Unfortunately, it doesn't accept a count and won't work for Visual mode.
Maybe these mappings can help out:

" <Leader>j join without gap
" [count]<Leader>j and {Visual}<Leader>j

nn <expr> <Leader>j ':<C-U><BS>'
\. repeat('Ji <Esc>"_diw', v:count<=2 ? 1 : v:count-1)
xn <script> <Leader>j <Esc><SID>(NoGapJoin)

nn <expr> <SID>(NoGapJoin) (line(".")>line("'<") ? "'<" : "")
\. repeat('Ji <Esc>"_diw', max([line("'>")-line("'<"), 1]))

It needs quite a current Vim for the expression map to accept a count.

One remaining problem is: the dot command will repeat "_diw
