Raiyantsuuri no Uta

The year is 1917, and under Japanese occupation, Taiwan suffers from terrible drought and famine. Residents of the Chianan Plain live in squalor, their lives defined by the daily struggle of carting water home. When Yoichi Hatta, a Japanese civil engineer, arrives with a plan to reshape the area's irrigation dramatically, the local residents are quick to call him a liar. Xu Yingzhe, the son of a poor farmer, takes issue with the outright rejection of Hatta's plan and tries to reason and grasp the situation. Hatta's scheme may seem crazy, but it could be the very thing that improves the strenuous lives of the Taiwanese people.

After suffering severe floods in 1753, the people of Senbon Matsubara in Shizuoka cooperate on flood prevention around the Kiso, Nagara, and Yuhi rivers. The people of Satsuma (Kumamoto Prefecture) endure great hardships after being forced to undertake the work by the central government, a subtle indication of the bad feeling that would foment into open rebellion the following century.

In an alternate timeline, Japan was divided after losing World War II: Hokkaido was annexed by "Union" while Honshu and other southern islands were under US sovereignty. A gigantic yet mysterious tower was constructed at Hokkaido and could be seen clearly from Aomori (the northernmost prefecture of Honshu) across Tsugaru Strait. In the summer of 1996, three 9th-graders had made a promise that one day they'll build an aircraft and unravel the tower's mystery, but their project was abandoned after the girl, Sayuri Sawatari, began experiencing sleeping sickness and transferred to Tokyo for better treatment. Three years later, Hiroki Fujisawa accidentally found out that Sayuri had been in a coma since then, and he asked Takuya Shirakawa to help him finding a way to revive her. What they don't know yet is that Sayuri's unconsciousness is somehow linked with secrets of the tower and the world.

The story follows a young girl and her family as they get trapped in Manchuria during the Russo-Japanese War.
