Thank you for your understanding and cooperation in the educational and research activities of the Ashiu Forest Research Station.

Forest Entry Prohibition Period: Until Friday, April 18, 2025
Please note that depending on the progress of the work, the entry prohibition period may be extended. If an extension is necessary, we will send another email as soon as the decision is made.
