Japan Sumo Association opened an official account this month in Messaging apps LINE. What kind of information do they show there? It's these.
What a Cute! They showed many cute photos as well as these. Besides, it is almost every day!
They appeal to youths for sumo by using LINE. Sumo is the national sports of Japan, but it is traditional culture and is a ceremony to God(Shinto). Well, it's the genre that youths do not like. Therefore they send a friendly atmosphere in LINE. Furthermore, they hold the photograph exhibition which collaborate with LINE in Ryougoku Sumo Hall.
However, unfortunately their account can check only in Japanese region.
