Iraku Takuji’s Unexpected ‘Human Task Management’ Notebook Arrives! The Third ‘QuizKnock × Lawson’ Collaboration is Creating a Buzz

Well, it’s finally here. Iraku Takuji’s “University of Tokyo-born knowledge group,” QuizKnock, has teamed up with Lawson again, and it’s seriously testing our willpower to resist buying. This is the third time they’ve done this. Previous collaborations sold out instantly each time, so I bet a lot of you saw this announcement and immediately braced yourselves, thinking, “This is definitely going to be a scramble.”

What’s really setting social media alight this time is a product name that’s so quintessentially ‘Iraku Takuji’. It’s the “Human Task Management” notebook. You know that meticulous, unique task management style he often shows off in QuizKnock videos? A notebook that recreates that is now available at a convenience store. Who would have thought? Even if you’re not a die-hard fan, you can’t help but feel like “If I get this, maybe I can tap into a fraction of that brilliant mind.” It’s shaping up to be something of an ‘enlightenment gadget’.

And that’s not all. This time, besides the notebook, there’s also a wealth of practical merchandise like acrylic key holders and coasters. Plus, for those in the know, the “QuizKnock × Lawson” collaboration café, exclusively available at Lawson stores, is currently underway and proving hugely popular.

Is that ‘lucky charm’ from the ‘Todai King’ days also appearing as an exclusive item?

Now, what’s really caught our eye in this merchandise lineup is the ‘Omamori’ (lucky charm). It’s subtly listed but definitely makes its presence felt. Yes, that charm reminiscent of the ‘Todai King’ era, featuring Mizukami Sō, Suzuki Hikari, Tsurusaki Shūkō, and of course, Iraku Takuji. At a time when these four, who once reigned as the “strongest team,” are now thriving as individual talents, the fact that this exclusive charm is being offered as a bonus is just an irresistible touch.

For fans who’ve been supporting them since back then, this is a real “Are you serious?!” moment. It seems there’s a chance to get this exclusive charm as a lucky draw prize or special gift when you purchase items from the collaboration café or other eligible products. The thought of being able to attach a visual of all four of them together to your pouch or display it in your room... Speaking personally, this alone elevates the ‘rarity’ to a whole different level. It’s one of those items that makes you think, with a sense of adult pragmatism, “I need to get this now before it starts showing up for exorbitant prices second-hand.”

‘Those items’ you can only get at the collaboration café

And what’s more, you can’t overlook the items exclusive to the collaboration café. As you can tell from the info on the bundle deals this time, many of the designs, like the coasters and key holders, are only available at the café. In particular, the acrylic stands depicting each QuizKnock member are the kind you’ll definitely want to display all together.

Looking at reports from people who’ve actually visited the café, the atmosphere is a total “sanctuary for intellectual curiosity and consumer desire.” There are touches like getting hand-written style message cards from the members while you enjoy your meal, creating an ambiance that feels like more than just a typical collaboration – it’s an experience you can only get here.

Here’s a summary of the must-see items from this collaboration you absolutely shouldn’t miss:

• “Human Task Management” Notebook: A legendary item that lets you simulate Iraku Takuji’s thought process on paper.
• Exclusive “Todai King” Lucky Charm: Features a four-shot of Mizukami Sō, Suzuki Hikari, Tsurusaki Shūkō, and Iraku Takuji. Guaranteed to be hard to get.
• Collaboration Café Exclusives: Coasters, key holders, acrylic stands. A lineup fans will want to collect every piece of.

Honestly, even among the collaborations we’ve seen this year, it’s rare to find one so packed with items that fans truly want. I think Iraku himself mentioned on his social media that he only included things he personally wanted. True to his word, the selection really makes you smile with its clever appeal.

With these kinds of collaborations, it’s standard that if you don’t act as soon as the info drops, they sell out in a flash. If you’re interested, you’d better dash to your nearest Lawson or check out the café reservation site right now. No, seriously.
