karuizawa fruit picking in march

Hi, Friends,
Our family will be coming down from Nagano city and going towards Karuizawa for 2 night day on 24/3. We plan to stop-over at Komoro for some fruit picking activities before heading to Karuizawa Station where we have booked our hotel near there.
We need guide for direction to any farm house near Komoro or any farm house near Karuizawa that any friends can recommend here. We also need to know if we need to book in advance. Thank you.

Generally fruit picking season in Nagano is basically summer and autumn.
The very last one is apple, which starts around September and ends early December.
The next season is June for apricots and cherries. Unfortunately no fruits picking in late March as it is too early; average temperature in Karuizawa in March is 6.9c (max)/-5.1c (lowest), in April 13.9c (max)/0.3c (lowest).

But I've found one - strawberry picking (in greenhouse).
They are open from New Year's Day till the end of June.
