On a windswept ridge at about 1,300 meters in Niihama, Ehime Prefecture, an extraordinary colony of Tsugazakura (Phyllodoce nipponica) marks the southern limit of this Japanese endemic alpine shrub. Designated a National Natural Monument in February 2019, the colony is a relict population dating back roughly 800,000 years to the Ice Age and holds outstanding phytogeographic, ecological, and genetic value. Hikers reach the site through the dramatic industrial heritage landscape of the historic Besshi Copper Mine, with the bell-shaped pink blossoms at their peak from mid-May to early June.

At the heart of Niihama City in Ehime Prefecture, the precincts of Ichinomiya Shrine shelter a National Natural Monument grove of around 90 ancient camphor trees.

Noshima Castle Ruins, set on two uninhabited islands in the Miyakubo Strait off Imabari City in Ehime, is the only sea castle of the medieval Murakami pirates designated as a National Historic Site of Japan.

Tucked away on a hilltop in Matsuyama City, Ehime Prefecture, Hasaike Kofun is an elongated oval burial mound built between the mid-6th and early 7th centuries. Designated a National Historic Site, it is exceptionally rare in Japan because two of its horizontal stone chambers were found completely undisturbed by ancient grave robbers. Discovered by chance in 1992 and investigated through five excavation campaigns, the tumulus has yielded extraordinary insights into late Kofun-period funerary rites, including physical evidence of the ancient practice of 'mogari.' Today, visitors to Hasaike Kofun Park can view Stone Chamber No. 1 up close and learn about ancient Japanese views of death and burial through the on-site guidance facility.
