    This morning in Akita Pref at only 47m asl. At least, it's finally sunny.

    This is from a local weather news. Snowman = heavy snowfall. Blue, Green and Brown are major ski regions (Blue = Hokkaido on Sea of Japan side, Green = Tohoku on Sea of Japan side and Brown is roughly the snowiest region of Central Honshu). So, local weather experts think it's likely to snow a lot between 7th's noon and 9th's evening. Some regions might get another 100cm. However, I rather want to keep the snowfall for 2022 or 2023. I mean, my motivation to come to this forum is to make more people from abroad get interested in skiing in Japan. This season = most people can't fly.

    Delayed reply, but...

    I know that storm very well. Mid Feb (or Jan) 2016 I did a looong bus ski trip from Sasebo to ski Mizuho Highland. Snowed all day on arrival, and we did overnight near Iwakuni. Day 2 skiing was cancelled since the roads were closed to get there, so we started back to Sasebo. None of the expressways were open so the normal 4-5 hour drive took 12 hours. Only saving grace was we weren't driving. I recall going through the streets of Fukuoka with high winds and blowing snow. I believe Sasebo said it was a 50 year (or 100) snowfall.

    It seems it was late January of 2016. The snowdepth of Nagasaki city's downtown reached 17cm, which is the new record. The temperature of a city in Kumamoto prefecture at only 150m asl dropped down to minus 9.8C and it has also become the new record low temperature (JMA started recording the temperature there even before the world war 2, but still it has become the lowest temperature there in 2016). 74 weather stations of JMA had the record low temperatures when the cold wave hit Japan in 2016.

    Even Japanese Wikipedia has the cold wave of 2016.
    https://ja.wikipedia.org/wiki/平成28年豪雪

    I remember the cold wave just because it hit one of my favorite orchards in Kumamoto pref, killing some young citrus trees I was going to get. I mean, here in Japan, March is the best time to plant citrus trees. I usually order new trees in December and they are delivered to my farm in March (or early April), however, the cold wave killed young citrus trees that were supposed to be delivered to me in late March.

    Haha, Japanese wikipedia even has it. It's the cold wave hitting Japan in February of 2014.

    Low pressure trough initially in northern Sea of Japan, means a westerly wind and snow in Gifu.

    Ski Jam will get absolutely caked. Looks delicious at the moment.

    A bit about something related to Gifu and prefectures around Gifu,

    A long time ago, JMA had weather stations in "strange places". Now, JMA basically have weather stations only in the places where there are enough population. For example, on the border of Gifu Prefecture and Shiga Prefecture, there is Mt.Ibuki and JMA used to have a weather station on Mt.Ibuki and the official biggest snowdepth record of the weather station is 1182cm (almost 12m!).

    The official 24 hour snowfall record of JMA is 230cm, and it was recorded in Magawa. JMA don't have a weather station there now, though. The weather station was made to construct a dam there. Magawa dam is near Tateyama station, Toyama Prefecture. 0cm, next day, 230cm, crazy.

    This was filmed at 9:30 am Today (it's from a local tv news). Self Defense Force were dispatched to the region to clear the snow, but another even stronger cold wave is hitting the region anytime soon. Akita Pref is snowy, but the city in the video is at only 40 or 50m asl and the city is not in a ski region, so the snowfall was a bit too much for the people living in the city.

    Some weather news are saying now that some regions might get 200cm in the next 72 hours. The twitter video below was filmed in Akita Pref at only 47m asl the day before yesterday (January 4th). It's still the first week of January, but some people have already got buried like that and died this season unfortunately.

    Yep. Actually JR, JAL and ANA have already announced some amount of their lines / flights won't run / fly due to heavy snow (and high wind)

    I have been reading a bit about wind, I can see it tomorrow which could be a good rest day, snow may not arrive until late anyway. From Friday not so much wind predicted and should be good conditions if not too much snow..

    I imagine there will be quite a few people preparing their places for the blast. Tomorrow will be a good day for that.

    Westerly wind because of the low pressure trough. Normally, this would rake the coast of Nagano & Niigata. But there's a lot of cloud associated with the low, which will sit just off the coast for about 6 hours off Nagano & Niigata. Gifu will cop a pasting.

