pronouncing うproperly — is it closer to u or something else?

hi. I am from Azerbaijan, and trying to figure out if pronunciation of this kana is closer to "u" or "ı" in azerbaijani alphabet. Because while watching myself spelling it as "u", I see that my tongue height is mid, and in tofugu う corresponds to high height. And on other hand when pronouncing "ı" tongue's height stays high. Please help!
