Hi dude, if that you like is bold traditional japanese style, for me, two of the best and who have tattooed big part of my body are Rico and Shion of the Daruma Goya private studio in japan. They travel a lot around Europe, great balance about bold angry black background and great lines, you cannot wrong with this choice. @ricodaruma on instagram and DARUMA GOYA TATTOO, Japan
Other great options are @horitsukikage1 or @horimomo , and if you like more "westernized" style, @stewart_modernclassic is amazing.
Sorry for my english.
