First time traveler to Japan itinerary help?

I decided I would like to travel to Japan this upcoming February 13-28. 14 days of being in Japan not including the travel days.

I was seeing the best route for first time Japan visitors is going to Tokyo Kyoto and osaka.

Is there a general recommended day split for those cities.

I haven’t researched any locations yet so if there’s any good resources for an itinerary please point me to the right direction.

But if anyone can provide a general skeleton or guideline (day split,must sees, hotels) for this 2 week trip it would be greatly appreciated
