I have a test where I am given the following article, what is an answer for the question: What secret organization does the woman Bond meets at a sumo match work for? ?

American NASA spacecraft Jupiter 16 is hijacked from orbit by an unidentified spaceship. The United States suspects it to be the work of the Soviets, but the British suspect Japanese involvement since the spacecraft, after having "swallowed" Jupiter 16, 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 HMS Tenby.
Upon his arrival, Bond meets a mysterious Japanese woman while watching a sumo match. She introduces Bond to local MI6 operative Dikko Henderson, who 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 is driven in the getaway car to Osato Chemicals. Once there, Bond subdues the driver and breaks into the office safe of president Mr. Osato. After obtaining certain documents, Bond is pursued by armed security, but is rescued by the woman he had met earlier, who flees to a secluded subway station. Bond chases her, but falls down a trap door leading to the office of the head of the Japanese secret service, Tiger Tanaka, who reveals that the woman is his assistant Aki. 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. While at Tanaka's spa, Bond meets with Aki again and they spend the night together.
