Best way to get from Naoshima to Shodoshima?

Hi! I am hoping to visit both Naoshima and Shodoshima in June and debating what the best way is to get between the two islands.

I will be coming from Kyoto and am planning to take a train through Osaka to Okayama and then train to Uno to catch the Naoshima Ferry.

Is the best way to get from Naoshima to Shodoshima to go back to Uno Port and take the ferry via Teshima Island to Tomosho Port?

Would appreciate any guidance!! Thank you!!

You basically have three options, depending on what ports you want to depart and arrive.

Option one:
Miyanoura (Naoshima), Uno Port and then ferry to Tonosho from Uno (the one that also stops at Teshima).

Option two:
Honmura (Naoshima), Ieura (Teshima), and then ferry to Tonosho from Ieura (or from Karato if you want to visit parts of Teshima too)

Option three:
Naoshima, Takamatsu and from there you can go to Tonosho (Western Shodoshima), Ikeda (South) or Kusakabe (South East).

wow- thank you both so much for the helpful replies!
