The Place Promised in Our Early Days 雲之彼端 約定的地方 (2004) (Blu Ray) (Deluxe Edition) (English Subtitled) (Hong Kong Version)

 This edition comes with a 20-page booklet.

After the Separation in Japan in 1974 the northern island, Hokkaidō (or Ezo, as it is called in the anime), was occupied by the "Union" (referring to the Soviet Union). Also in that same year, the Union began the construction of a strange tower on Hokkaido designed by a scientist named Ekusun Tsukinoe. The anime follows the story of three friends living in Aomori, in northern Japan: two boys, Hiroki Fujisawa and Takuya Shirakawa, both child prodigies; and one girl, Sayuri Sawatari. In 1996, the three are in ninth grade, their last year of middle school, and they are fascinated by the Hokkaido Tower visible across the Tsugaru Strait to the north. Sayuri becomes close friends with the two boys.

The boys find a crashed Maritime Self-Defense Force drone plane and work on rebuilding the plane with the support of Mr. Okabe, their boss at a military plant. The three teenagers promise to one day fly to Hokkaido to visit the Tower. However, before they can do this, Sayuri mysteriously disappears during the summer.

Three years later, Takuya and Hiroki have stopped working on the plane, having taken different paths after the grief they suffered at Sayuri's disappearance. Takuya is working as a physicist at an Alliance scientific facility sponsored by the United States' National Security Agency, researching parallel universes alongside Ms. Maki Kasahara under the supervision of Professor Tomizawa. They know that the Hokkaido Tower, which began operating in 1996, replaces matter around it with matter from other universes, but they do not yet know why it does this for only a 2-km radius. Takuya becomes involved with the Uilta Liberation Front after he learns that Mr. Okabe is its leader; his factory workers are the other agents of the organization. Okabe signs Takuya on for an excursion to Ezo with Uilta.

Sayuri is revealed to have been hospitalized over the past three years, having developed an extreme form of narcolepsy; she has been sleeping continuously for most of the three years. Her mind is trapped in an unpopulated parallel universe, where she is all alone. Tomizawa has discovered that she is somehow connected to the Union's research into parallel universes and the Hokkaido Tower's ability to change the surrounding land into alternate possibilities, but Tomizawa keeps this information, as well as her whereabouts, secret from Takuya initially. Tomizawa is secretly working with the Uilta Liberation Front and lets Mr. Okabe know about Sayuri, while Mr. Okabe reveals that the Uilta Liberation Front plans to bomb the Hokkaido Tower to incite war against the Union, hoping that this will lead to the reunification of Japan.

The plane only seats two, so Takuya allows Hiroki to pilot the plane and fulfill their childhood promise. Hiroki manages to fly the plane across the strait to the Tower carrying Sayuri and a missile provided by the Uilta Liberation Front. When Sayuri finally awakens while the plane circles the Tower, the Tower activates and immediately begins to transform the surrounding area; the area under transformation grows to encompass much of Hokkaido. In the last few minutes of her coma, Sayuri realizes that when she awakes she will lose all her memories of her dreams of the past 3 years, and thus upon waking she weeps because, unknowingly, she lost the memory of her love for Hiroki. Flying back, Hiroki fires the missile, destroying the Tower and stopping the matter transformation. The film ends with Hiroki vowing to Sayuri that they will start their relationship anew.
