The Petra Zone

Using Japanese-English dictionaries, I looked up the two words in my stupid user name to see what they mean. I found "kaisho" but I didn't find "seichu", so I'm guessing "seichu" isn't a word.

"kaish�" means: dissolution, extinction, cancellation

Similar words:

kaish� = withdrawal, collection
kaish� = renovation, remodeling
kais� = renovation, remodeling
kais� = shipping, forwarding, transporting
kais� = recollection, reminiscence
kais� = seaweed
keish� = minor injury
keish� = honorific

seich� = growth (seich� suru = to grow up)
seisho = fair copy
seisho = Holy Bible
seishun = adolescence, youth
