Bipalium nobile is a land planarian of the subfamily Bipaliinae found in Japan.

Bipalium nobile is a very long planarian, reaching up to 1 m (3.3 ft) in length.

As in other species of Bipalium, the head is expanded, being fan-shaped in live animals.

As it was not reported in previous surveys in the area, it is assumed to be introduced from elsewhere.

[1] Studies on regeneration have shown that B. nobile has a great regenerative ability similar to that of freshwater planarians.
