The Jindai-zakura of Suzakura Shrine
Edo-higan Cherry (Prunus itosakura). about 1,200 years. Free, no ticket, shrine grounds open to the public like any Shinto shrine precinct. No parking at the site. Reached only by bus/taxi plus a real walk (see transport); a genuinely rural approach, not a doorstep visit.
