16 days i Japan – Itinerary check

Hi

My wife and I plan to go on our very first trip to Japan in march 2025. Arriving on 11th march, and returning on 27th march.

Start in Tokyo for 5 days (11-15 march).
– Akihabara (arcade, Claw machines, Nintendo)
– Kirby Cafe (Food)
– Tokyo Skytree
– Teamlabs Planets (special museum)
– Sensoji Temple (Tokyo oldest Buddhist temple)
– Shibuya Crossing (Crosswalk)
– Robot restaurant
– Lake Kawaguchiko (view of Mount Fuji)
– Omoide Yokocho
– Golden Gai

then to Kyoto for 4 days (16-19 march):
– Arashiyama Bamboo Grove (Come early)
– Arashiyama Monkey Park (wild monkeys)
– Nishiki Market (food marked)
– Fushimi Inari-taisha Shrine
– Pontocho Alley

then to Osaka for 6 days with 1 day in Nara and 1 day in Kobe (4 total in Osaka) (20-25 march):
– Dotonbori (neon lights, food, shops)
– Umeda Sky Building (night life view)
– Osaka Castle
– Universal Studios Japan
– Shinsaibashi (shopping district)

Nara
– Nara Park
– Todaji Temple

Kobe
– Kobe beef
– Rokko cable car

then back to Tokyo for 1 day (26-27 march) and fly back home at 27th march.

Will take the bullet train between cities.

Should I change the amounts of days each place ?
Is Kobe worth it ?
It does not seem a railpass makes sense according to the JR fare calculator.
Should we maybe take a day or 2 from the current plan and add another city like Hiroshima ?

Thanks fellow travellers
