With Trouble
Valuable, Rare
adverb, noun
When there's nothing but folds and angles, you have quite a mess. This word means with trouble because you certainly aren't traversing along a nice, flat piece of space-time, are you? Nah, it's all angled and folded.
折角 is one of those tricky Japanese words that doesn’t have one neat translation in English. The nuance is that something has come about with trouble, either through someone’s efforts, or a stroke of luck. It often implies regret, and is used in situations where you want to express that valuable opportunities, advice, or hard work were in vain for some reason. It’s also used to underline a rare chance that shouldn’t be missed.
せっかく
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Watch out for the せつ changing to せっ, though. Another thing you have to go through with trouble, I'm afraid.
折角苦労して手に入れた宝石を、彼女は気に入ってくれなかった。
She didn't like the jewelry I went through so much trouble to get.
折角ですが、これ以上妥協することは出来かねます。
We appreciate the trouble you’ve gone to, but we're not able to compromise further on this matter.
おれの折角のちゅうこくをむだにするつもりなのか？
Are you going to throw away my valuable advice?
うーん。折角イメチェンするいい機会だし、後ろ髪を三十センチくらい切ってもらおうかな。
Hmm. It's a rare opportunity to get a makeover, so I think I'll have my hair cut about thirty centimeters at the back.
