Hashirama's Sage Mode is most likely a Slug Sage Mode learned from the slugs in Shikkotsu Forest. Naruto has Toad, Kabuto has Snake, and there is one more place to learn it which is associated with slugs who are associated with healing and Hashirama has a third unknown sage mode and is known for great healing prowess and his granddaughter is also known as the "Slug Princess" and summons slugs. This all points to his Sage Mode coming from the Shikkotsu Forest for me. What else could it possibly be? The only logical conclusion is the Shikkotsu Forest.
