We carried out spect roscopic observations of several supernovae with 1.01m telescope at Bisei Ast ronomical Observatory, inorder to investigate the type and characteristics soon after the discovery.Most of the observed supernovae were of type Ia.We present here some examples of the spectra and describe the necessity of the follow-up observation site in East Asia.
