There's nothing new in this clip of Kaku being interviewed on MSNBC last year, but still it provides a good, short summarization of his views on the UFO phenomenon.

Scientists sometimes judge alien technology on the basis of what we can do, not on the basis of what a type three civilization, millions of years in advance of ours, can do.For "scientists", substitute "UFO researchers", and you'll see where the problem lies in UFO research, even as it applies to the extraterrestrial hypothesis.
In May, 2009, I was in England filming four episodes of the television series Ghost Cases. After we were done, my co-host Holly Stevens and I stayed on in Europe for three weeks on vacation (England, Scotland and the Czech Republic). While in London, I attended a lecture by Dr. Michio Kaku at the Royal Society for the encouragement of Arts, Manufactures and Commerce (RSA) on the 28th of May, and took the opportunity to ask him a question about his view that we might be in the midst of an intergalactic conversation, and not even know it. This short episode of The Other Side of Truth features that exchange.
