[For Adults] Fun Activities and Hobby Ideas for Rainy Days
You made plans to hang out with a friend, checked the weather forecast for the day, and saw rain…
You might have found your way here because you’re wondering, “Uh, what should we do then?”
In this article, we’ll introduce activities and hobbies you can enjoy at home on a rainy day.
Although the earlier example was “hanging out with a friend,” these ideas are also perfect for spending time solo.
And because the theme is “for adults,” some of them require fairly serious preparation.
But… that’s exactly why these ideas are so rewarding and satisfying!
[For Adults] Fun Activities and Hobby Ideas for Rainy Days (1–10)
Funny senryu

Senryu, which was born in the Edo period, is still loved today in forms like the “Salaryman Senryu.” Unlike haiku, it doesn’t require seasonal words and can be written in colloquial language, which I think is part of its appeal.
How about trying some senryu as a way to pass the time on a rainy day? It’s also fun to read them aloud with friends! The key to senryu is choosing a theme.
It’s recommended to pick clear themes like seasonal topics or social/current events.
Why not enjoy some wordplay that only adults can come up with?
Tarot reading

Fortune-telling can feel mysterious, and you might wonder, “Is there a proper way to do it?” For anyone interested in fortune-telling, tarot reading is highly recommended and perfect for passing the time indoors! In this video, we carefully introduce beginner-friendly methods for tarot reading, including how to shuffle, cut, and flip the cards.
Once you get the hang of tarot and read for your family and friends, they’re sure to love it! It’s also great as a hobby, so be sure to check it out for reference.
board game

When it comes to classic indoor activities you can play with multiple people, board games are probably the go-to choice.
From long-time favorites like shogi, Othello, and The Game of Life to the latest releases, there’s a huge variety of genres out there.
This video introduces a Top 10 selected by board game enthusiasts from among that vast lineup, making it perfect for beginners or anyone interested in board games but unsure which one to buy.
It also features some rare titles, so if you find yourself with some free time, why not give them a try?
Authentic confectionery making

For busy adults, baking can feel like a high hurdle unless there’s a special event, right? Still, many people say that precisely because you can really focus on it, baking is great for relieving stress.
Just following a recipe is fun, but on a rainy day off for adults, it might be nice to let a bit of your personal flair show.
For example, like in the video, making chocolate ice cream with a careful selection of cacao varieties is something you don’t get to try often—highly recommended.
How about savoring the luxury of enjoying something you made all to yourself? Of course, getting together with friends and making it while having fun is great too!
Home izakaya

If rain ruins your plans to go out, how about making your own snacks and turning your home into a cozy izakaya? Whip up some quick and easy pub-style dishes and enjoy your drinks deliciously! Even if you’re not confident in the kitchen, no worries.
Each dish is simple, but making several instead of just one adds volume, gives it that izakaya vibe, and makes it more satisfying.
The slightly stylish presentation that makes everything look tasty is a bonus, too.
You could even invite friends over and cook together!
indoor camping

Let me introduce an “indoor camping” idea that’s perfect for rainy days when you can’t go out and play.
It creates an extraordinary space inside your home and is sure to make even rainy days fun! Pitch a tent indoors and try sleeping in a sleeping bag, cook camp-style meals using outdoor kitchen gear, or change up the lighting—little touches like these can bring a fresh twist to your routine.
For busy adults, it’s also a great way to reset.
Invite some friends over and enjoy an indoor camping experience at home.
Challenge the magic

Magic is something you can perform as a party trick in all kinds of situations once you learn it, right? While using cards or coins is common, wouldn’t it be cool to casually perform magic with everyday items? This video introduces a trick using tissue paper you can find anywhere.
It looks easy enough for beginners to copy, so give it a try.
Using familiar items can also serve as a great communication tool.
Next time someone says, “Show us something,” try performing this trick!
Cardboard crafts for adults

How about some authentic “adult cardboard crafts” you can enjoy indoors? Even if DIY with wood feels intimidating, you can easily give it a try using cardboard, a material close at hand.
In this video, we introduce three amazing items made from cardboard! Believe it or not, you can make a drink station and a vending machine out of cardboard.
The drink station actually dispenses juice and coffee, and the vending machine will vend a drink when you insert money! You’ll also learn how the mechanisms work, so it’s educational too.
Outfit showdown

How about a “styling showdown” as a game that can liven up a rainy day indoors? You can bring your own clothes, or set a budget—like within 5,000 yen per person—buy outfits, and get ready that way.
It might also be fun to have a friend model while you dress them in the outfit you picked and let other friends be the judges.
Your fashion sense will be put to the test, so it’s sure to be thrilling and exciting, with a game-like feel that will definitely deepen your friendships! If you suddenly find yourself with free time and don’t know what to do, give this a try.
three-dimensional paper cutting

Let me introduce a “3D paper cutting” project that’s perfect for passing time on a rainy day.
It’s especially recommended for people who enjoy detailed handiwork or are good with their hands.
Prepare a precision craft knife, a cutting mat, and a thin paper called TANT paper.
Cutting out fine patterns requires patience and concentration, so it’s also ideal if you want to immerse yourself in something and relieve stress.
To add a three-dimensional effect, we use pearl-sized beads.
Once you’ve created the rounded shapes, glue the paper layers together.
It’s a project that gives a great sense of accomplishment, so it’s also great as a hobby!
