Hi Will as a Japanese I watched videos about this issue. Many ppl believe that his mother and sister lied cuz they looked very nervous and unnatural during some of the interviews. Also his dad may be the one who took him away. Some people claim they saw him working at a Male revue club(ホスト)in Tokyo now.
Is it possible though? He is an adult now if he is still alive. In my country, you need to use personal ID for education and working purpose. Without ID, you couldn't do anything actually. If he is using it, surely someone will find out his location and movement. But I am not Japanese, so I don't know how Japan system works. Unless his family make a fake one for him. Otherwise, most likely this kid met an accident after he left the house on my perspective.
幫忙翻譯一下 樓下 フユツキ 21的留言（雖然will 應該英文很好不太需要XD 但可以讓更多觀眾看看） 嗨 Will, 作爲一個日本人看到關於此案的影片（想分享一下） 許多（日本）人認為智廣母親與姊姊其實是在撒謊，因為在許多的訪談中，可以發現到她們非常緊張以及不自然的反應。 而他的爸爸可能就是將他帶走的人。目前許多人稱他們是在東京一家男公關店看到智廣（感謝下方@徐彤 留言提醒） Hi Will as a Japanese I watched videos about this issue.

福爾摩斯名言：Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. 既然外出路徑沒有任何綫索，那麽很可能他根本就沒有外出；母親殺害他後可以同時報警並使用車輛棄屍，只要有足夠重物，屍體可以在河流中永遠不被發現。母親在責罵過程中誤殺兒子，為照顧女兒的關係，也在女兒幫助下隱瞞了真相逃避刑罰，也是存在這種可能。另外，從肢體語言看（話劇表演録影），智廣並不是衝動型人格（即使在表演中他的面部肌肉也很放鬆，頸椎和雙肩沒有傾斜，這顯示其身體不習慣激烈情感表達）。辦案警官在案發後應該強化訊問家人才對。
