How to express the idea of 'availability' in Japanese, covering whether something is obtainable, someone is free, or a service is offered.
このサービスは利用できますか？
Is this service available?
Expressing whether an item or resource is available, in stock, or can be obtained.
The most basic way to say something is available is to use the verb ある (to exist, to be). For inanimate objects, this is the natural choice.
この本はまだありますか？
Is this book still available?
在庫があります。
It's in stock (available).
Literally 'obtainable'. Used in formal or written contexts, such as product descriptions or official announcements.
A common phrase meaning 'can be obtained' or 'is available'. Slightly more colloquial than 入手可能.
Expressing whether someone is free, has time, or can be reached.
Means 'free time' or 'not busy'. Use 暇ですか？ to ask if someone is available casually.
明日暇？
Are you free tomorrow?
Means 'convenient' or 'available' in terms of schedule. More polite than 暇.
来週の月曜日は都合がいいですか？
Is next Monday convenient for you? (Are you available?)
Literally 'empty' or 'vacant'. Used for time slots or schedules. 空いていますか？ asks if someone is free.
午後は空いていますか？
Are you free in the afternoon?
Literally 'hands become free'. Used when someone finishes a task and becomes available.
手が空いたら手伝って。
Help me when you're free.
Expressing whether a service, feature, or option is offered or accessible.
Means 'can be used' or 'available for use'. Standard for services, facilities, or features.

The English noun 'availability' does not have a single natural Japanese equivalent. Instead, use verbs like ある, 利用できる, or adjectives like 暇 depending on context. Translating literally as 可用性 (かようせい) is technical jargon and rarely used in everyday language.
可用性
availability (technical, e.g., system uptime)
この製品は現在入手可能です。
This product is currently available.
この薬はどこで手に入りますか？
