Kawaguchiko Retro and Omni Bus, same?

Hi,

I'm just a little confused about the buses for Kawaguchiko and the Fuji Hakone Pass

On the Fuji Hakone Pass page, on the "Free Area" section, it mentioned that "...Unlimited use.. of Fujikyu buses in the Fuji Five Lake region, including the retro buses around Lake Kawaguchiko"

And on the Fuji Five Lakes page, they mentioned about the Omni buses.

Are Omni and Retro buses referring to the same thing? And does the Fuji Hakone Pass cover the Red, Green and Blue lines referred to in the articles?

Thanks in advance,
Simon

Yes, they are the same. They used to be called retro buses, but over the years more and more normal buses were used instead of the retro-looking ones, and the name changed to Omni Bus.

Thanks so much for your response.

So just to be 100% clear for me, so the Fuji Hakone Pass does cover the retro/omni buses then, right?
