Something Like Musashi by Ejiji Yokinawa

I Read it today and I'm in dire need of a book that feels like Musashi by Eiji Yokinawa.

I do want to feel the intertwined lively characters that appear couple of hundred pages later to have a really important role to play, I want Well researched places to feel the journey, I want a Long book that will keep me on the edge the whole time, I want to see this style of writing or something similar, I want to feel the characters grow, I just need something as good as this book...
