Jobs on a Working Holiday Visa?

Hello,
I am moving to Tokyo,Japan in July. Hoping to get my Working Holiday Visa.
I took 2 Japanese language class but I still aint very good.

What kind of job would be best suited?
I dont have confidence to teach English unless it was at a daycare or with little kids maybe.
Thinking maybe be a nanny. Dont mind taking care of kids. :)

I need a job to help me get by working in Japan til I can do well with my language.

I am a hairdresser. Would a salon take me?

Thanks.

Although your Japanese ability is very low bear in mind that most people who come to teach English in Japan have none or little Japanese ability and although it helps a lot when communicating with other staff etc. most schools will have you as an assistant with a Japanese teacher there during class and will want you to use only English (although this can vary). I would go for english teaching jobs as they are usually the easiest to get without Japanese ability and most do not require it- if they do they usually list it when advertising.

Thank you for your reply.

I dont really want to resort to teaching english because I do want to work on my Japanese but it might be a start to working in Japan. :)

Any places someone might recommend or companies to stay away from?
