Option to unsubscribe from J-web

[melodyofmysoul.livejournal.com]

Hi! I hope this question is allowed here.

I'm thinking of subscribing to Arashi's J-web mainly to get updates and read the members' blog posts. However, upon reading the Terms of Use I couldn't find anything related to unsubscribing from the service. Although I do plan to use J-web for quite a while, I would also want an easy option to unsubscribe in case I need to do so for certain reasons.

Has anyone experienced unsubscribing to J-web? If yes, is there a standard process to do so?

Thanks in advance to anyone who can answer my question!
