シマの継承にあたり、先代に挨拶回りをした。
シマ の けいしょう に あたり、せんだい に あいさつ まわり を した。
Upon inheriting the territory, I made courtesy visits to the previous generation’s leaders.

You wanna get deep with the grammar, huh? I respect that. You’re askin’ ’bout the subtle differences between these three heavy hitters: に際して, にあたり, and にあたって. It’s like tryin’ to figure out the difference between a high-end chrome-plated pistol, a matte-black one, and one with a custom grip. They all do the same job, but they got their own feel, their own vibe.
Let’s keep it real. For the most part, they’re interchangeable. Like, 90% of the time, you can swap ’em out and the sentence still makes perfect sense. They all mean “at the time of” or “when a major event is happening.” But if you wanna talk like a true language OG, you gotta know the little details.
- に際して (ni saishite): This one is the most formal of the bunch. It’s like the kingpin’s official decree. You’d use this when you’re talkin’ about a serious, one-time event, especially one that’s got a big impact. Think about a big celebration, a critical business merger, or a life-or-death decision. It’s often used in written documents or very formal speeches. It’s got that “at this important juncture” kinda feeling.
- にあたり (ni atari): This one is a little less formal than に際して, but it’s still serious. It’s often used when you’re talkin’ about the preparation that happens right before a big event. The verb that follows it usually describes the planning or actions you take in anticipation of the main event. It’s like gettin’ your crew together and goin’ over the plan one last time before the heist. You’ll see this one a lot in official announcements or notices.
- にあたって (ni atatte): This is the most common of the three and it’s a little more versatile. It’s like the all-purpose tool in your kit. It can be used just like にあたり to talk about preparations, but it can also be used to describe the actions that happen during the event itself. It’s got a slightly softer, more conversational feel to it. You can even think of it as the “in light of” or “on the occasion of” a certain event.
So, to put it plain and simple:
- に際して: The most formal. For super important, one-time events.
- にあたり: A little less formal. Often focuses on the preparations before the main event.
- にあたって: The most common and flexible. Can be used for preparations and the actions during the event.
But listen up, don’t get it twisted. In the streets, they’re often used the same. The difference is subtle, like the difference between a high-five and a pound. They both show respect, you just use ’em in different situations.

Here’s the 4-1-1 on how to hook this grammar up.
| Form | English | Example |
| Verb (Dictionary Form) + に際して/にあたり/にあたって | On the occasion of doing [verb] | 襲撃するにあたり、計画を立てる。 しゅうげきするにあたり、けいかくをたてる。 In preparing to raid, we make a plan. |
| Noun + に際して/にあたり/にあたって | On the occasion of [noun] | 開店に際して、挨拶する。 かいてんにさいして、あいさつする。 On the occasion of the grand opening, I’ll give a speech. |
Peep this. You take a verb, the plain ol’ dictionary form, the one you use when you’re just talkin’ smack, and you slap に際して, にあたり, or にあたって right on the end. No sweat. If you got a noun, like “the deal” (取引) or “the escape” (脱出), you just put it right before. It’s that simple. You ain’t gotta mess around with no fancy conjugations.

Think of it like this: plannin’ a big heist is a major operation, right? You got blueprints, you got a crew, you got a getaway car. The whole thing is a special event.
Using に際して is like the official press conference after you’ve successfully robbed the joint and bought the police chief. It’s a formal announcement to the world. “このたびの銀行強盗に際して、多大なるご協力を感謝する” (“On the occasion of this bank robbery, I appreciate your immense cooperation”). It’s official, it’s done, it’s a big deal.
Now, にあたり and にあたって, that’s the huddle with your crew right before you bust in. The boss steps up and says, “作戦開始にあたり、一言言っておく” (“As we start this operation, I got one thing to say”). It’s the moment before the action, the start of the big event. It’s about the positive, forward-movin’ energy of gettin’ the job done. You wouldn’t use this grammar for somethin’ negative, like gettin’ pinched by the cops. This is for when you’re makin’ moves, see?

Here’s some new lingo to add to your arsenal.
密輸する (みつゆする)
English: To smuggle.
Yo, peep this. To “mitsuyu suru” is to move somethin’ on the low, somethin’ that ain’t supposed to cross no borders. We ain’t talkin’ ’bout your everyday mail, ya dig? This is that contraband, that stuff the feds are always sweatin’. Think of it like this: you got some rare kicks, some exclusive gear you can’t get nowhere else. You gotta get it from point A to point B without no one peepin’ your game. That’s “mitsuyu suru.” It’s all about that covert operation, that under-the-table hustle to get the goods where they need to go. Straight up.
引退する (いんたいする)
English: To retire.
Aight, listen up. To “intai suru” is when a real one decides to hang it up. You been in the game, you made your name, you put in the work. But now, it’s time to step back from the grind. Maybe you’re a top dog in the business, a legendary emcee, or a street kingpin. You ain’t gettin’ taken out; you’re choosin’ to leave. It’s like when a rapper drops the mic for the last time and says, “I’m out.” You’re retirin’, goin’ legit, or just passin’ the torch to the next generation. It’s the end of an era, you feel me? You’re a legend, and now you’re enjoyin’ the fruits of your labor from the sidelines.
譲る (ゆずる)
English: To hand over; to yield.
Check it. To “yuzuru” is all about passin’ somethin’ on. It ain’t about gettin’ beat or gettin’ punked. Nah, this is a power move. You got your turf, your spot, your title, and you decide it’s time to let your right-hand man, your protege, take the reins. You’re givin’ it up, but on your own terms. It’s like the OG of the crew handin’ over the keys to the kingdom to the youngblood who’s proven his worth. You’re yieldin’ your position, but you still command that respect. It’s a transfer of power, a sign that the legacy continues. Dig it?
綿密な (めんみつな)
English: Meticulous; detailed.
Yo, “menmitsu na” is how the real bosses operate. This ain’t no sloppy, off-the-cuff move. This is that detailed, calculated, every-little-thing-planned-out type of action. Think about a heist movie. The crew ain’t just runnin’ in guns blazin’. They got blueprints, they got timings, they got every exit covered. That’s “menmitsu na.” It’s that meticulous planning, that attention to every single detail to make sure the job goes off without a hitch. You gotta be precise, you gotta be thorough, ’cause one wrong move and it’s all over. It’s that mastermind strategy, you know what I’m sayin’?
立ち上げる (たちあげる)
English: To launch; to start up.
Aight, so to “tachiageru” is to build somethin’ from the ground up. You got a vision, a hustle, and you make it a reality. We ain’t talkin’ ’bout joinin’ someone else’s crew; we talkin’ ’bout startin’ your own empire. It’s like launchin’ your own record label, your own clothing line, your own operation. You’re the founder, the shot-caller, the one who took a dream and made it tangible. You’re kickstartin’ a whole new movement. It’s that entrepreneurial spirit, that ambition to create somethin’ that’s all yours. You’re not just in the game; you’re changin’ it. That’s wassup.
