming his suspicions that the enemy's base is nearby. A Soviet spacecraft is then captured in orbit by another unidentified craft, heightening tensions between Russia and the US. The mysterious spaceship lands in an extensive base hidden inside the volcano. It is revealed that the true mastermind behind this is Ernst Stavro Blofeld and SPECTRE. Blofeld seems to forgive Brandt for her failure to kill Bond, but as she leaves, he activates a mechanism that drops her into a pool of piranha. Blofeld instructs Osato to kill Bond.The Himeji Castle, location of the ninjas training.Bond trains with Tanaka's ninjas, during which an attempted assassination kills Aki instead. Bond is disguised as an Oriental in a fake marriage to Tanaka's student, Kissy Suzuki. Acting on a lead from Suzuki, the pair reconnoiter a cave and the volcano above it. Establishing that the mouth of the volcano is a disguised hatch to the secret rocket base, Bond slips in, while Kissy goes to alert Tanaka. Bond locates and frees the captured astronauts and, with their help, steals a spacesuit in attempt to infiltrate the SPECTRE spacecraft "Bird One". However, Blofeld spots Bond, and he is detained while Bird One is launched.Bird One closes in on the American space capsule, and US forces prepare to launch a nuclear attack on the USSR. Meanwhile, the Japanese ninjas approach the base's entrance, but are detected and fired upon. Bond manages to open the hatch, letting in the ninjas. During the ensuing battle, Bond fights his way to the control room and activates Bird One's self-destruct before it reaches the American craft. The Americans stand down their forces.Blofeld activates the base's self-destruct system and escapes. Bond, Kissy, Tanaka, and the surviving ninjas leave before the base explodes.
Who is the the Japanese secret service leader?
