I notice they have 2 wheelchairs available. I think the Daio farm is wheelchair accessible.

テラスは、出口の脇にテーブルが１つか２つあっただけで狭かったような記憶曖昧ですいません。ペット可能かは、確認してないです。

Hi. 1 As you have JR pass you can take express train from Shinjyuku st．and change to local train at matsumoto and get off at Hotaka st. You can get some infomation from tourist information center there.

Yes, it is open year round.

there are a few companies near the station who will rent you a bike for a few USD/hour, no booking required.

Taxis sit in front of Hotaka Station. When we were there, the information office at Daio were very happy to call a taxi to come and pick us up to get back to the station. Just a 15-minute wait but make sure you time it right for your train.

収穫体験はなかったと思います。他の方が書いてあるように、散策とワサビを使った物の食べ物とお土産位だったように、思います。ワンコ連れが多かったですよ。

They did not fully answer this question in detail during the tour....they are quite secretive about their methods. However they did mention that they cover the plants with nets in the winter and when we were there in the Summer they had shades over the plants. They also plant trees besides the Wasabi to provide natural shade and they control the flow of water that reaches the plants. Hope this helps.

This is probably really late, but it's really not possible solely on public transportation. I did try to make it to both in one day, but by the time I managed to reach matsumoto castle they were closed already, we left early morning as well.

I am sorry that I can not help. I myself can not ride a bicycle so I have never thought of cycling. I visited Daio by car. Please be advised to rent a car at the nearby car rental office. Your just input the telephone number of Daio to GPS, you will easily reach there. If you don't have an international driving licence, you can have it translated, the translation fee is not expensive. Hope you enjoy your trip.
