"Vulture Journals"
In Japan, the term for "predatory journal" is "vulture journal", which is perhaps an insult to vultures, as the birds have an important ecological role.
Predatory journals are especially a concern when sincere but naive scholars publish their work in them, without the benefit of effective review, editing and distribution. There are many genuine low-cost journals that scholars can turn to if they are serious about their research.
On 19th January 2019, the Mainichi Newspaper in Japan published the following article (in Japanese):
Kyoto University urges people to refrain from submitting to inferior (vulture) academic journals

On 27th October 2021, a further article was published about a Ministry of Education survey the extent to which public and private universities have warned their staff and students not to send their work to vulture publishers:
Less than 30% of private universities respond to the problem of vulture journals while 80% of national universities do respond, according to a survey by Ministry of Education, Culture, Sports, Science and Technology
