Sanae Takaichi was elected due to anti-immigration sentiment, yet once in power she opened the floodgates to mass immigration. The Liberal State is not Ethno-Nationalist. It can only operate within a Liberal Framework. A new State will have to be formed. This is the case for all whom hope they can elect a Nationalist into power, the State has to be rebuilt. That is the hope with Trump, that he will re-create the State. Israel is the sole Ethno-State in existence at the current point in time, including their Left-wing and Right-wing as that is what the State was founded up. Besides re-creating the State, which is typically necessary for a radical and fast ideological transformation (Typical in Revolutions), you can also slowly re-form the State.
