Some improvements can be made such as fixing the missing security headers listed below:

Missing security header for ClickJacking Protection. Alternatively, you can use Content-Security-Policy: frame-ancestors ‘none’. Affected pages:
https://sp.nicovideo.jp/ for iPad’s UA

Missing security header to prevent Content Type sniffing. Affected pages:
https://sp.nicovideo.jp/ for iPad’s UA

Missing Strict-Transport-Security security header.

Missing Content-Security-Policy directive. We recommend to add the following CSP directives (you can use default-src if all values are the same): script-src, object-src, base-uri, frame-src

There was also no website firewall detected during the scan which means the site is vulnerable to hacks and DDoS attacks.

Lastly, I ran a malware scan with VirusTotal on the domain nicovideo.jp and no security vendor has flagged the domain as malicious. You can see the same here: VirusTotal scan for the site Nicovideo.jp.
