Want to leave Japan after arriving

Hey everybody, just looking for some advice here. I applied for some english teaching positions a couple months ago, and was very happy when I got hired and chose a company. I have family here in Japan and was so excited to meet them. In the last few weeks, I have gone from incredibly excited to experiencing overwhelming feelings of dread. I have just gone through a very traumatic and depressing issue back at home. I accepted the english teaching position before this event happened to me. Because of my worsening mental health, I had wanted to cancel my move to Japan before I had even gone, but reluctantly, I flew in yesterday and am here now. I haven�ft even started my job, and I already can feel that there was no way that I was mentally prepared to make this change. I feel like I need to go back home and work on myself before I consider anything like this, and I truly regret not listening to my intuition beforehand. I�fm supposed to be here for a year, yet its been a day and I already feel like I need to go back. I�fm not looking for sympathy, just advice on how I can go back home simply. I haven�ft registered with the bank or health insurance or anything big like that yet, I only have my resident card, so I want to know what I need to do to go back. Money is not an issue for me either. I haven�ft signed a contract with my job either, was supposed to start next Monday. I just really need to get home and go to therapy.

Buy a plane ticket. Get on plane. Simple.

Sorry to hear about your health.
As a courtesy, I suggest you meet with the school & explain the situation & your desire to return home.
When recovered & if you wish to reapply, you�fre at least in their good books.
I wish you well.

Sorry to hear things had to happen to you the way they did.
If you want to leave, yes, I agree with the above poster, go talk to the school/employer once, tell them your situation, and make arrangements and leave.

As you got your residence card you�fll need to give that back when leaving. If you already registered at the municipality , deregister.

And yes, speak to the school to explain.

If you�fve got an apartment or anything else you�fll obviously need to cancel that contract too.

I don't know your situation exactly, (I can only assess based on the information you provided, obviously) but why not give it a try by staying for a few more weeks, to see if you feel any better? If you live in a big city, I'm sure there are local support groups specifically geared towards foreigners and expats.
