Japanese Hiragana(ひらがな) was made from NHK(Japan Broadcasting Corporation), not べべのんTV. べべのんTV just a reupload of NHK's video to youtube. And it would be more accurate to say that we left the Japanese Hiragana community rather than that Japanese Hiragana was canceled. Because actually we don't know if Japanese Hiragana was canceled.
BTW, I also lose interest Japanese Hiragana something but Korean Hangul not canceled(I originally wanted to canceled this)
