Kawasaki Frontale overcame a nervy finish to beat Jubilo Iwata 4-3 and give manager Yahiro Kazama his first win in charge on Thursday.
Kazama was handed the reins at the Kanagawa club late last month after predecessor Naoki Soma was fired after only five games of the season, but the former TV analyst endured a torrid debut in a 4-1 defeat to Sanfrecce Hiroshima last weekend.
Teenage midfielder Ryota Oshima gave his new boss hope of a happier afternoon at Todoroki Stadium, however, notching his first career goal in the 30th minute before two quick-fire strikes from Takuro Yajima and Yusuke Tanaka shortly after halftime put Frontale firmly in the driving seat.
