How to customize menu bar in mobile view

Hi Zoho,
I am designing my site www.kidstaktil.com and found that the mobile view shows an english text "more" on the menu bar.

Please see the attached picture.

Since my site visitors are japanese and my site must be in japanese, this looks weird.

Is it possible to edit this "more"-menu to make it appear in Japanese? (it would be great if I would be able to enter whatever text I want in this "more"-field).

Looking forward to hearing from you on this issue.

Best Regards,
Bjorn
