Will I be able to survive with only the knowledge of hiraganas and katakanas in Tokyo or somewhere else in Japan.
for example, does the roadsigns have everything written down in basic hiraganas or kanjis ?
ありがとう ございます in advance

If your spoken Japanese is good, then you'll be able to survive, but it's always a good idea to learn how to read kanji. My first time going to Japan was a few years ago and I could only read a handful of kanji, but since my spoken Japanese was good I was able to manage just fine. If anything just ask questions and you'll more than likely get the answers you want.
