Why did the war with Japan make the Tsar unpopular?

The war with Japan (1904-1905) made the Tsar unpopular primarily due to Russia's unexpected military defeats, which exposed the weaknesses of the Russian Empire and its military leadership. The loss undermined national pride and fueled public discontent, as many believed the government had mismanaged the war effort. Additionally, the conflict exacerbated social and economic issues at home, leading to increased unrest and calls for reform, which further diminished support for Tsar Nicholas II.
