In Parts 1 and 2, we walked the mountain paths of Tanzan Shrine and learned how Fujiwara no Kamatari’s quiet planning here, 1,300 years ago, helped reshape the entire structure of Japanese government. But the story doesn’t end with Kamatari himself — it continues through his descendants, and it may still be living in your own family name today.
Over the centuries that followed, the Fujiwara clan grew into the most powerful aristocratic family in Japan. As the generations multiplied, branches of the family were sent out to govern provinces all across the country — and many of them took on new surnames that combined the name of their new region with a single character from “Fujiwara”: 藤 (fuji).
This is why so many common Japanese surnames end in “-tō” or “-dō”: Sato (佐藤), Ito (伊藤), Kato (加藤), Saito (斎藤), Ando (安藤), Endo (遠藤), Goto (後藤), and Kudo (工藤), among many others. According to long-held tradition, each of these names marks a family that once branched off from the Fujiwara line — and, by extension, traces back to the very hills we’ve been exploring this month.
Of course, not every “-tō” surname has a documented connection, and centuries of history make a single, certain answer impossible for most families. But it’s a thread worth pulling on. If your family name carries that 藤, somewhere in the deep past, your line may have a connection to the quiet shrine on this mountainside — and to the moment that changed Japan’s history.
This is exactly the kind of thread we love helping people follow. If your surname has “fuji” hidden inside it, or if you’ve ever wondered what your family name actually means, our Surname Report digs into the history and meaning behind it — and our Family Tree service can help you trace the line itself, generation by generation.
