Willer Bus to Osaka questions

Hi!

I'm planning on reserving early to get cheap bus tickets for Tokyo to Osaka in late November.

On the Willer website, the cheapest ones I can find is 3600 one way. Do you think this is already cheap? Or do you know of any other cheaper bus comapanies?

Also, if Willer is the cheapest one, is there any other way to book seats so that I get assigned a lower deck seat? I've read somewhere that online bookings get automatically an upper deck seat. I'm currently here in Tokyo, but I can't speak Japanese.

Thanks!

This is about as cheap as it gets. Anything below 5000 yen can be considered very cheap in my opinion.

There might be other companies with similarly low rates, but they don't have an English reservation interface.

thanks! yeah, i did think that this was already a good deal. :D

so is there a Willer counter (somewhere near kichijoji will be great) in central Tokyo where I can buy tickets in advance?

The website booking is okay but I read somewhere that you'll surely get and upper deck seat in the bus.

I'd really want a seat in the lower level so that's why I'm hesitating to book online.

Thanks!
