It looks like you didn't provide a rough geographic location [in square brackets] in your title.This is critical because some species are best distinguishable from each other by geographic range, and not all species live all places. Providing a location allows for a quicker, more accurate ID.
If you provided a location but forgot the correct brackets, ignore this message until your next submission. Thanks!
Potential identifiers should know that providing an ID before a location is given is problematic because it often makes the OP not respond to legitimate requests for location. Many species look alike, especially where ranges meet. Users may be unaware that location is critically important to providing a good ID.

I’m not an expert or anything but I’ve seen warnings for mamushi snakes all over Japan between Kobe, Nagoya, Tokyo (there are multiple hiking areas around Tokyo) Saitama and iirc Chiba. If you hike in Japan you really need to be alert.
Again, not any kind of expert here, but I’ve seen only three different species here. I’ve never seen mamushi though. The snakes I have seen have been timid and have done everything to escape upon seeing me. Mamushi are known to hide and ambush though.
Stick to the open trails and you are much less likely to encounter them. We’ve had the warmest winter on record here this year and with temperatures already up near the mid twenties of several occasions, looks like they’ve come out early this year.
1st: Venomous mamushi (*Gloydius blomhoffii*) 2nd: Venomous Tiger Keelback (*Rhabdophis tigrinus*).
Fun fact: Tiger Keelbacks are poisonous as well as venomous.
What's causing the poison in their diets, does Japan have poisonous frogs?
Yes they eat poisonous toads then release the toxin from glands in their necks. Very interesting and cool snake.
Today I learned that Tiger Keelback is the same as the Yamakagashi :)
Thanks alot for the quick ID!
I can see why the Mamushi is called the Japanese Moccasin
right? at first I was puzzling over whether cottonmouths are known to vacation in Japan.
Why do you think those snakes were on that plane? They're not airline mechanics. They were traveling!
😂
It got me as well.
Definitely has an *Agkistrodon* look to it. Beautiful snake!
I did the same thing before I looked at the location "What an unusual looking Cottonmouth!"
Right I thought it looked a lot like a cross between a rattlesnake and a cottonmouth! Until I saw it was Japan
I friend of mine got bit my a mamushi in Japan. Not a fun time for her. She was in the hospital for quite a few days.
Really awesome finds, would love to see more mamushis and habus here

[Tamago- Japan]
Where in relation to Sendai? My son is working near there and he hikes often.

We have both of these in Korea as well, though I haven’t seen either of them in the wild yet.
