Wanna try Japanese pond smelt (=Wakasagi) fishing in the warmth of the houseboat?
You can experience it at Lake Nojiri, about an hour and a half drive from Shiga Kogen.
[FYI] If you use public transportation, it takes about 3 hours in total.
Shiga Kogen Prince Hotel – Nagano sta. (2 hours by express bus),
Nagano sta. – Kurohime sta. (30 min by Shinano Railway),
Kurohime sta. – Lake Nojiri (10 min by local bus)
