Today, September 1st (Friday) is one of the miscellaneous festivals, “Nihyakutooka”. It means the 210th day from the beginning of spring, and typhoons have long been feared as an unlucky day for farmers.
Since this period coincides with the flowering of rice in many regions, it was intended to call attention to rice cultivation in particular. (Currently, this is not generally applicable due to differences in breeding and planting times.)
Important time for rice cultivation
Heavy rains and strong winds during the rice flowering period affect the rice harvest.
One of them is flood damage. When fields are flooded by heavy rain, the ears of rice remain submerged in water and become useless.
In addition, strong winds can break stems and knock down rice plants. The head of the rice plant that has absorbed the rain with its ears is heavy, so it easily topples over. Harvesting fallen rice requires a lot of effort.
Also, typhoons cause the foehn phenomenon, and when the rice is exposed to the high temperature and dry wind during the heading stage, it releases all the moisture and may wither into a state called white head.
In this way, the typhoon around the 210th caused damage to rice plants in various ways.
Today, in addition to ingenuity such as breed improvement and cultivation management, such as staggering the planting season, the impact is less than it used to be. However, considering that crops have been damaged by large typhoons in recent years, it can be said that you should be prepared and take adequate measures during this time.
When is the most typhoon landfall?
The 210th day has long been said to be an unlucky day for typhoons, but what is the reality? Any of the days from August 31st to September 2nd can fall on the 210th day.
For the typhoons from 1991 to 2022, the number of landfalls per day was 1 on August 31st, 0 on September 1st, and 0 on 2nd. On the other hand, there were two landings on August 30th, and one or more landings every day from September 3rd to 9th.
Looking only at the statistics for this period, it would be unreasonable to call the 210th day a typhoon’s bad day or a typhoon’s unique day. You can see that.
Also, although the number of typhoons that occur is highest in August, the number of landfalls is higher in September.
It can be said that the 210th is the beginning of the season when many typhoons that cause great damage come, so it seems good to think of the 210th as a “day to review preparations for typhoons.”
Typhoon No. 9, Typhoon No. 11, and Typhoon No. 12 still exist today, and there are concerns about their impact. Please check the typhoon information carefully and review your personal preparations.
