As far as I know the Kômyô Shingon is part of the daily service in all groups of the Shingon Shû.
My understanding is, that Mikkyô is characterized by the use of Mudra , Mantra and visualisation. I know the Kômyô Mantra, but what about the Mudra? Do you hold your hands simply in Gassho? And what I would like to know most of all is, if there is also some kind of visualisation involved. What do you think about while reciting?
I'm grateful for all answers.
Thank you.

Until you are taught otherwise and only after finishing Shido Kegyo, yes, use gassho.
There is most certainly a visualization for this, and it is taught along with the mudra, and much more besides.
Shingon has to be learned in prescribed stages. You have to walk before you can run. Mudras outside of their context within the full transmission lineage are basically meaningless finger exercises.
There is a basic meditation and analysis of the functions of this mantra in my forthcoming
Shingon Buddhist Service Book, to be published next month by Kongobuji.
