Where to avoid during Golden Week

I will be travelling in Japan between April 24-May 6. Should I plan to be in Tokyo and Kyoto during Golden week, so that I can avoid the crowds and ghigh prices? Or does it not really matter that much?
thank you!

Kyoto will be crowded, especially between May 3 and 6, but prices barely differ from the rest of the year. Tokyo is not crowded and there are no price increases.

I recommend to avoid traveling on May 3 (especially out of Tokyo) and on May 6 (especially back into Tokyo). Some more details:

Thank you. I am planning my itenerary as follows, do you see any problems I may encounter? Any suggestions?

April 24: Arrive in Tokyo
April 25: Overnight in Tokyo
APril 26: Train to Kyoto
Apr 26-29: Kyoto
Apr 29: Train to Osaka
April 30: Day trip to Mt Koya
May 1: Train to Nara
May 1-3: Nara
May 3: Train to Tokyo
May 3-6: Stay in Tokyo
May 4 or 5: daytrip to Nikko

Nara is a quick trip from Kyoto, better to see it whilst there rather than backtracking.
