実力を発揮する

You use this when you want to highlight someone’s performance in a high-stakes situation. It’s perfect for sports, exams, job interviews, or even just nailing a difficult presentation. The key is that the ability was there all along, but it’s now being *demonstrated* effectively. It’s about potential becoming reality under pressure. Think of it as unlocking a hidden level in a game. You finally got the cheat code to show your best.

• A gamer finally beats a notoriously difficult boss level. They 実力を発揮した (showed their ability).
• A student who usually struggles aces a crucial final exam. They 実力を発揮した (showed their ability).
• An athlete performs exceptionally well in the Olympic finals. They 実力を発揮した (showed their ability).
• A shy musician delivers a stunning performance at a concert. They 実力を発揮した (showed their ability).
• A chef creates a masterpiece dish under intense competition. They 実力を発揮した (showed their ability).

Use 実力を発揮する when someone truly shines under pressure. It’s for situations where the outcome is important. Think of a championship game, a final job interview, or a critical presentation. It’s also great when someone overcomes nervousness or doubt to succeed. It implies that the skill was always present, but the circumstances allowed it to be showcased. It’s the moment potential meets performance. Did you finally show your boss you're not just a coffee-fetcher?

Don't use this for everyday tasks or casual successes. If you just made a decent cup of coffee, you probably didn't 実力を発揮する. It’s also not for luck or random chance. If you stumbled into winning the lottery, that’s not showing your ability. Avoid it for situations where the skill is minimal or the stakes are incredibly low. Making your bed perfectly isn't usually a display of 実力. Unless your bed-making skills are legendary, then maybe.

Learners sometimes confuse this with simply *having* ability. 実力がある means 'to have ability'. 実力を発揮する means to *show* that ability. Another mistake is using it for minor achievements. It’s like using a sledgehammer to crack a nut. Or trying to order a latte with just 'coffee'.
