Positive: My stay at Sanyo-so is one I will remember for the rest of my life. A place carefully preserved over time, it's a ryokan with a story that has been maintained just as elegantly as the property itself. The staff are absolutely wonderful and you can tell there is a true respect for their roles and the caretaking of the ryokan. The rooms are more like having your own private home, with plentiful space, welcoming private gardens and onsens, and a feeling of peace throughout. The property's Japanese garden is truly exceptional and will remain one of the most beautiful gardens I have ever had the privilege of wandering. The kaiseki meals were astonishingly beautiful, with the chefs being incredibly meticulous over each and every dish- the standouts were certainly the melted cod in yuzu, the lily bulb tofu, and the simply marvelous breakfast bento. The restaurant space was designed in such a way that you feel as if you are dining privately, which added even more so to the phenomenal meals. Sanyo-so is a true sanctuary for those seeking a reconnection with nature, themselves, and an esteemed level of cultural remembrance which has been lost to the rest of the world.
Summary: An unforgettable stay
