Thanks for the nice words about my city ^^). Of course, if you have the opportunity, then visit Ukraine. Just keep in mind that Ukraine is very different depending on where you are going. There are four different types of Ukraine. North, West, South and East. Each of these parts has its own climate and traditions. I am from the East of Ukraine from a place called Donbass. As for the war with Russia, to be honest, only soldiers are at war, and from no one side no one touches peaceful people. So do not worry, because if you want to go, then no one will touch you. Foreigners are treated well. I in general adore Japan.
