Kyoto/Tokyo 17 days does this itinerary look ok?

It looks very doable, I would even say that your 5 full days in Kyoto are fairly slow. I love Kyoto but that is a lot of Kyoto for me and I would consider a day trip to Nara.

Edited to add, you are missing Fushimi Inari, and that is easily combined with Uji (same train lines, Keihan or JR).

I agree it generally looks fine, but — for your nonnegotiable day trip to see flowers (and a temple in Narita apparently), you’re going to arrive in Tokyo the previous day, rent a car, find somewhere to park it overnight (where in Tokyo will you be staying?), then drive out of Tokyo for a very long day trip, back to Tokyo and return the car? I’ve been to Tokyo several times and trying to drive there is something I would never do. I would find some other way to get to the flower park, which I am sure is possible. Or if you must have a car, it might be easier to go by train direct to Narita airport, rent your car there and stay at a hotel nearby, then do your day trip the next day, return car at airport and proceed into Tokyo by public transit for the rest of your stay. Or maybe at least return the car at Narita to avoid having to drive back into the city.

It can be hard to get into dinner restaurants in Kyoto without a reservation. I might try for more than 4 temples a day. Are you going to Inari and Nara? Good break/different from Kyoto.

An alternative to Edo Open Air Museum is Nihon Minkaen which has historic buildings from all over Japan, not just Tokyo area. https://www.japan-guide.com/e/e3253.html

Disclaimer - I have not visited Edo Open Air Museum, but spent the better part of a day at Nihon Minkaen. There are some blogs and articles that compare the two if you search. I researched both at some point and, for myself, chose Nihon Minkaen. Your choice may be different! Actually, thanks for the reminder, I have another trip in a couple months that isn’t yet fully planned!

Arashiyama could take a full day if you really explore. There is, for instance, a preserved street area near Adashino Nenbutsuji temple. Google Sagano Toriimoto Preserved Street if you haven’t found it. There are a number of interesting small temples in that area. You could also explore to the east with Daikakuji, a large temple complex or to the south across the bridge.

It looks like you have found some of my favorite place in the west area. Retreating to Nijo Castle in the afternoon would also be a decent plan if you’ve seen enough.

I’m just thinking be flexible on that day in case you particularly enjoy Arashiyama. I enjoy that area when not over run with tourist crowds. Nijo Castle could be worked into a different Kyoto day - taxi transport is good to and from the castle for time saving.

I'm going to add one more suggestion in Tokyo that you may not have found, but seems to be within your areas of interest, The Old Asakura House. Taisho era house and garden that you can self-tour. It isn't really close to much else, but is a short walk from a couple stations. If you use Apple Maps to find your way to the entrance, you may be led to a parking lot toward the back of the property. Walk around the nearby corner and you will find the entrance.

Not a must-see for most I suspect, but for anyone interested in traditional architecture, very interesting.

With so many days, I think you could fit in more locations and it still be a leisurely trip. I would recommend spending two nights in a town like Kawaguchi or Hakone to get spectacular views of Mt. Fuji. I stayed in Kawaguchi and it was amazing. I would recommend visiting the sake brewery and taking the tour. Kawaguchi can also be done as a day trip from Tokyo, but I liked not being rushed and there is definitely enough to do to fill your time.

From Kyoto, I would recommend spending a day in Nara. Everyone goes for the deer, but the town is lovely with beautiful temples. And you can’t forget the green tea mochi. Also maybe consider a day trip to Osaka, especially if you’re a foodie. As others have said, Kyoto is super popular so if you want to enjoy the popular shrines without a sworm of people, get there early…like 6:30am. I got to Fushimi Inari a bit before 7am and there were still lots of people. There will probably still be loads at night too. When you’re in Arashiyama, think about taking the Sagano Scenic railway ride and then the Hozugawa river cruise on the way back (or take the train roundtrip), such beautiful scenery! I also recommend the monkey park if for anything, the view is fantastic. But the monkeys are so cute!

I love your careful planning. I don’t have anything to add, except that I lived in Hitachi for 8 years and you don’t see it on a trip plan very often. Ha! It is on mine for next year for different reasons.

With respect, I disagree with Kristina regarding adding in more sites.

We all have different travel styles and many would agree with her in using the vacation days to see as much as possible. However, as many others have said, I am impressed by the careful planning from the OP. The trip as laid out is more "my style" - I am a "less is more" person.

That said, I agree that Nara should be considered if it hasn't been already. I tend to see it more frequently than Uji on a first trip itinerary, but it does look like the OP has considered Uji well. Nara does have a lot to offer beyond the deer park and is quite an easy day trip from Kyoto.

Looking for a quick suggestion, Nara could be a replacement for Kyoto day 5. Return by 5:30 PM for dinner is not hard, Imperial Palace is a spot many consider missable (perhaps not the OP!), the other temples slid into other slots - or (dare I say???) perhaps skipped. I have a major interest and a bit of background in Asian religions, temples, and art. I found that after a week Kyoto, I was getting all the temples mixed up. It can all be overwhelming on a first visit. Just a thought - nikanshenme has been researching - impressive!!!

What a detailed itinerary.

Looks great, but I want to add at least one place to visit in Tokyo: Kappabashi street. It's lined with kitchenware stores. Previously, the patrons were mostly restaurant owners, but now retail shops are open to tourists. I bought A LOT of awesome, Made in Japan cookware and gadgets. Many of these items made great souvenirs.

One comment...... When visiting Kiyomisu-dera, go absolutely first thing in the morning. We walked the street uphill to it while all the businesses were still closed. We got to the temple when it opened. Take your time exploring it, but do make time, while you're still largely alone, to walk up and up and up and up and up to the pagoda. It was there, in the early morning (so NOT a morning person here), listening to the birds sing the day awake, smelling the plants, hearing no man made noises, that I experienced a most profound sense of peace. It was definitely worth rising early.

I think we completed our visit there before 7:30 and went home for breakfast and showers.
