I hope you showed Joey the toilet paper hat. He should be proud of that level of ingenuity.

With Joey on tour, it should be a surprise to show him the tissue roll contraption when he gets back. Just wait for him to come home and wear the thing without acknowledging it at all.

Aki has been making "Why Japan" for so long that, with the toilet paper hat, she has reached the stage of "Why Aki?!"

The sarcasm of the friends not supporting her and her dream of making the toilet hat... lol

Japan: *discontinues a product because of how ridiculous it is* Aki: Your sins have not been forgot.

The level of commitment for Aki to raise that score is crazy. Such dedication. Hopefully you're okay!

The toilet paper hat actually would be useful when you caught a cold and your nose is running none stop and you sneeze like crazy. Or if you're in a phase where your nose is bleeding quite often and strong and for some reason you haven't run to the doctor's yet to get it fixed.

What did we learn today, Aki has really good breath no matter what.

“The silly and wacky things Aki does when Joey isn’t home!” 🤣

I love how instead of thinking the breath tester just doesn’t work, Ali just assumes she’s the problem and proceeds to torture herself

The toilet paper hats is useful, fashionable, and a work of art Tis quite the inspiration creating

you tried so hard to make the breath thing work, i admire your dedication a true scientist

Aki's design looks significantly more sturdy than the picture she based it on. Good work.

That toilet hat is by japanese inventor Kenji Kawakami, he creating many weird, not exactly useful tools, he created term Chindōgu. ;)

Should've tried the breath thingy after brushing and washing to see if it reacted to that.

I've been praying to tentacle-sama for a new "why!? Japan!" and he's finally delivered! And with the toilet paper hat too lol 😂

The toilet paper hat could actually be really useful in some cases: if a person has strong hey fever and is at home! Congrats on making it!

Like legit that toilet paper hat would be so usefull if it could be customised with wetwipes or other types of paper. Just the cleaning would be sooo.... Aaarhg so good.

"It's just hot glue" Hey now, don't be knocking on the art of the hot glue, haha, that stuff's versatile as heck. I love the ad reel for the toilet paper hat, especially around 9:17, looking off in the distance with the slow smile. Like a proper classic commercial

Aki looks so happy after her creation! She's soo sweet😭😭❤️❤️

I think Aki could've blown into the iPod like they do with breathalyzers

glad to see you're doing better. love the videos. stay safe.

Ok so you have a mint and then the breath checker will detect a very strong smell... ?? Also, I think you have to take a deep breath and then blow constantly on the breath checker, rather than huffing in and out on it lol

Been a while since you've done one of this. I love this series so much

I saw that toilet paper hat on TV as a kid and was totally convinced Japan was a weird country. Props for your effort in handmaking your own helmet!

Aki:(eating a bunch of random smelly stuff then breathing into an iPhone shuggle) Joey:Oh look, my wife is filming another KZfaq video.😊

When you try not to groan in frustration with her just panting into the thing when she just needs to blow into it like she's trying to blow up a balloon like *omg*. Funny af tho

Aye, glad to see this series back.

So many great Aki faces were made as she tried to get a cheap machine to say her breath stank.

Finally .... after an eternity this series of " nande nihon / why japan "is backk . Yeahhhhh

Ay lmao that last part with Aki's friends not supporting her made me laugh out loud so much.

Even though this may not be the most financially Savvy idea I can suggest, I think it would be a fun turning point for the series for you to take the personal ingenuity route the way you did with the toilet paper hat! To make these wacky non existant products/things and bring them to life yourself, put it in use, and get reactions would be very fun to watch!

The breath checker was funny 😭😭😂😂

I love how happy she is when the toilet paper hat worked lol

Perfect video for the holidays! Something people can make for a last minute Halloween costume idea, lol. XD

maybe the smelly breath detector is actually a breathalyzer to detect alcohol levels for preventing drunk driving, lol.

