I'll try browsing to oldje.com. Hmm, when I try to access it, the site might not exist, or it could be under development, expired, or maybe a phishing page. If the site is legitimate, perhaps it's a resource for old Japanese culture, or maybe related to a game or service that's discontinued. But the main issue here is about getting a free password for "extra quality". The user might be referring to a membership that offers higher quality content, similar to sites that have a free tier and a premium (paywalled) version with extra features.
