The Chiba Eco(Engineering Change Order)Agricultural Product Certification System was started in 2002 as an agricultural product certification system unique to Chiba Prefecture that considers environmental conservation and food safety and security. Chemically synthesized pesticides and chemical fertilizers are used less than half of the usual amount. In hydroponics, only chemically synthesized pesticides are said to be less than half of the usual amount. The producers of "Chiba Eco Agricultural Products" carefully record their work, such as "what pesticides were used and when." In addition, two inspections are conducted before cultivation and before harvest. "Chiba Eco Agricultural Products" starts cultivating after planning the cultivation work in advance and undergoing an inspection. In addition, before being harvested, it seems that they will be shipped after confirming once again that they have been cultivated according to the standards. "Chiba eco-agriculture" is an eco-friendly farming method that uses less than half of the usual amount of synthetic pesticides and chemical fertilizers, and supports us from the ground up. One of the environmental measures that Japan has already adopted is the "Global Warming Countermeasure Tax," which is a type of carbon tax that is levied on the use of fossil fuels such as oil and natural gas. The global warming countermeasure tax started on October 1, 2012, and as of February 2022, the tax rate is set to be 289 japanese yen per ton of carbon dioxide emissions.

Mythical Goto beef nurtured by the sea breeze: In the Goto Islands, Nagasaki Prefecture (Maru Goto: Kyushu consists of 11 inhabited islands and 52 uninhabited islands floating 100 km west of Nagasaki, and the beautiful sea and rich nature are impressive) It is beef from cows fattened in Japan, and the Goto Agricultural Cooperative has the trademark (regional collective trademark) right. When the age of a bovine tooth excavated from ruins in the city was measured, it was found to be from the middle Yayoi period and is said to be "one of the oldest bovine relics in Japan." Can be heard. In addition, the farmers of Goto have raised their beef with the same affection as their family since long ago, so Japanese Black Beef, a type of Tajima beef, has gained fame under the nickname 'Goto Beef'. In this way, the meat is raised with a lot of love and rich natural grass, and it seems that it is highly evaluated for its slightly different meat quality. Tajima beef is widely known as a petite and strong cattle that was born and raised with the people living here in the Tajima region of Hyogo Prefecture, which has many steep topography such as deep valleys. In addition, it has relatively thin bones, little subcutaneous fat, high-quality muscle fibers, and a perfect balance between lean meat and fatty meat.

Photochromism refers to the phenomenon in which a single chemical species reversibly forms two isomers of different colors under the action of light without changing the molecular weight. Also, two isomers are molecules with different properties. Succeeded in creating a hexatriene-based photochromic compound that undergoes a cyclization reaction with 100% stereoselectivity and a compound with a ring-closing quantum yield of almost 1. In addition, in the biradical-generating photochromic compound HABI, which suppresses dissipation, we created an ultra-fast photocoloring and decoloring reaction system. Utilizing two-dimensional microphase separation due to photoreaction of liquid crystal polymers with azobenzene side chains, we succeeded in optically controlling the morphology and orientation of thin films. We created a light-driven polymer motor that converts light energy directly into mechanical energy using an elastomer film containing azobenzene. In addition, we succeeded in controlling the planar asymmetry by photoisomerization reaction, and controlling the magnetism and superconducting properties of metal nanoparticles and thin films. We will discover new systems of photochromic single crystals and fibers capable of photoreversible shape control. We present the mechanism of reversible deformation of diarylethene single crystals by light, the estimation of generated stress, and the possibility of light-driven actuators. In addition, we succeeded in optical control of water repellency and hydrophilicity of the surface of diarylethene single crystal, and optical control of metal deposition selectivity on the thin film surface. Furthermore, as one of the ultimate performances, we have achieved control of photocoloring/photobleaching with single-wavelength light using multiphoton absorption. Research area name: Investigation of photochromism and creation of mechanical functions. Research period: 2004-2007.

When visible light (Vis) is irradiated, it returns to its original state.

生存の術: While various efforts are being made toward a low-carbon society that reduces CO2 emissions, which is one of the factors of global warming, and does not deplete resources, there is great expectation and interest in plants that absorb CO2. Plants use light energy to photosynthesize and convert CO2 into organic matter such as sugar. However, if you take a step into the idol world, there will be a tremendous competition for survival day and night (only strong and environmentally friendly ones will survive from the conflict that occurs to keep other creatures out of the way you try to survive for a long time.) Is unfolding. The plants, which seem to live quietly, devise well-thought-out ideas over the wisdom that has been cultivated for a long time in order to leave offspring. It is also essential for the survival of all living things, including humans, supports our breathing, and contributes to maintaining the composition of the atmosphere.
