1945: Kantaro Tagruato founds a mining company in Kyūshū, Japan’s southernmost island, named 力の手 (Hand of Power). The company goes on to become very successful in the next few decades.
1989: Ganu Yoshida, a businessman involved in off-shore drilling, purchases all shares of Hand of Power, a company now faced with scandals and a steady decline. Yoshida becomes C.E.O. of the company and subsequently renames it as the the Tagruato Corporation.
May 28th, 2007: Tagruato releases a statement claiming that they have completed comprehensive testing on Seabed's Nectar, which they expect to reveal unmatched health benefits.
2007: the Ravaille Research Centre publishes an article on Seabed's Nectar, claiming that it has significant effects on the human body.
2007: Tagruato releases a statement claiming that the Ravaille Research Centre's article on Seabed's Nectar is false and that legal action is being taken against them.
2007: the anti-Tagruato environmental activist organisation T.I.D.O. Wavesends some of its members to Tagruato's off-shore drilling rig Chuai Station, including Teddy Hanssen. Teddy goes missing following this assignment, but manages to send his girlfriend Jamie Lascano some evidence from the station, including a sample of Seabed's Nectar. Jamie assumes that Teddy is lying about his disappearance in order to end their relationship. Interestingly, she consumes the sample of Seabed's Nectar and can be seen acting unnaturally hyperactive in the last of a series of video messages she sends to Teddy. She is found passed out during the party at the beginning of the Cloverfield film.
November 28, 2007: according to T.I.D.O. Wave, a marine biologist working for Tagruato makes a "magnificent discovery" but is subsequently killed along with his family by a gas explosion. This discovery is presumably of the Large Scale Aggressor (LSA) that attacks New York City during the events of the Cloverfield film, nicknamed Clover. His death is most likely an assassination by Tagruato to prevent his discovery of the LSA from going public.
December, 2007: a whistleblower working at Chuai Station claims that there is no oil at the station's location and Tagruato must have known this before they built it. The whistle blower also leaks sonar images indicating something large in the water around the rig, presumably the LSA. The Military Commentary from the Cloverfield Blu-ray supports this, stating that the LSA may have already been discovered by Tagruato. The commentary suggests that both Chuai Station and the Hatsui satellite may actually have been used to research or keep track of the LSA.
December 27/28, 2007: Chuai Station is destroyed. Tagruato blames the destruction on an alleged terrorist attack by T.I.D.O. Wave. Teddy Hanssen's sister, Alysse Hanssen, follows leads while searching for her missing brother. One of this leads reveal photos apparently taken by Tagruato submarines. These photos confirm that Human Scale Parasites (HSPs) were present on the seabed around Chuai Station and that the station was in fact attacked by the LSA.
2007-2008: Tagruato releases a statement claiming that Bold Futura launches a satellite named Hatsui into orbit. After a month spent in orbit, a Japanese government satellite named ChimpanzIII loses a piece which falls into the Atlantic Ocean. This is the same satellite piece that is seen falling into the sea at the end of Cloverfield. Tagruato claims that the Hatsui satellite is being used to locate the rogue piece.
May 22, 2008: as documented in the film Cloverfield, the LSA emerges from the Atlantic Ocean and begins to lay waste to New York City, presumably having been perturbed by either the rogue piece of the ChimpanzIII satellite or Tagruato's research. Interestingly, the Special Investigation Mode of the Cloverfield Blu-ray states that the HSPs that fell off the LSA during its attack contained high levels of Seabed's Nectar in their blood.
May 23, 2008: after several unsuccessful attempts to neutralise the LSA, the US military initiates the Hammerdown Protocol. A large bomb is dropped on Manhattan, presumably resulting in both the destruction of the city and the LSA.
