KOIKURENAI is one of the variety of carrots. It contains a lot of Lycopene, even though other carrots have few that. It have got a food with nutrient function claims since 2016 in Japan. Usually,We have been able to harvest KOIKURENAI only just for a month in the same region. However NKagri has supplied 500,000bags of them for 6 months, because he builed the team with farmers to relay cropping them. We use IoT for this strategy. We get to know the best season when KOIKURENAI has most Lycopen in each region with sensors which put up on 5 areas in Japan.
