More than half of Japanese honey comes from nectar from the locust tree, but the tree may be designated as a pest. The broadleaf trees originally came from North America, but it is very proligic and threatens the habitats of native trees.

The total Japanese honey harvest was estimated at 2,311 tons in 2004, but beekeepers are not amused by the possible designation, which is part of a larger move to designate pest species.
