karakkaze
{{Short description|Strong, dry wind in Kantō, Japan}}
Karakkaze (空っ風、からっかぜ) refers to a kind of strong, dry wind that occurs in the Kantō region of Japan.
Overview
Karakkaze is formed when wind gusts cross atop the mountains in the Jōetsu region and experience a drop in both temperature and atmospheric pressure. Water vapor in the air falls as rain or snow on the mountain, so the wind that then crosses over the mountain becomes dry.{{cite web |title=空き家の強風対策について。群馬県のからっ風の被害はバカに出来ない? |url=https://ie-tochi-story.jp/blog/property/vacanthouse/%e7%a9%ba%e3%81%8d%e5%ae%b6%e3%81%ae%e5%bc%b7%e9%a2%a8%e5%af%be%e7%ad%96%e3%81%ab%e3%81%a4%e3%81%84%e3%81%a6%e3%80%82%e7%be%a4%e9%a6%ac%e7%9c%8c%e3%81%ae%e3%81%8b%e3%82%89%e3%81%a3%e9%a2%a8%e3%81%ae/ |website=Ie Tochi Story |access-date=14 June 2022}}{{cite web |title=からっ風の意味と時期とは?いつの季語?木枯らし、やませとの違い |url=https://jpnculture.net/karakkaze/ |website=日本文化研究ブログ - Japan Culture Lab |access-date=14 June 2022 |language=ja |date=23 December 2017}}
Gunma Prefecture is famous for its karakkaze in winter.{{cite web |title=群馬県ってどんなとこ? |url=https://www.pref.gunma.jp/01/bu0100009.html |website=群馬県の公式HP |publisher=Gunma Prefecture |access-date=14 June 2022}} Other names include Jōmō Karakkaze (Jōmō is an old name for Gunma) and Akagi Oroshi (karakkaze that blows down from Mt. Akagi). In Jomo Karuta, karakkaze is featured on the 'ra' card.{{cite web |title=Jomo Karuta.

Besides Gunma, Nasunohara in Tochigi Prefecture and Hamamatsu in Shizuoka Prefecture both are famous for karakkaze; there it is called Nasu and Enshu Karakkaze respectively.
Effects
A phenomenon known as foehn wind suppresses cooling, which creates less snowfall in the surrounding area. This also creates a strong wind chill due to the strength of the winds.
Minor inconveniences caused by karakkaze include:
- interrupting outdoor sporting matches
- drying out skin (Gunma has ranked last in terms of beautiful skin according to a national survey on skin care){{cite web |title=3年連続美肌ランキング最下位からの巻き返し 生産・食・体験・開発 オール群馬のプロジェクト「こんにゃくセラミド美肌プロジェクト」がスタート |url=https://www.atpress.ne.jp/news/183873 |website=www.atpress.ne.jp |date=17 May 2019 |access-date=14 June 2022 |language=ja}}
- annoying locals (due to its loud howling sound)
- blowing laundry off balconies
However, it is strong enough to cause more serious damage. Wind speeds can reach up to 20 kilometers per hour, causing damage to old houses.{{cite web |title=からっかぜ【空っ風】 {{!}} か {{!}} 辞典 |url=https://kids.gakken.co.jp/jiten/dictionary02100967/ |website=学研キッズネット |access-date=14 June 2022 |language=ja}}
During the 1970s, residents in Ōta, Gunma complained that karakkaze was blowing up dust from the potato fields and spreading it throughout the city. They claimed the wind blew dust into their houses and prevented them from drying their laundry.
In February, 2021 a wildfire broke out in Ashikaga, Tochigi. The fire burned for nine consecutive days. In combination with an accumulation of dried leaves and debris, karakkaze made it difficult for helicopters to fly properly, delaying the fire department from being able to stop the blaze sooner.{{cite web |title=足利の山火事の延焼について {{!}} オウミ技研 |url=http://net-o.co.jp/ashikaga-forest-fire-wind/ |website=net-o.co.jp |access-date=14 June 2022}}
