Thank you so much for these threads, which have helped enormously! We're going in July for 2 weeks. We booked flights back in March but only got round to booking accommodation this week. Family of 4, DCs aged 11 and 13 and it doesn't feel real that we're going!! DH has been once before, the rest of us have never been.
The plan is Tokyo (5 nights), Kyoto (3 nights coinciding with the float parade of Gion Matsuri), Miyajima Island (1 night), Hiroshima (1 night), Takayama (3 nights), 1 night back in Tokyo before an 8am flight and then 1 night in Hong Kong on the way home.
I've got lots of great recs on here - I'm going to download Wanderlog, sort out esims for everyone, and I'm going to book a cycle tour in Takayama to get out into the countryside which looks idyllic.
I priced up all the trains, and then compared them with a 2 week JR pass and it was much of a muchness so I've opted for the passes - then we'll also have the freedom to do any side trips, it covers the ferry to Miyajima etc. Quite a lot of train time eg. from Hiroshima to Takayama but I think we'll need the downtime and we all love long train journeys looking out the windows.
Now to figure out what to do with the 5 nights in Tokyo! We have no plans except to see friends for dinner at their house one night. I feel a bit overwhelmed as there is so much we could do and I know we won't even scratch the surface. Kyoto will mostly take care of itself with the big festival and one or two sights - I'm aware it'll be baking hot so I don't want to plan too much.
