[Easy and Simple!] Birthday Surprise Ideas for Friends (1–10)
A huge giveaway of dagashi (Japanese cheap snacks)

When you were a kid, did you ever think, “I want to buy a ton of snacks and eat them all!”? I bet a lot of people have—but few actually make that childhood dream come true as adults.
So how about giving a friend a big bundle of snacks as a gift? Choosing nostalgic treats—like the cheap candies and snacks you used to eat as a kid—would probably make them really happy.
Before you give the gift, casually do a little research by asking, “What snacks did you like when you were a kid?”
Messages with sticky notes and washi tape
When you’re having a birthday party at home, you can go all out with birthday-themed decorations, but it’s hard to decorate for birthdays at the office, at school, or when meeting friends outside—unless you’ve reserved a whole venue.
So how about using masking tape or sticky notes to spell out “HAPPY BIRTHDAY” on a desk or computer? Masking tape and sticky notes can be stuck on and peeled off without leaving marks, so you can put them up anywhere.
Surprise box

Here’s a surprise idea where the box itself becomes the gift: when you hand over the present, there’s a twist built into the gift box.
Many people use 100-yen shop boxes and wrapping paper to wrap presents.
With just a little extra effort added to those wrapping supplies, you can make a gift that’s even more delightful! For example, you could paste photos on the inside of the box, or nest another box inside—put the main gift in the small inner box, and pack the larger outer box full of sweets.
It’s a surprise that brings double the joy.

Filmed without permission on a friend’s smartphone

It’s a surprise idea with a playful prank vibe: secretly taking photos on your friend’s phone.
When your friend steps away and leaves their phone behind, that’s your chance! Even if the phone is locked, on most models you can still access the camera by swiping on the screen.
Write a congratulatory message on a sketchbook, take some fun group photos, and then put the phone back exactly where it was, acting like nothing happened.
Now, when will your friend notice the pictures…? Can’t wait to find out (lol).
Get a free original ticket

Many of you probably made and gifted things like a “shoulder massage coupon” for your mom or dad when you were kids.
It’s not exactly a shoulder-massage coupon (haha), but how about making and giving an original ticket? An original ticket using photos with your friends would be super cute.
Plus, you can make it with free apps and materials.
If you’re going to do it, making tickets with a specific purpose—like a “Free Juice Coupon” or a “Massage Coupon”—would probably be a hit, too.
Masks for everyone

If you’re getting together with friends to plan a surprise, how about everyone wearing masks and lying in wait for the guest of honor? Even a single mask would be startling, but imagine if everyone there was wearing your face… Just picturing it is fun, right? (lol) You can make the masks with a printer, so print lots using your friend’s favorite face photo! Be sure to take photos of everyone wearing the masks, and don’t forget to capture your friend’s surprised expression the moment they open the door!
100-yen shop balloon decoration

If you’re planning a surprise where you invite your friend and celebrate their birthday, how about decorating the venue? These days, party supplies and decoration items come in a wide variety at 100-yen shops.
Party balloons in particular come in many cute styles! If you have wall space, definitely make use of things like a festive “HAPPY BIRTHDAY” sign and a balloon garland to brighten things up!
