ralphmcox, this is Japan, however, I think it might be best to rope in our Japan guru, Philatarium to help you with more proper id as I don't think this is listed in the Scott Catalog. This may be a revenue of some type.
Here is a very similar revenue stamp from Japan noted in the Forbin catalogue. The design is similar except that your stamp does not designate any type of denomination so I am guessing it is for some other purpose. The cancellation on your stamp is similar to a telegraph cancel.
ralphmcox, the best answer I can give you is that this is, "The cancel is from the pre-World War II Ministry of Trade and Industry, and it is a revenue stamp." While there are design differences between the the stamp I have identified in the Forbin catalogue and your stamp, in the end it is a Japanese tax revenue stamp. My sources do not indicate a value but it might be worth watching eBay listings to get a sense of it's possible sold value. I see a lot of Japanese revenue stamps being sold on that platform.
