Our original trip to Itsujima was cancelled, so we booked a trip to Saga instead, which was a pleasant surprise :D The attractions were less crowded, making it very comfortable to explore. We had just the right amount of time to spare, and we could choose to visit either the hot springs or the library. This time, we chose the hot springs. There were many pools to choose from, and the facilities were very new. Soaking in the hot springs was very relaxing, making it a very leisurely trip to Saga.
