The full name I use for professional and personal purposes is 'Jonathan Jenkins Ichikawa'. I added the 'Jenkins' upon marriage in 2011. I typically publish using all three names, although my older work appeared under 'Jonathan Ichikawa'. I don't care whether you include a middle name or initial when citing my work in your bibliography (whether or not I published the work in question with it).
'Jenkins' does not appear on my passport.
I consider 'Jenkins' to be my middle name. It is not part of a compound surname. Its inclusion is optional in all contexts, and it is subject to abbreviation. (Compare the 'Kellogg' in 'David Kellogg Lewis'.) I have prepared the following chart for the convenience of the public.

Please note that these lists are not exhaustive.
All of the above, mutatis mutandis, is also a pretty handy guide to Carrie Ichikawa Jenkins's name. (We were guided in part by the precedent set by Tamar Szabó Gendler and Zoltan Gendler Szabó.)
