Hi,you seems to be interested in the blog

 

The odd roof is  not a tunnel.

It's snow shed

The caption says the snowshed was built

continuously Daishaka tunnel. 

 

Kindly regards,

hmm I had a suspicious that this photo had to be toward the north side of japan and seem I was right when I looked up where Daishaka was

(well...the extra headlight sorta suggested it too! )
