Jobs with Diploma in Food production

I’m really thinking about diving into a culinary career and I’d love some advice about possibly moving to Japan in the future.

I’m looking to get a Diploma in Food Production, focusing on hotel management and culinary arts. I’ve been researching into visa options, but the information I am finding is mixed. It would be super helpful to hear from folks who have been through this.

Here are the main questions I have:
1.Is it feasible to obtain a work visa in Japan with just a diploma in food production, or do I typically need a bachelor’s degree?

1. I’ve come across info suggesting that some positions require around 10 years of experience if you don’t have a degree. Does that also apply to chef and hospitality roles?

2. How realistic is it to move to Japan through skill-based pathways like hospitality or food service?

3. If I focus on Indian cuisine,, will that boost my chances of landing a job in Japan??

5.What level of Japanese should I realistically aim for to get started in kitchen positions?

My current plan is to build my skills, gain some experience, and learn Japanese at the same time. I just want to figure out if this path is actually doable or if I should reconsider my options early on.

I would really appreciate honest insights.
