If you could post that here, that would be great. Thanks
Here is their official website (I think the white dude is also in the FB photos): http://www.satsuma.ne.jp/daikoku/
The "ordination certificate" he is holding, as most likely all of those given by this 'master', is on folded wax construction paper. I am pretty sure the master does not have actual acarya abhiseka from any Shingon lineage holder, but just proclaimed himself an authority. This could be wrong however as here he claims some sort of initiation: http://www.satsuma.ne.jp/daikoku/sub20.htm
But in Japan, 16 year old girls, in groups of over 100 can get this sort of acarya initiation so long as they have the money and family connections, so even if he did get this ordination (the 100 day retreat ordination) its not that big a deal actually.
I attended one of their rituals. It was....bizarre. One of the attendees (an initiated priest) was possessed by a monkey spirit. He would jitter and shift, make insane sounds, etc. When the "master" would point his shingon wooden wand at him, the priest would then begin to choke, cough and came close to fake vomiting.
For the life of me, I did not see why, as an outsider they were attempting to recruit, they would let me see this display. The "posessed" dude with the monkey spirit, between fits, would make sure I was watching him and when I was pointedly ignoring him (as it was just frikkin looney tunes) would then turn the volume up on both his insane sounds and spasms. The master would repeatedly take his wand, turn it away from the monkey-posessed guy, then turn it back pointing towards him, in order to prove that the power was real (as the insanity only transpired when the wand was being pointed towards him). This was all in a very informal setting.
I also know that the sect, not based in Koyasan (nor without any Koyasan affiliation...which they claim to have) in their rural headquarters in Japan, as part of their training have their disciples go walk around the forest and find rocks, which are then brought back to the master. The master then tells them which bodhisattva/buddha/deity lives inside the rock and with that, the disciple is granted some sort of special power which is housed within the rock. They then wrap the rock in lovely cloth and use it as a sort of spiritual "soap" and wash each other with it before and after rituals.
All of this, of course, is just their own weirdness and not anything found in mainstream Shingon. They are a shinsukyo, modern religious movement (aka cult). If you look through their pictures, you see the same 6-10 people in all the photos who travel around with the master and his wife (the bald lady next to him). They have branches in the UK, Italy and I have heard secondhand that they have a branch in the United States as well now.
There is more weirdness I could recount from my few interactions with them, such as the master showing me photos of Mahavairocana appearing (it just looked like cheap photoshop...not even done well) to him above the godawful ugly statues he carved (which Mahavairocana of course appeared to him and told him to carve). On this page: http://www.satsuma.ne.jp/daikoku/eibunn%20nyuugaganyuu.htm
it also says that Kukai appeared on the back of their master's head on some spcific day, and show pictures of it (I don't see Kukai there, just the back of his head, but anywho) and of course this expresses the deep meaning of Shingon doctrine (note the sarcasm).
