Check the Japanese site for a ruling or wait for English Bushi.

It is unknown whether or not this effect activates at all in that situation. Other life saving cards either specifically say to activate whrn life reaches 0 or have counter and activate before the damage is dealt. If it does, you should survive with 1 life. I can only think of 1 other similar card and it doesn't have a ruling either.
