Listed as a prefectural natural monument, the striking sight of the red torii gate at the foot of Shirahata Gingko Tree brings photographers and sightseers from up and down the eastern coast of Tohoku.It's also known as the 'upside-down gingko', owing to a legend that warlord Date Masamune planted a gingko whip upside down in the ground during an attack on Shinchi in the late 1500s. The best time to see the vibrant yellow leaves is usually the last week of November or first week of December.Although there is no parking lot specifically, there is space for cars to park on the green within sight of the tree.
Estimated to have been carved over 1,000 years ago, the Daihisan Stone Buddhas (大悲山の石仏) are a group of stone-carved Buddhas in Odaka, Minamisoma City, in the coastal area of Fukushima prefecture.The Daihisan Stone Buddhas are made up of three groups of statues: the Yakushido Buddhas (薬師堂石仏), the Amidado Buddha (阿弥陀堂石仏), and the Kannondo Buddha (観音堂石仏). The statues are enshrined in a forest area with many smaller Buddha statues.They are the biggest and oldest stone Buddha statues in the Tohoku area of Japan, and have been designated as a National Historical Site. Their origins, and much of their history, however, remain unknown, although they are presumed to have been built sometime during the Heian period of Japanese history, which goes from 794 to 1185.In front of the entrance to the Yakushido Buddhas is a 45 meter high cedar tree known as Daihisan’s Giant Japanese Cedar Tree. The tree has a circumference of 8.4 meters at eye level, and is one of the largest trees in Fukushima prefecture, also estimated to be over 1,000 years old. It is designated as a Natural Monument of Fukushima Prefecture.
Shiramizu Amidado Temple (Amitabha Hall) was constructed in 1160 by Princess Tokuhime of the Oushu Fujiwara clan, which built the "golden culture" in Oushu (the present Tohoku Region). It is the only building in Fukushima Prefecture that has been designated as a national treasure. Inside the hall stands a wooden statue of Amida Nyorai as well as a number of other Buddhist statues such as Kannon Bosatsu, Seishi Bosatsu, Jikoku Tenno, and Tamon Tenno.The garden, called Jodo Teien (Jodo, or "the pure land", is the Buddhist paradise) is a realm of natural beauty in every season. The scenery is especially breathtaking in summer when the lotus flowers are in bloom, prompting one famous writer to liken the garden to a mythical paradise.
Hozoji Temple is one of the oldest and most historically significant temples in the Soma region, known for its vivid autumn colours. According to tradition, it was founded in 801 AD by the military commander Sakanoue no Tamuramaro as a place to pray for success in his eastern campaigns.Although detailed records from its earliest centuries have largely been lost, the temple’s existence is attested in a few surviving documents from the 10th to 13th centuries, indicating its long-standing presence in the area. Over time, Hozoji Temple became closely tied to the spiritual life of the region and continued to develop through periods of reconstruction and renewal.The temple grounds are known for their natural beauty, especially the large fir trees - some over 400 years old - and numerous maple trees that grow throughout the property. These maples have long been admired for their striking autumn colors, and historical accounts suggest that generations of Soma clan lords once visited the temple to enjoy the seasonal foliage.In addition to its autumn scenery, the temple is also home to several varieties of cherry blossoms that bloom even during the colder months, offering visitors a chance to experience seasonal landscapes throughout the year.Architecturally, Hozoji Temple reflects the layers of its long history. The Niomon Gate, constructed in 1647 by Soma Yoshitane, the second-generation leader of the Soma clan, is one of the site’s most notable surviving structures.Today, Hozoji continues to attract visitors, photographers, and locals who come to enjoy both its historical atmosphere and its natural surroundings. In recent years, an evening illumination event held during the autumn foliage season has become a popular way to experience the temple’s grounds in a different light. The illuminations are typically held across one weekend in late November (for reference, the 2025 illuminations took place on the three-day weekend of 22-24 November.)
