   We propose an ASCA observation of the high-ionization Seyfert 2 galaxy
   Tol 0109-383. It has been well-known that the optical emission line
   spectrum shows evidence for high ionization implied by [FeVII] and
   [FeX] which is unusual among Seyfert 2s. Our new optical spectroscopy
   shows spatially extended, high-ionization region traced by [FeX]. The
   photoionization model predicts a powerful X-ray ionizing source in this
   galaxy, but no hard X-ray observation has ever been done. To reveal the
   nature of the central source, X-ray spectroscopy at absorption-free
   energy band (above a few keV) is essential. The spectral capability of
   ASCA is the best tool to probe the central nucleus in this peculiar
   galaxy.
