My trip's itinerary:
Tokyo 22-25 Dec, will go to Mt Fuji & Hakone
Osaka 25 Dec-2 Jan, will go to KOBE & HIMEJI (1 Day); Nara & Stay 1 night in Kyoto.
Total : 11 people (1 elderly)
Can i check do you have any recommendation itinerary or sights to go?
It seems like you are going to travel a lot around Japan. Japan Rail Pass is worth it if you are traveling long distances and using Shinkansen (bullet trains). The one-way ticket of Shinkansen from Tokyo to Kyoto costs about 13,000 yen.
Strawberry picking usually open from January but "Grandberry" in Osaka seems to open in December. They don't say the specific opening date on their website yet. It's easy to access from central Osaka, 10 mins by car, and you need a reservation.