Aki reached the point of making her own chindogu

nice hat .....hey i think the bad breath thing depends on what the sensor is made to detect. it doesn't necessarily detect bad food smell it probably detects some molecule that "bad breath" bacteria create. the way we could know is if you could find the part number of the sensor and see which molecules it detects. some sensors I've seen like that can detect methane, CO2, alcohol, etc, but there are others...maybe it's checking for H2S or some other bad smelling molecule....or maybe it just doesn't work lol

That segment on the toilet paper 🧻 hat is worthy of five minute crafts when they actually show a craft that WORKS but is completely impractical and I hope to see it when they inevitably steal your content 😆 10/10

I wonder if the breath detector is programmed to sense gingivitis and not bad breath maybe test it on others to see if it works in a different way

The breath detector may be trying to detect levels of bacteria which is usually what causes truly bad breath.

omg aki I was just planning to rewatch some of your videos then found out you recently uploaded a why japan video!! I'm really happy I get to see your content, you're one of my favorite youtubers omg ilysm

Love the video and keep up the great work aki

i love the amount of effort u put into making the hat, the commercial and the end bit aki this was so funny i loved it

Enjoyed it keep up ur ideas vs the ones that makes you say why!!!

I love your ad so neat. I think I'd use it if I was at a gathering

Loved the deep cut in the intro, you're brilliant

Bro when I say I was on the ground laughing 😂 🤣 Aki plz never change love your content

Woahhhhh here early!! Loved the video Aki! Absolutely love the series, its great as usual. Who wouldn't want that hat?

8:32 the most awkward ad I've ever seen and which i dont wanna skip🤣🤣🤣

This actually made my day thank you : )

love this series

I love the commitment at the end

I just imagine the neighbours going "I don't know WHY!" 😭

Where was that hat when I was sick last week?? The only thing I'd say to add to it is a mini trash can to put the used tissues in. That would make it the best invention ever! no more tissue boxes and trash cans hoarding your desk or nightstand when you're sick anymore! Edit: It also perfect for emotional people, funerals, or the average person that always forgets to refill the toilet paper dispenser in the bathroom (100% me), it's perfect for every occasion!

Outstanding performance Aki you have charisma... Your quite a character you always uplift my spirit when im feeling down...I had a horrible day at work today....Thank you Aki God bless your heart kiddo! 🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭🎃❣️🍭

I kept waiting for the toilet paper hat to snag on something and Aki to dramatically fall as a result lol. Amazing product lol

Thank you for this video Aki, you are so funny 😂😂

I imagine Joey being super supportive & wearing the hat! ❤️

The commercial and ending skit were the best, haha

1:14 dont think about it dont think about it dont think about it

10/10 would buy, would use on the daily, would share it with friends and family, would gift it to friends and family, I love it👍🏻

I love the commercial!

I swear that actually made me hungry!🤪😝🤣 Defective breath checker! Great Fun!

The toilet hat commercial just killed me on the spot!!🤣🤣🤣🤣

That’s so awesome. I would totally buy it as I suffer with haye fever all year round. So proud of you for making it from scratch. Well done you.

The things Aki does for us 😭🥰. Also, Aki doing better than Japanese inventions 👏🏻

I'm watching the video at two times speed and the fast breating out is so funny

Hello Aki! 😁 I hope you have a good day/night!

Aki is the only KZfaqr that will willingly down adobo ingredients just to make a japanese gadget work

Akii you are so funny in a good way ☺

Your toilet paper hat is awesome great job

I was literally waiting for Joey to walk in and go what the f***. At the end.

That Ace Ventura bit was great

it's the dancing at the end for me, Beat Boxing Blueberry Vibes

The toilet paper hat…fkn ingenious 👌🏽👌🏽👌🏽 Coming to Etsy soon? 🤣

It’s worth it just seeing you dancing with it on- gonna wear it for Halloween? Be awesome if it was worn with umbrella shoes, or those shoes that wash clothes as walking, that bib thing & if there was something that’s also a skirt lol

So much chaos energy in this video

🤣🤣This made me laugh after a shi**y ass day thank you dude 🤙🤙

Great job with toilet paper hat also btw 😂

lmfao the toilet paper hat! The design is very human indeed 🤣🤣

I think your toilet paper 🧻 hat is great . I had a really bad cold recently and that would of be perfect 👍

As someone with bad allergies and gets nosebleeds when ever the air gets too dry the toilet paper hat seems useful
