hostel in august

I was just wondering is it easy to get hostels in august if I don't book in advance? Meaning I could just walk in/ book 1 week in advance?

I'll be entering a languange school there, so I was planning to do some traveling in the weekends.

I'm alone and all I want is a place to sleep during my weekend travels, save me from numeroous day-trips :)

Thanks in advance for your replies!

It is very risky, especially in mid August and especially in popular tourist destinations.

I see... Thank you for the warning :)

How about transporation though? Would I be able to do unplanned day trips to various places with ease?

What I mean is... I'm based in Okazaki, Nagoya. Would I be able to get night bus/train tickets without bookings? Or is it too risky as well?

Pls read this first.

Since you are in Greater Nagoya, it wont be too crowded to do daytrips in the region during Obon, but I agree with Uji that you should not plan interregional travel to Tokyo or Kyoto/Osaka then.
