2 week April itinerary, First trip to Japan

Here’s my itinerary for mine and my wife’s first trip to Japan! Roughly 2 weeks from April 2nd-14th.

2nd: Arrive approximately 5pm to Haneda. Get to accommodation in Asakusa. Find dinner.

3rd: DisneySea. Random exploration after

4th: Ghibli museum? Then Shibuya

5th: teamlabs Planets. Senso-Ji then Ueno

6th: Shinkansen -> Osaka. Maybe teamlabs botanical garden

7th: Wander Osaka

8th: Nara? (Need ideas)

9th: Osaka -> Kyoto.

10th, 11th, 12th: Various shrines, temples and teamlabs biovortex on one of the days.

13th: Kyoto -> Kamakura

14th: Store luggage at hotel after check out and explore Kamakura then flight home in late afternoon.

As of now we only have our accommodations booked. We are planning pretty relaxed exploring whatever interests us in the moment with maybe 1-2 specific areas we want to hit each day. Is this good or bad for a first trip? Would it be better to have a more specific planned out itinerary?

Is Nara or an extra day in Osaka more worth it to you?

My wife (20F) and I (22F) are definitely more interested in nature and shrines than nightlife/izakaya vibes.

Please give any insights to how navigate Japan with the expected crowds during Sakura season!

Thanks for any advice or suggestions you give!

PS: have been wanting to go to Ghibli museum but just yesterday saw something about having trouble getting tickets? What’s that about?
