From a book by Kyushin Kaku. Tabemasu successfully solved it on KGS when I showed it to him.

Ok, that limits it to three books I could find. What is the title? :)

Thank you so much for the nice problem, tchan. Your Japanese tsumego book seems beyond my level, but Black may be able to ruin the eye-shape from the inside with: B-S17, W-R17, B-S16, W-S18, B-S15, W-Q19, B-T18, and White can only make 1 eye.
