It seems that it was transmitted to Japan in the ancient Nara period via China and the Korean Peninsula. Emperor Nintoku of “Kojiki” (16th generation, Uji no Wakiiratsuko and the throne of the emperor Nukata Oonakatsuhiko who tried to seize the colonization of the emperor of ancient Japan Around the time (there are many stories that the peasants were willing to build this without building the palace, and the peasants were enriched by exempting the assignment of work), the song in which the radish appeared was sung. In the Edo period, it began to be cultivated in earnest and the number of varieties seems to have increased. Many varieties are still cultivated today, and this excellent agricultural product, which is the most widely available, has been mainstream since the 1970s. It is the most popular radish on the market and is characterized by its green neck. It weighs about 1 to 2 kg, is uniform in thickness, is elongated, and has a refreshing sweetness. Suitable for a wide range of cooking such as food cooked by boiling, pickles and salads.
Katori City has a place name called Japanese white radish: Oone (the origin of things). The upper part of the root of this radish is green. The roots turn green because chloroplasts are formed when exposed to sunlight. It can easily permeate CO2, but seems to be selective for other metabolites. The internal feature is that there is a network structure consisting of multiple folded membranes called thylakoid membranes, which is the process of decomposing NADPH (C21H29N7O17P3) and ATP synthesis (incorporated food using oxygen) in photosynthesis. It is a field for photodependent reactions (synthesis process by oxidative phosphorylation of generated energy, synthesis process in glycolysis without oxygen, process of converting light energy into photophosphorylation). The thylakoid membrane floats in the aqueous region of the chloroplast called the stroma. It seems to contain soluble oxygen that reduces carbon dioxide to sugar. The aqueous region in the thylakoid membrane is called the lumen, and the protons (same meaning as H3O+) that cross and are taken into the lumen seem to be the proton driving force for ATP synthesis. The thylakoid membrane forms a stack of folded vesicles called grana, or exists as a single layer of vesicles protruding and connected into the stroma. The thylakoid membrane region of grana that is not in contact with the stroma is called the granalalamella, and the region that is in contact with the stroma is called the stromalamella. The components involved in photosynthesis embedded in the membrane are specifically distributed in granala lamella and stroma lamella. By absorbing it, it captures the energy required for photosynthesis. The origin seems to be that a type of cyanobacteria (a group of bacteria that perform photosynthesis accompanied by oxygen evolution) coexisted intracellularly. It seems that it has its own nucleic acid called chloroplast DNA as a remnant of that.
Yamakura supreme being (daijin), which sits on a small hill, is a sacred place that has long supported the region during an infectious disease epidemic. It is said that the demon king of the sixth sky was solicited in 811 for the epidemic to disperse, and the king is enshrined. Until the Edo period, it seems that it was a Buddhist temple of Shingon Buddhism, Kanpukuji Temple. The Great Devil of the 6th Heaven was relocated to Kanpukuji Temple by Ordinance Distinguishing Shinto and Buddhism in the Meiji era, and was renamed to its current name in 1871. At the festival for the first Day of the Rabbit, which takes place every year on the first Sunday of December, salmon festivals and radish dances continue to this day, and locals cherish ancient legends and foundations.
