Japan itinerary and tips-any help appreciated

[CocoKoko123]

Have 10 night trip to Japan booked for spring next year.booking everything independently.have so far booked flights (to Haneda) and accommodation-have 4 nights in Tokyo,4 nights in Kyoto and then 2 nights in Tokyo.
Have an idea of the attractions we want to see (cherry blossom, my Fuji,including 1 day at Disneyland, a day trip to Nara from Kyoto and to the bamboo forest from kyoto).. there is no way we could fit in a day trip to Hiroshima in to such a short time is there? Also not sure if Osaka is worth a look given the sort time frame? We will have dc 9&12 with us.

My questions are are there any particular not to be missed attractions or restaurants etc (I am getting confused with how many shrines/temples there are and can't visit them all!)

Also I have heard there can be issues getting uk phones to work out there and have heard someone mention about getting a portable WiFi pack-does anyone have any advice on how to go about this?phone would be useful for WhatsApp calls/messages and looking up directions when out and about there.

Do I need to buy tickets over here in advance for attractions or just turn up?does anyone know the official link for the Ghibli museum as I've heard that needs booking online months in advance as books up quickly?

For transfers to/from airport am I best booking these in advance online (eg a taxi) or best getting a train when there?

Finally, for transport (mainly train/bullet train I guess) do I just buy tickets for this once there? I've heard mention of a rail pass....

Thanks in advance, any help appreciated

zee Re the jet lag we have an overnight flight arriving mid afternoon , I'm assuming we will be full of energy that first evening as our body clocks will be 9 hours behind at bedtime so we should be able to squeeze some things in that afternoon/eve.im assuming it will be the next morning that will be tricky to get up as our body clocks will still think it's the middle of the night.so probably want a not too manic second day.

We spent our first full day in Nara. It;s perfect for getting over jet lag. Everything is near everything else - no tricky navigating or long walks. It's really pretty. You can just stroll, dazed, and coo at giant carved gods, golden buddhas and stunning temples and shrines. Feed a few deer and head back to bed.
