[For Adults] Make the Most of Your Free Time! Boredom-Busting Ideas (1–10)
Studying for a certification

If you want to make good use of your free time, how about studying for a certification? Having a certification never hurts, and it might become a useful skill when changing jobs.
“Certification” might sound a bit formal, but these days there are ones you can easily earn from home, and there are plenty not only for business but also for hobbies and general knowledge.
Believe it or not, some can be obtained in just one day! The bar isn’t that high, so when you find some spare time, try using it to upgrade your skills!
Watch movies, dramas, and anime

In our busy daily lives, it’s not easy to carve out time to watch movies, dramas, or anime.
But during your free time, they can be the perfect companion! Take this opportunity to catch up on shows you’ve recorded but haven’t watched yet, or binge the latest hits on streaming services.
If you keep up with popular titles, you can get excited about them with friends who’ve seen the same things, and they might even help you build new connections.
It’s also fun to turn off the lights, get some popcorn and a drink, and recreate a movie theater vibe at home!
Coloring book

When you think of coloring books, you might associate them with children’s play.
But there are actually many coloring books made for adults, and they’re quite popular—some people even make a hobby of them.
As adults, we can patiently fill in intricate designs, and instead of just coloring one shade evenly, we can create depth with light and dark tones, make things look three-dimensional, or add playful touches with gradients—there are lots of ways to enjoy it.
Adult coloring books are even available at 100-yen shops, so they’re easy on the wallet.
Why not take this opportunity to give it a try? It’s perfect for passing the time!
to clean

One way to make good use of your free time is cleaning.
Even if you tidy your room, there are surprisingly many spots you feel you really ought to clean—like the bathroom walls, the sink in the washroom, and the kitchen sink.
So if you have the time, take the plunge and clean the places you don’t normally get to! Lots of people share time-saving cleaning tools and ideas on video sites and social media.
If you copy their methods, you might find things become sparkling clean surprisingly easily.
Once you know how, the mental hurdle to cleaning will feel lower, so try using your spare time for cleaning!
DIY

It can be hard to find exactly what you want among ready-made products.
That’s when DIY is worth a try—and it’s perfect for your free time! When you hear “DIY,” you might picture buying lumber, gathering tools, and taking on a big project.
While those kinds of DIY projects are certainly common, there are also easy ones—like simply gluing together items from a 100-yen shop—or projects that use wood and tools but can be finished in an hour.
Ideas like these are fun even for beginners, so take this opportunity to give DIY a try!
Play smartphone games

Smartphone games you can play on your phone—chances are, everyone has tried them at least once.
There are all kinds of mobile games: puzzle games, shooters, story-driven RPGs, action games, and more.
That’s exactly why they’re perfect for killing time! Just download and you can start playing right away.
While many have in-app purchases, most let you play the game itself for free.
Why not find a mobile game that fits your mood and give it a try in your spare moments?
Yoga

Yoga helps you get healthier while relaxing.
It’s said to offer many benefits, such as boosting immunity, improving circulation and posture, aiding recovery from fatigue, and supporting weight loss.
It’s especially popular among women—many of you may have tried going to a yoga studio.
With a yoga mat and comfortable clothing, you can easily start practicing at home.
There are plenty of yoga pose videos available for free online, so try following along to begin.
If you want to make good use of your spare time, why not try yoga to correct body misalignment and improve your overall condition?
Read books and manga

Want to kill some time? How about reading a book or manga.
Novels take a bit longer, but they’re fun because they let your imagination run.
Manga, on the other hand, reads quickly, so if you spend a day on it, it’s not impossible to binge through an entire series.
You can pick up something completely unfamiliar, or try finding and reading the original work behind one of your favorite movies or TV shows.
Even if the main plot is the same, there are often episodes you didn’t know about, so it’s a great way to deepen your knowledge of what you love.
resin craft

You often see accessories and art made with resin, don’t you? Aren’t you curious how they’re made? Resin is a type of plastic, and there are several kinds: epoxy resin, which hardens when two liquids are mixed; UV resin, which cures under ultraviolet light; and LED resin, which cures under LED light.
Which one you use is up to you, but UV resin is commonly found at 100-yen shops, so it might be easier for beginners to start with.
First, try pouring resin and parts like beads into a silicone mold and let it cure.
With resin, you can make almost anything depending on your ideas, so give it a try in your free time!
Draw a picture

How about trying to draw during your free time? That said, there might be more people than you’d expect who aren’t confident at drawing.
First of all, it’s hard to know what to draw, right? I think it’s fine to draw whatever comes to mind, like the scene you’re looking at right now or a favorite anime character.
What’s important is to “draw with a finished image in mind.” If you start drawing without much thought, you’ll quickly find your hand stopping.
But if you decide on the finished result beforehand, it becomes clear what you need to draw, so you can keep going without hesitation.
Of course, it can also be a lot of fun to use techniques that let you express yourself freely, like abstract art!
