Here is a strange website in Japanese, which you can Google translate: https://ooyama-power.com/index.html
This site is rather amateur. It is bombastic such as where it says: "January 24, 2019 became a day engraved in the history of mankind." The author is Kazuo Oyama. (long O: Ōyama). I have never heard of him. The Google translation is okay, although confusing. The first sentence should be: On March 20, 2019 (Wednesday), company president Oyama will speak at the Japan Atomic Energy Society on "Metal Crystal Confinement Fusion Reactor" (described above). It definitely says "cold fusion." The author has renamed that "Metal Crystal Confinement Fusion" but he says this is better known as "cold fusion." The author has a paper on p. 55 here: http://jcfrs.org/file/jcf18-proceedings.pdf
