You can visit the oldest sake brewery in Japan, but don't expect to see much more than the outside. They don't do tours and won't let you taste. Its a real bummer! You can buy their sake there, but really, what's the point. Save your time and just go to a sake store.
If you feel compelled to go, take the train to Tomobe Station and from there its a 10 minute drive.
