We must be careful not to bring alien species into Ogasawara or to disperse existing invasive species farther out in other islands or mountain areas.

Check your shoe soles for dirt and clothes and bags for seeds and small insects before getting on a boat or walking in the mountain areas.

To prevent the invasion of alien species to Hahajima Island, clean all dirt off your shoes before getting off the Hahajima Maru boat.
