Replying to Questions about Japan.

I'm wanting to spend the 19-20 season in Hakuba.

How early should I arrive to secure a room, also how much would I look at paying a month?

What part of hakuba should I aim to live in, I won't have a car so somewhere near public transport is boss.

I should have about 6-10k nzd saved up, I assume this would would be enough to last the season, however how hard is it for me to pick up a part time job, provided I arrive at the right time, to supplement my income.

What resorts should I buy season passes for?

If you have any other info you think would be valuable, please do share.

Thanks!