    If local weather forecasters and weather websites are correct, ski resorts like Arai, Charmant Hiuchi and Geto Kogen might get 600cm of snowdepth by January 10th (Now, Charmant Hiuchi has 330cm, Arai and Geto have about 400cm). 600cm of snowdepth in early January? Really?. A Japanese weather website Tenki.JP has snowfall forecast on ski resorts. However, they let AI automatically calculate amount of snowfall coming and it's actually inaccurate. I mean, they almost always underestimate the amount of snowfall on ski slopes. For example, when the say 10cm, it's actually very often 30cm. Now, Tenki.JP say Charmant Hiuchi will have 51cm on 7th, 118cm on 8th and 49cm on 9th. So, they are forecasting 218cm in 3 days. I don't trust them, though (I understand forecasting amount of snowfall on ski slopes is very difficult even now)

    When there is a westerly in Niigata, resorts further inland miss out. The places that get a lot of snow are all within 10-15km from the coast, since they are not blocked by coastal mountains. This includes Charmant, Itoigawa Seaside, while Arai is only slightly further away. I've seen 70cm overnight on a westerly.
    Myoko Suginohara also does quite well on a westerly.

    A 18 - 24? hour snowfall forecast from a local tv program. It says "By next morning in snowy places". I'm actually not sure if "next morning" means 6am, 7am, 8am, or 9am. Anyway, it's roughly 18 - 24 hour snowfall forecast. So, they think it's likely to snow in some strange places such as Kyushu and Shikoku.

    Ok, so it looks like the Low will track further to the east than expected.
    This means that the northerly should kick in some hours earlier than expected.
    But the anticlockwise circulation means that the initial precipitation is more likely to be rain or wet snow on the resort bases in Niigata/Nagano. Should get cold fairly quickly after that, however.

    Light snow driven on howling wind here. Not heavy enough to accumulate but NHK forecast suggests becoming heavier tonight.

    A big gust of wind came through at about 12 to signify the start. Had to duck for cover with all the snow being thrown off the trees. By 1:30 it really started to come down in Echoland. It is dumping down now. All my clearing is updated but I dare say I will be out there again late afternoon.

    I'm now in Ibaraki. Our car's thermometer was showing the outside temperature was 11 or 12C an hour ago, very sunny without a cloud:p (We'll drive north = Tohoku later on)

    I took this picture about 10 mins ago. Very sunny without a cloud and warm. It's common, though. When a cold wave hits Japan in winter, Ibaraki's coastal line is usually very dry and sunny. 12C now, but after a few hours of drive, we'll face -12C. Our farmland is the warmest of Japan in winter if compared to the other cities in the same latitude and the coolest in summer thanks to the sea water.

    It's dumping at JMA's weather stations around Morioka - Shizukuishi - Hachmantai now. JMA don't have a weather station close enough to ski slopes in the region, but JMA's weather stations in the region having snowfall usually means that it's snowing quite hard on ski slopes in the region. Between 3pm and 4pm, the snowdepth increased by 11cm. 11cm in an hour, where it's flat and a bit away from a mountain. It's impressive.

    Was a sunny day in Madarao, a little bit of snow around 2-3pm, maybe 1cm and big gusts of wind.

    As predicted the proper snow hasn't arrived to this region yet.

    Was thinking the same, the wind came and went before it started really dumping.. More or less, at least at Madarao.

    Nozawa Onsen running at around 6-7cm per hour for the last 4 hours, which is heavy. (26 cm in 4 hours)

    Shirakawa in Gifu prefecture is running at 8cm/hour. (24cm in the last 3 hours, 30cm in the last 4hr)

    Gifu, Toyama, Ishikawa, Fukui, Niigata, etc have been getting very heavy snow since several hours ago. Tarumi (Gifu Pref only 190m asl) had +14cm in an hour.

    As of yesterday, most major ski resorts had enough snowdepth, so they actually don't need mega snowfall now. Only 20 - 30cm of snowfall on ski slopes overnight can make the ski day very enjoyable. In that sense, most major ski resorts will have enough fresh snow tomorrow (Friday), or some ski resorts might have too much fresh snow this weekend:p

    Charmant Hiuchi's official twitter says they had +70cm at the bottom overnight. As of yesterday, the snowdepth there was 330cm, so the ski slope's snowdepth reached nearly 400cm.

    Urabandai (Highland around Mt.Bandai, Aizu region, Fukushima Pref) at about 800m asl last night. The region had 20cm overnight. Not big snowfall, but enough fresh snow to make the ski day enjoyable today.

    The low has moved off, and we are now in a light wind regime. And the sea/lake effect cloud is currently a westerly.

    It will turn to the north, on a lighter wind. However, it's not the huge dump(200cm?) that was expected in resorts.

    Shirakawa ended up with 57cm
