The battle of sekigahara wasn’t only about logistics imo:
- Kobayakawa had large forces on a hill for half the battle couldn’t decide which side until both sides pretty much not only threatened him but started shooting arrows on his troop well into the battle - he chose the Tokugawa side
- Other defectors like Kikkawa and Akaza late decided the battle as they followed Kobayakawa
- Mitsunari was charismatic and deeply loyal to the Toyotomi side but still had a of issues recruiting lords to fight for him
- Background: Toyotomi Hideyoshi passes away in 1598, and it creates a power vacuum. Ieyasu now in his late 50s is ready to take over (after seeing unification happen first with Nobunaga, and now with Hideyoshi, there’s finally an opportunity for him) but Hideyoshi’s son and his mother are in the way. This was the literal and metaphorical battle between the incumbent and the challenger 
- So every daimyo in Japan has a choice, stick w/ the old Toyotomi, or fight for the Ieyasu, or abstain. It was a bet
