Cold run

These guys look really "cool" or just COLD??

I think most of these guys should pray for nicer bodies and less man-boobage. That would be "healthy" There's one near the back with a nice body though.

Those nappies are fundoshi ie traditional underwear. Quiet comfy actually.

Holding an cold endurance festival in summer, I miss something here. New year dipping into cold rivers /seas is also widespread overseas.

It's cold enough without being naked in a pool of ice water. I hope they had an ambulance standing by in case...

Ice cold water causes major shrinkage.

It is more than I can bear!

Maybe you mean "It's more than I can bare" LOL

I like those nappy-like pants.

Did something similar years ago up in the north of Honshu. In our case, however, it was a slow-moving procession down the streets of Morioka. I seem to remember that I lost all feeling in the extremities after about 5 minutes. The bath afterwards was great. Looking back, I suppose the sense of euphoria and fatigue were initial symptoms of hypothermia. Once was enough, thank you very much.

I thought the Japanese people are basically not religious (無宗教) but I see this is not true. Still Japan is a very religious nation.

It would be more sensible to hold these pants matsuris in summer, rather than risking pneumonia.
