Hey Massaki,
the “#page-holder-35” suffix is supposed to be in the URL :) it is the part that tells the browser on which part of the page to start displaying the website (see e.g. this resource for more info on the hash URLs). Otherwise the website would always open on top of the front page, i.e. the menu would not make sense. When you enter that URL (http://www.facem.jp/#page-holder-35) into your browser, does it load the front page of the website on the “FaceM サービス” section?
Sincerely,
