She has published a series of highly original, much discussed works, gaining avid fans not only in Japan but throughout Asia and the West. Karyu no miya (The Ocean Chronicles) won the Hayakawa Publishing “SF ga Yomitai!” Award for Best Japanese SF Novel in 2010, as well as the 32nd Japan SF Award and 10th Sense of Gender Award in 2011.

In the 25 century, much of the land was submerged due to an upheaval caused by a hot plume. Humans survived by adapting to new environments. Seafarers, who live in the ocean, live on giant biological ships called fish boats, and landers, who are based on land, have built an advanced information society based on a small amount of land and cities. In this new world, the protagonist of the game is diplomat Aozumi Seiji, who continues to negotiate for coexistence while adjusting various interests.
The theme of the game is Aozumi's way of life, as people live separated by global changes, and he searches for coexistence through dialogue with people from different walks of life. While adhering to his beliefs, he is conflicted about having to respond flexibly to the circumstances around him. He confronts people from different walks of life, sometimes facing situations that undermine his beliefs. Nevertheless, he does not give up and continues to engage in dialogue and find common ground.
Another attraction of the game is its detailed worldview. The realistic depiction of the social structure and technology of Earth in the future of the 25 century, the state of maritime cities, and the life of people living on limited land gives us the sense that we are actually walking in this world. In particular, the depiction of the fish boats is overwhelming, and the enormity and biological texture of the fish boats are conveyed realistically.
The story also reflects the challenges facing modern society, including environmental issues and social conflicts. One of the main attractions of this work is that it makes us think about how humankind will navigate the future and how diverse the options are.
When I read this work, I felt both hope and anxiety about the future. How people will cooperate with each other as the global environment changes and lifestyles change drastically. Although Ueda's world is far from optimistic, it still gives us a sense of human strength.
As you can see, this is one of the most profound works in recent years, combining a rich theme with attractive characters and a detailed worldview. While portraying the problems facing society in the future, it also appeals to the importance of hope and coexistence, and contains the message we need in this day and age. We can't wait to see what the next chapter will bring to Aozumi and his friends.
