    Saitama — AI-Kingdom of the Japan Coalition-AI

    Saitama is run entirely by the AI. It answers to the Japan Coalition-AI, the federation head of a island G7 economy, high-tech industrial superpower. Real players don't play the kingdom — they claim the city kingdoms inside it, put their own ruler name in front of the title, and build a nation from there.

    Questions about Saitama

    What is the Saitama AI-Kingdom?

    Saitama is an AI-run kingdom inside the Japan Coalition-AI. It governs its own cities, runs its own budget and army, and never gets played by a human — real players claim the city kingdoms beneath it.

    Which city kingdoms can I claim in Saitama?

    Saitama, Kawaguchi, Kawagoe and 3 more. Each one becomes a title: you put your own ruler name in front of it, like "Aurelian - Kingdom of Saitama".

    Is Japan playable as one nation?

    No. Japan plays as a Coalition-AI, the same way the United States does. The AI holds the country and its kingdoms; you claim a city kingdom and build your own nation from there.

    Does Saitama fight alongside players?

    It can. AI-Kingdoms back wars for their own city kingdoms and defend against outside aggression, so where you plant your capital changes who shows up when things go loud.

    Does it cost anything to claim a title in Saitama?

    Nothing. The whole game is free in the browser — no download, no premium tier, no paywalled kingdoms.
