Summer 2026 – Prague, Italy or Japan?

Hi all! My fiancee has given me three choices for our honeymoon in late July/early August next year. They all seem amazing, and I've been putting together itineraries and pro/con lists for each one, but I'm still struggling to pick! Any thoughts are appreciated. Here's what I would want to do in each place:

ITALY (florence, Tuscany and Cinque terre) – cooking class/food tour – Tuscany – wineries – Cinque terre – beach time and shopping – Apuan alps – Florence museums – duomo, uffizi, etc

JAPAN (Kyoto, Hakone and Tokyo) – 3 days in Kyoto, 2 in Hokone with onsens, 1 day in Tokyo – feed the deer (Nara) – hike Mt Fuji – Kirby cafe – torii Gates – tea ceremony – Japanese jazz bar

PRAGUE – hike Bohemian Switzerland national Park – cabin stay overnight – Jewish quarter – Prague Castle -astrononical clock – klementinum library – national gallery

Here are the pros and cons I've put together for each place (mostly pros):

JAPAN PRO – When else would we go, since it's so far away and intensive – aside from the flight it's relatively cheap rn because of the Yen

JAPAN CON – long distance – could be really hot and humid that time of year – more travel required (I've read that the shinkansen might be closed that time of year?)

ITALY PRO – best food – possibly most romantic, stereotypically – gluten without the consequences, supposedly (she's gluten intolerant, though not so much that it would be an issue) – beaches and mountains

ITALY CON – Hot, though not as humid as Japan – lack of a/c?

PRAGUE PRO – cheapest – closest/easiest flight – cooler weather in summer – possibly the most relaxing

PRAGUE CON – food doesn't seem as interesting as the other places

Any thoughts? Pros or cons we haven't thought of? Must see items that would sway the decision?
