Japanese crossword «Red shell for Curling»

Nice easy picture!

Good intro to coloured nonograms.

What in the world is it?

It's a curling stone from the sport curling: https://en.wikipedia.org/wiki/Curling

It's this weird sport where they have these big stones they slide on the ice towards a target, and then use a broom to sweep in front of it to guide the stone's path and speed without actually touching it.

OKAY... Since when is a stone a shell?

Interesting that the previous comment (question) appears to be from the author of the puzzle.
On a curling stone, the handle is much smaller in relation to the stone.

Yes, that's weird. He really seems to be commenting (not defending) his only work.

The author probably did not fill in the English title, so it was automatically mis-translated, I think that's what happened. Par for the course though for someone who is always so judgmental about other people's work. This was not fun to solve or interesting at all.

I think maybe an iron?

Hah. I actually recognized it the minute I finished - and I'm not even Canadian (or Scots.) Just a fan of odd Olympic sports. Nice work!

seems a little "flat" for a curling stone. that combined with the lack of difficulty left me less than thrilled. That said, it is still a decent puzzle for beginners, or those progressing to solving with no clues, hints or conformations.
