We found this bug in our house today. So far have not been able to identify it after past hour online. Its pincers look way larger than most normal beetles I can find. Can someone help us finger out more about this critter? Thank you enter image description here

  • $\begingroup$ It looks a lot like dorcus curvidens, but according to the wikipedia page, it's found in Japan. But I would lean heavily towards a dorcus species. $\endgroup$
