Hey Denis,
by default, the meta title in Fuji is set to follow the pattern “[Current page or post title] | [Name of the website]”. However, this can be overridden by the SEO Options module which is built into the theme and can be accessed from the admin menu. The “home title” field is what you’re after (I’ve set it to “Društvo Touhou” to provide an example).
Best,
