hi everyone! i'm going to Japan (Tokyo, Osaka, Kyoto) in July! Any must do attractions/restaurants you recommend for each city?

Climb Mount Fuji and visit a snow monkey reserve.

https://www.japan-guide.com/
Great website and lists top attractions in each city. I used it extensively to plan my trip to Japan last fall (and again this coming fall).
Highlight for me was Arashiyama in Kyoto. An absolute must. Take the hike up the mountain to see the monkeys; it's worth it for the view alone.

Well hello there!

Some great (and generally under the radar) places in Tokyo - Ebisu Yokocho, TRACK Ebisu, Seibu Rooftop Beer Garden (Ikebukero), Aoyama Flower Market Tea House (Omotesando), Lion Cafe (Shibuya). There are also festivals (matsuris) happening ALL MONTH all over the city - they're always a good time. Check Tokyo Weekender (blog) to see what's going on.
Kyoto - If you have time, I'd highly recommend taking the tram out to Kibune for an afternoon to try out a traditional kawadoko restaurant. Otherwise, if you need a place to chill between all the temple viewing, Cafe Bibliotic Hello! is a cute little cafe
Enjoy your trip!!

Oh! And depending when you're going the Sumida River Fireworks Festival is equal parts super fun and mindblowing. I usually don't care for fireworks but it was seriously next level stuff haha. https://www.kyuhoshi.com/japan-summer-festivals-calendar/

I second Ebisu Yokocho. Someone brought us there. From the outside it’s unassuming. We never would have thought it was an alley fully of places to eat and drink. We really enjoyed it!

This was the best meal I’ve ever had!

If you have the $$$ stay at an onsen Japanese spa where you can experience Japanese hot spring bathing, gourmet cuisine and a wonderful nights sleep!

do you know approximately how much that is?

Gina they range in prices and change depending on the time of year. We stayed in one mid May. We paid approx $600 (cad) for one night! A friend of mine stayed in a luxury one at $1000/ngt. But there are places that are half of what I paid. It depends on what you’re looking for and how many stars you want.
We booked ours on a website called JAPANICAN

You can also visit an onsen for a couple hours if staying overnight isn’t within your budget (usually for entrance and towel rental it’s 1000 yen tops/$10 CAD!) About an hour outside Tokyo is a town called Hakone. Tons of onsens and things to do and on a clear day you can see Fuji !

Kyoto. Visit the train station. Go all the way to the top floor, terraces.

Basements of department stores..awesome selections of food

I'd also recommend getting out to the countryside.

Here are lots of good recommendations:

Shimokitazawa(hip neighbourhood. great shopping), and Yanaka (old Tokyo vibes) neighbourhoods in Tokyo. Way less touristy, give you a better sense of what living in Tokyo is like.

Lots to do in Tokyo - tiny bars in Golden Gai, awesome shopping, department stores and boulangeries everywhere (don't forget to claim your VAT refund if shopping), try going to a cat café. In Kyoto, go to Pontocho Alley, ride bikes through Gion during the day if you're short on time, Geisha dinner (book in advance!), and I second the onsen! Also, brush up on Japanese etiquette! They are very proper there. Eg. no eating or talking on phones on the subway, no smoking outdoors, paying etiquette, trying on clothes in fitting room etc. Their style is dressy especially in Tokyo where men are in suits and women sometimes look like they're walking in a fashion show. Awesome and inspiring! Have fun!

Chabuton in Osaka one of the best ramens I ever had

Bar Ben Fiddich. Bring your wallet.

I would say the Osaka Aquarium Kaiyukan is worth a visit.

Take the Rickshaw at the JR station in Kyoto through the bamboo forest and to to a few temples.. We enjoyed it

All you can eat KFC in tokyo!

If you can, catch a baseball game in Osaka. I was there in April it was great! Kyoto is beautiful. I did the urban adventures walking tour and it was definitely worth the $$

Oedo onsen and Tokyo sky tree mall !

Nara ! It’s about an hour away from Kyoto. The train to get there goes by fushimi Inari (1000 tori gates)so what we did was go there first for a bit and explore and then headed to Nara! Todai-ji temple is beautiful and has the country’s largest Buddha statue. There’s a bunch of deer that live there too which is cute !(just don’t give them food they can be a bit aggressive
)

Spend a night at Ekoin Monastery in Koya-san, which is a couple of hours from Osaka.

Tokyo: check out the main fish market (largest in the world and out of this world), check out some high quality and authentic kabuki theatre.

in osaka, climb mount tenpo.

Osaka:
Toki sushi was AMAZING!

There are a lot of sushi restaurants inside of fish market (Jyonai). I recommend you to go there to get an authentic Japanese sushi called Okame( there are one in outside of fish market, the other is inside of it which I recommend ). You will see many tourists wait over two hours to get in particular two restaurants near Okame. For me, There are all same good quality. Then there is Kabukiza( some people have recommended you already) it’s walking distance from Tsukiji fish market. Then you will see Ginza area( high quality area)
Also, you can go to Asakusa by subway to see Senso temple(Sensoji) and you can see Sky Tree from there. There are all pretty close.
