• If your group includes children aged 0–12 please let us know in advance. • Akan-Mashu National Park is an off-the-beaten-track destination with few international visitors, so please be aware that guides may be less fluent in English than at busy tourist attractions. Please enjoy this secluded park, where 'omotenashi' Japanese hospitality more than makes up for any language barriers. Please understand that in booking this activity, we may share your booking information (but without individually identifiable data) to the Ministry of the Environment, with which this activity is affiliated. By making a booking, you signify that you agree to these terms.
