Travelling to Tokyo in March. Any feedback on itinerary will be appreciated

I will be travelling with my family to Tokyo from March 16th to March 22nd. I believe my itinerary is spread out enough to not feel rushed but please let me know if you think any day in particular seems packed. I heard March 20th is spring break so I am also concerned of places being extra crowded than usual. We will be staying in Shinjuku

March 17th - arrive in Narita and take bus to Shinjuku. Will spend first evening here and catch the sunset at the Tokyo Metropolitan building

March 18th - Ueno, National museum of nature and science, Ameyoko market, back to shibuya to catch sunset at shibuya sky

March 19th - Borderless, and Odaiba afterwards

March 20th (start of spring break) - walk through harajuku and into shibuya. Visit meiji while walking. Finish day back at shinjuku

March 21st - Asakusa, Senso ji temple, Akihabara and Ginza

March 22nd - prep to leave.

thanks
