On February 10th, the Aoki Lake Fisheries Association conducted an investigation and concluded that the fishing season will not be lifted this year. This year, there has been a lot of snowfall, and water has come out between the snow and ice. The temperature is expected to rise in the next few days, so the ice will melt due to the water, and the ice strength will not be maintained. You can look forward to boat fishing for smelts at Lake Nakatsuna in the green season. The green season Aoki Lake/Lake Nakatsuna smelt boat fishing, tempura, and day camp includes a tempura set rental, so it is a recommended plan for those who want to enjoy smelt fishing and tempura casually! The opening of the winter fishing season for smelt holes at Lake Nakatsuna depends on the weather and smelt resources. It was not lifted in 2025, 2024, or 2023. It was lifted in 2022, but not in 2021. This area is a cold region with a lot of snowfall. When there is a lot of snowfall, the snow acts as a cold protection and true ice does not form. Snow and ice form, but they cannot support the weight of a person. The hours for hole fishing at Lake Nakatsuna are 7:00-16:00 (2026 dates are yet to be determined). There are two sets available: Winter Lake Nakatsuna Smelt Hole Fishing Set + Tempura Set Rental and Winter Lake Nakatsuna Smelt Hole Fishing Set. The Winter Lake Nakatsuna Smelt Hole Fishing Set + Tempura Set Rental includes a tempura set rental, so it is a recommended plan for those who want to casually enjoy smelt fishing and tempura! Even beginners can participate with peace of mind in the guided course. Available periods are 4/25-5/15, 9/10-10/25. If you would like a guided course, please contact us in advance to apply.
