Each space you create, including your personal space, is automatically created with a home page – the first page you'll see when you navigate to the space – which you can edit to suit your needs, and you can create any number of child pages to store the content and information you need. Spaces don't nest – you can't have a space within a space – but pages do, so you can create as many levels of hierarchy as you need using pages.
Each space also has its own blog, allowing you to share news and make announcements. Blog posts are a great way to keep people involved in what's going on in your team or project.
You can set different levels of access for each space using its permissions.

Confluence でスペースを表示する主な方法は 2 通りあります。
You can mark a space as a favourite by choosing the star icon to the right of it, or categorise the space to get easy access to the content that's most relevant to you.
また、ヘッダーのスペースメニューには、最近表示したスペースの一覧も表示されるので、最も頻繁に表示するスペースに素早く移動できます。

The Spaces List macro allows you to display a list of spaces on a Confluence page, and filter them by category, if you need to.
