Questions & Answers about keiyakukikan ga nagai ka mijikai ka ni kakawarazu, kaiyakukin o kakuninsuru.

What does 〜か〜かにかかわらず mean in this sentence?

It means regardless of whether A or B.

So:

• 契約期間が長いか短いかにかかわらず = regardless of whether the contract period is long or short

This pattern is used when the result or action in the main clause does not change, no matter which of the two possibilities is true.

A useful pattern to remember is:

• AかBかにかかわらず、C
• Regardless of whether A or B, C

In this sentence, C is:

• 解約金を確認する
• check the cancellation fee

Why are there two か particles in 長いか短いか?

The two か particles mark two alternatives.

• 長いか短いか = whether it is long or short

The first か separates the first option from the second:

• 長いか短い
• long or short

The second か closes the whole whether A or B expression before にかかわらず.

So the structure is:

• A か B か
• whether A or B

This is very common in Japanese:

• 行くか行かないか分からない = I don’t know whether I’ll go or not
• 高いか安いかを見る = check whether it is expensive or cheap
