Hello. On our day in Arashiyama, we want to see the following:

Otagi Nenbusto (8 am open)
Adashino Nenbutso temple (9 am open)
Preserved street
Hozu River Boat Ride
Togetsukyo Bridge

How is it best to organize our day? If we take taxi from train station, to Otagi Nenbutso for 8 am open, can we walk to Adashino for 9 am open? Where next? thanks all

1. Otagi Nenbusto (8 am open)
2. Adashino Nenbutso temple (9 am open)
3. Preserved street
4. Togetsukyo Bridge
5. Hozu River Boat Ride

If you haven't taken the Sagano Romantic Train, you can take it from around the end of Bamboo forest to Torroko Kameoka.

Then take a train to JR Kameoka for the HOzugawa River Boat.

My favorite course is...,
1. Bamboo forest

2. Sagano Romantic Train (from Arashiyama to Kameoka)
https://www.sagano-kanko.co.jp/en/
* Be aware that this is seasonal and it will be fully booked soon.

3. Bus or Carriage to the the departure point of Hozu River Boat Ride

* Carriage might be fun bat you may need to wait long.
I gave up it for the waiting interval.

4. Hozu River Boat Ride

* If you cannot get a ticket or it is cancelled due to the climate, you can go back to Arashiyama by JR.

5. Togetsukyo Bridge

6. Monkey park

@H, how will I get from preserved street to bridge to river cruise? going with my 22 year old daughter so think train ride and boat will take up too much time. would prefer boat...

will monkeys be active late may? was not planning on monkey park for that reason.

thanks all

JR train Saga-Arashiyama to Kameoka. Same station you originally arrived at.

Boat and bridge are interchangeable as the point finish location is near the bridge.

I doubt you'll have time for the monkey park since you are doing the far flung temples.

so would these 2 temples, preserved street and boat ride, along with lunch, fill a whole day?

Let's really over estimate times needed including walking. Starting at 8am at 1st temple.

1st temple 1hr
2nd temple 1hr
Street 1hr
Lunch 1hr
Train 1hr (25mins Saga-Arashiyama to Kameoka)
Boat 2hrs
Bridge 1hr (15mins at bridge, more for surrounding area?)

Your order looks fine. You can see the bridge before or after the Hozugawa River cruise. It's always there 24/7 though, so you might as well make it last.
Timewise, unless your pace is very slow, or you really want to get into the shopping at the preserved street, you could likely fit more places there into the day. I don't know where you got the spelling of Otagi or Adashino "Nenbusto" - it's "Nenbutsuji". Anyone who went there can tell you that easily enough - but neither place takes that long. You also might like the bamboo grove at the back of Adashino Nenbutsuji - it's much less known than the Sagano Bamboo Grove, so not many people.

The river cruise takes the longest - a couple of hours. As mentioned, you could pair it with the Sagano train.
One other place you could add is Gioji, especially from late spring to the end of autumn - the moss garden is wonderful. Tenryuji is also very good - you can just pay to see the garden if you wish.

@Ken. Sorry for my horrible spelling! the bamboo grove at the back of Adashino Nenbutsuji is on my list. Gioji was not so thanks for recommendation. where would that fit in my itnerary please?

It's easy to see if you look at a map like Google Maps - it is in between the bridge and Adashino Nenbutsuji, just a bit over half a kilometer away and no detour needed.
You could also in the end walk through the Sagano grove + Nonomiya Shrine and also see the Kimono forest at the very end if you like - they don't close, and most of the mobs of tourists have left the grove by evening.
