Can someone help me if there are multiple bus company that operates from Takayama to Shirakawago.This is not what you mean, I think,
but the highway bus section Takayama -- Shirakawa-go
is
jointly operated by five companies;
itfs a common section among bus routes connecting
Takayama City with Kanazawa City, Toyama City and Takaoka City.
unfortunately the seats were all sold out for february 23,2026. Some buses to depart from Takayama in the afternoon
seem to have vacant seats
for Takayama -> Shirakawa-go.
However,
buses for you to get back to Takayama in the evening
has almost no seat left.
The system says
the bus to depart from Shirakawa-go at 15:45
(and arrive at 16:35 at Takayama)
has one seat still available,
but the other buses departing at 14:45 or later have none.
Alternatively,
you can take a highway bus from
Nagoya to Shirakawa-go,
if your itinerary suits it.
For February the 23rd, there seem to be vacancy in some buses.

February the 23rd is a national holiday;
this year itfs a Monday.
During the extended weekend,
popular tourist sites may get crowded with people who live in Japan.
Itfs worth considering changing your dates, I suppose.
