I want to change the letters.

I am operating a member website.
After logging in, we will publish a page displaying logout items.
However, I can not change it by English notation only for the logout part for some reason.
I want to change it to Japanese.
The file which seems to have a part to change is “class-theme-my-login-template.php”.

public function the_user_links() {
		echo '<ul class="tml-user-links">';
		foreach ( (array) self::get_user_links() as $link ) {
			echo '<li><a href="' . esc_url( $link['url'] ) . '">' . esc_html( $link['title'] ) . '</a></li>' . "\n";
		}
		echo '<li><a href="' . wp_logout_url() . '">' . self::get_title( 'logout' ) . '</a></li>' . "\n";
		echo '</ul>';
	}

Changing the part of ‘(‘ logout ‘) in the above will change the target part, but even if you change the letter it will not be what you thought.

I am Japanese, it is useless English, but I am glad if you can help me.
