[3] Though primarily an internet service, as of November 2024 WNL also does simulcasts or inserts some of its programmes in other paid TV or local television channels around Japan.

The channel is focused on weather and meteorological information for Japan, including typhoons, volcanic activity and earthquakes.

In late February 2021, a video where then presenter Saya Hiyama [ja] switches from light-hearted banter to an earthquake early warning in a few seconds became a viral phenomenon on internet and gave WNL some renown overseas.

[11] Another clip of Hiyama posted 12 November 2021[12] has earned more than 13 million views on YouTube in part because it was featured on the Daily Mail website.

Hiyama, who joined WNL in 2018, left the channel on 30 March 2024;[13] her last programme, Evening, reached 23,000 live viewers on YouTube.
