1, The single-sided leaf reed in Kokufu (around Gochi, Kokufu-betsuin, Kotagahama, Joetsu) There are colonies of a single-sided leaf reed around Kotagahama and also his first thatched hut (Takenouchino-Soan in Kokubunji- temple).  When Shinran left Echigo and moved toward Kanto, it is said that all the reeds joined their leaves in prayer.  2, Strung out Kaya in Tagami (Ryougen-ji -temple, Tagami, Tagami-cho) When Shinran was invited to preach a sermon at Gomadouzan, the master served baked Kaya seed. He planted one of the seeds and preached  about the Buddha’s providence, then the seed bore fruit. Moreover, the fruits had marks of being connected with thread, and some of leaves  were lined up in front and back alternately. This Kaya was then transplanted from Gomadouzan to Genjo-ji temple 600 years ago. Now it is  designated as a natural treasure. 3,  The eight clustered Ume plum (Baigo-ji temple, Kojima, Agano-shi) When Shinran stayed at this place, he preached a sermon and planted an Umeboshi seed. Then this seed put out a shoot and grew thick.  The bloom is light pink and eightfold and bears eight fruits in one flower. April and May are the high season of the blossom. 4, The Jyuzukake-sakura of Kojima (Baigo-ji temple, Kojima, Agano-shi) After staying in Kojima, Shinran put his jyuzu (prayer beads) on a Sakura tree and preached a sermon. Then the blossom dangled like jyuzu.  This Sakura is rare, so it is designated as a natural treasure. The high season is in early May. 5, The chestnuts bearing fruit three times at Yasuda (Koujun-ji temple, Yasuda, Agano) When Shinran was propagating Nembutsu at Yasuda, a believer presented baked chestnut and Shinran planted it. Then it sprouted and grew  thick. It bore fruit three times a year or one leaf spread and grew into two leaves.  The tree died but the offspring are growing and bearing  fruits three times. 6, The upside-down bamboo in Toyano (Saihou-ji temple, Toyano, chuo-ku Niigata) When Shinran was propagating Nembutsu at Toyano, he stuck a bamboo stick upside-down and preach a sermon. Then it grew and the leaves  thrived downward and made a bamboo grove. The bamboo was designated as a natural treasure in Taisyou 11 (1922). 7,  The grilled carp in Yamada (Tashiro-ke, nishi-ku, Niigata-shi/Saikyou-ji temple, Kounanku, Niigata-shi) When Shinran was leaving Toyano after being pardoned, he had a banquet with his believers. One of his believers presented a grilled carp and  Shinran released it in a pond in Sanno-shrine. The fish revived and started swimming.  A tree Shinran used as a clotheshorse later broke because  of a strong wind, people found images of Shinran and the carp appear in the surface of the broken brunch. 
The seven wonders of Echigo
The founder of shin Buddhism, Shinran walked around Echigo for his missionary work after he was exiled by the imperial court.  Many stories about the wonders Shinran made are handed down orally and you can see them in familiar plants and fruits now.  From these stories, we can imagine the gratitude and respect of people for Shinran at that time.
