If you had impeccable nature energy control you could have tiny amounts of chakra and still use Sage Mode. Lorenzo.r.1st wrote: hagoromo (in the filler) sensed it without gama telling him that it was there at all People have to be taught to sense it, but we don't know if Toad Oil is the only way to sense it. Juugo's KKG suggests that other means exist. So it's possible that people can learn to sense it in other ways. I doubt he was naturally able to sense it (since that would be a world first). Lorenzo.r.1st wrote: maybe hashirama had so much chakra that he sensed it and learned it by himself I think it's pretty much a given by now that he learned it by himself (since he lacks "Sage Eyes"). I think he simply found evidence of Nature Energy somehow (e.g. Juugo's clan) and figured it out himself.
