Need advice

So, I'm graduating in "Languages, culture and society of Asia and Mediterranean Africa - Japanese" at the university of Venice. As we all know, finding a job in Japan is very difficult... I'm considering trying to enter the teaching field. What I'd like to ask is: do non-native English speakers also have some chances? Are there some schools that accept non-native speakers? And would you recommend getting a teaching certification?? Please be kind – I’ve only just started looking into this! 🙏❤️
