What is the character for resistance?


What is the character for the word resistance. I'm looking for the term in the
sense of "I feel resistance towards taking on this challenge".




In that context, you really do not have many choices. It would be either
「[抵抗]{ていこう}」 or 「抵抗[感]{かん}」.

> "I feel resistance towards taking on this challenge."

could be said as:

> 「この[挑戦]{ちょうせん}を[受]{う}けるのは抵抗がある。」
>
> 「この挑戦を受けることには抵抗感がある。」
>
> 「この挑戦を受けることには抵抗感を感じる。」
