Location and accuracy Jap Creek, which is not named on the Wiseman B-1 topographic map, is a west tributary to Wiseman Creek. It joins Wiseman Creek about 1.5 miles northwest of Wiseman. The locations of placer prospects along the creek is uncertain and the prospects are arbitrarily placed about 0.2 mile above its mouth.
