Suntory Whiskey Tour Dates

I wanted to know if the Suntory Whiskey Tours are only open from October thru March. I have a trip in May and wanted to see if I can do the tour.

If you are talking about the Yamazaki Distillery tours, they seem to be open every day except year-end/New Years Days and other days when the distillery itself is closed.

However, they seem to hold lottery for who can join the tours - for example, for March tours, they accept applications from January 15 to 21, the results to be announced n the 25th.

This is the page (in Japanese) for English language tours (you need to install an app on your phone to get the audio guide):
