By far the most powerful opposition to the realization of Oda’s goal of a unified country was that put forward by the Ishiyama Honganji, the chief temple of the Honganji branch of True Pure Land Buddhism (Jodo Shinshu). The Ishiyama Honganji was the apex of a huge organization of monto. and it was also the hub of the anti-Nobunaga league that was made up of a number of Buddhist institutions, daimyo, and eventually the shogun Ashikaga Toshiaki. In order to unify the country Oda Nobunaga had to reduce the power of the Buddhist institutions.
It is a book which have some information about Oda Nabunaga’s opinion about Buddhism.

It doesn’t mentioned anything about why Oda Nabunaga hate Buddhism. But it mentioned something about the result.

Nobunaga would commit a good portion of his military career to destroying the Buddhist fanatics. Now the Ikko-Ikki had been very troubling to Nobunaga. Through force they restricted his movements, not allowing him to gain control of Japan, as he wanted. The rebels also used economical warfare to battle Nobunaga, such as withholding tax and rent. They had also turned their temples into self-sufficient towns, concentrating them in all the places Nobunaga needed to control. Nobunaga so infuriated by the Ikko-Ikki vowed to eradicate them. Or as Nobunaga wrote he would fight Yama yama, tani tani “on every mountain and in every valley”.
