There are three lineages of pratimoksha vows and none of them prohibits the eating of meat. Anyway, the transmission of the pratimoksha was lost in Japan, as attests the fact that the "monk" is married and lives with his wife.
He surely has the bodhisattva vows, however. There are also a number of lineages of bodhisattva vows. Some prohibit the eating of meat and some do not. For instance, in the Brahma Net Sutra, it says:
A disciple of the Buddha must not deliberately eat meat. He should not eat the flesh of any sentient being. The meat-eater forfeits the seed of Great Compassion, severs the seed of the Buddha Nature and causes [animals and transc endental] beings to avoid him.
The bodhisattva vows that I have (in Tibetan Buddhism) do not prohibit the eating of meat. Neither does it advise to restrain from eating meat.
Most Chinese, Japanese, Korean, Vietnamese have the bodhisattva vows from a lineage rooted in the Brahma Net Sutra, and therefore are encouraged to restrain from eating meat.
Even then, practitioners do not adhere that strictly to the bodhisattva vows.
