Sennichite is repetition of move and position 3 or 4 times, I dont remember how many by present rules. Jishogi involves both sides getting their king into the opponent's area ie their own promotion zone. If both kings are safe from attacks and no loose capturable pieces remain outside the promotion zones, the pieces are counted up, 1 point each, 5 points for rook or bishop, 0 points for kings, if both sides have at least 24 (maybe 25?) points it's a draw.
