The Big Bento Box of Unuseless Japanese Inventions

I thoroughly enjoyed Kenji Kawakami's "unuseless Japanese invention" books, and now he has compiled all 200 "unuseless inventions" into one big book, dubbed The Big Bento Box of Unuseless Japanese Inventions, which you can easily buy at Amazon.com.

If you want to get a better idea of how stupid some of these ideas really are, check out this page which features 18 of the dumb concepts.


If you run into the Bumper Book of Unuseless Japanese Inventions, do not fear, for (as far as I can tell), it is the same as The Big Bento Box of Unuseless Japanese Inventions book. Fun.
