Posting into the void (kabeuchi)
Overview
Kabeuchi (hitting against a wall) is slang for continuing to post your own thoughts and feelings one-sidedly on social media without expecting reactions from others. Like practicing tennis or table tennis against a wall, when you hit the ball it only bounces back off the wall, and there is no opponent.
The owner of a kabeuchi account may not care about having few followers. They keep posting even without likes or replies. Kabeuchi tends to put more weight on sorting out your own thoughts and feelings than on communicating with others. You could also call it using social media in place of a diary.
Question boxes and kabeuchi
Some people use their answers in a question box like kabeuchi. On days when no questions come, one way to use it is to give yourself a topic and answer it. Or you sort out your own thoughts through your answers. You use the question box less as a way of replying to senders and more as a dialogue with yourself.
A kabeuchi question box may look lonely at first glance. But some readers see a special depth in answers written as kabeuchi. Because you aren't worried about other people's reactions, your true feelings may come out. You don't try to get a laugh, you don't think about going viral, and you simply put your own thoughts into words. This attitude can end up striking a chord with readers.
The value of kabeuchi
Kabeuchi assumes that "no one will read it." Even kabeuchi accounts on social media have people quietly watching.
Kabeuchi has value in writing for yourself. You put your thoughts into words without worrying about other people's judgment. This act helps with metacognition and understanding yourself. You use the question box not only as "a tool for communicating with others" but also as "a tool for a dialogue with yourself." Kabeuchi is another way to use a question box.
