Failures are an inevitable part of great inventions. The trick is to transform those failures into success! After all genius is 1% inspiration and 99% luck!


Gen (「ゲンナイ」?; Gennai) is proclaimed to be the best mechanic in all of Nippon[1]. He can be found at the top of the tower near the palace of Queen Himiko which can only be reached by using Catwalk to scale the side of the building in Ōkami, or using Vine to reach the tower's top in Ōkamiden.



Gen as he appears in Ōkamiden.

Gen is a short, elderly man who barely comes up to Amaterasu's head. One of Gen's most defining physical features is the large lightbulb that sits atop his head. His entire head, with the exception of his small, round nose, is covered by his messy white hair. He has large, teardrop shaped eyebrows that serve as the only indication as to where his eyes are. He wears a purple shirt with red and blue markings. His shirt is open, revealing his chest and the green necklace he wears. The sleeves on his shirt are long enough to cover his hands completely. In Ōkami he wears his shirt like a robe that drags along the ground as he walks, it appears as though he wears nothing beneath the robe. In Ōkamiden, his shirt is significantly shorter, ending at the waist. He now wears black pants, a yellow helmet and carries what looks like the Gimmick Gear on his back, to fit with the excavation of the Underground Ruins he has been conducting.


He is a very eccentric person and fits the mad scientist persona very well. He shows this in his inventions which are often too far-fetched to create. Issun points out that his current invention isn't even made properly. Although his inventions are not always even near working it is shown that when they do work, they work even better than expected. Gen is very much a person who never ceases to believe in learning more things in life and has gained a fascination with the technologies of the Moon Tribe[2] which have greatly influenced and helped him in his work. He also is somewhat obsessive when it comes to finding a new type of machine or technological wonder as he will immediately attempt to build said object even when he doesn't know what it does and more often than not fails in the attempt. However despite his numerous failures he is never discouraged and makes up for these constant setbacks and problems with a bright and cheery attitude until he succeeds or finds yet another mechanical device to work on, often returning later and finding success.

  • "My masterpiece is but one step away from completion. All I need is the final part! My invention would dramatically improve people's lives. It is the greatest test of my talents thus far!"
  • "All I need is a single Gimmick Gear! Without that single gear, my contraption will not move an inch. Must I once again roam these lands in search of the final part?"
  • "Oh, thank you, my fine furry friend! When my masterpiece is complete, I shall write your name in small letters near the end of my encyclopedia of contraptions!"



  • Gen is based on Hiraga Gennai, a Japanese inventor who lived in the 1800's. He is famous for his Elekiter which is an electrostatic generator. Gen's relation with electricity in Ōkami was derived from this.
  • Gen refers to Amaterasu as snowflake[5].

  2. 2.0 2.1 "I am quite the traveler and have seen much of Nippon, you know. And I have collected many strange odds and ends during my travels. Sculptures never seen before. Strange stones unlike any others. Such things have led me to believe that many ages ago Nippon was home to a completely different civilization from ours."—Gen (Ōkami)
  3. "Many a contraption have I built. City Checkpoint's Big Drawbridge, and Gojo Bridge here in Sei'an City... And now my masterpiece is but one tiny step away from completion."—Gen (Ōkami)
  4. "Did you see my masterpiece? It is a contraption for keeping time. I call it the money clock! After all, time is money! Never allow yourself to waste it!"—Gen (Ōkami)
  5. "I know not how you made it all the way up here, snowflake. It is unusual for me to have visitors. But your timing could not be better. I needed a break. Would you like to hear the new scientific theory I'm advocating?"—Gen (Ōkami)
