[Class T-Shirt] Recommended Back Name Ideas for Class T-Shirts at the School Culture Festival

10 years as a kindergarten teacher / elementary school teacher / junior and senior high school teacher / childminderkepiko
Graduated from Kunitachi College of Music, Faculty of Music (now: Department of Music Culture and Education, Early Childhood Music Education major). In elementary school, my homeroom teacher was Jun Kusaba, a game researcher. After graduating from university, I worked as a kindergarten teacher for 10 years and as an after-school childcare instructor for 7 years, then took a position as a music teacher at an international school in Singapore. In addition to music education, I engaged in activities that introduced Japanese culture, traditional games, and recreational activities, working with many children. Later, through freelance writing, planning, and editing at Shogakukan, I met many delightful adults and experienced the joy of communicating and sharing. Drawing on the perspective cultivated in the field of education and my experience as an editor, I provide practical information with an emphasis on both input and output, mainly in areas related to music and children. My hobbies include instruments, singing, handicrafts, toys, drawing, traditional games, the outdoors, and books. My special skill is spinning-top tricks.

At school culture festivals, it’s common for each class to make matching T-shirts.

Recently popular “back names” actually originated from sports uniforms—it’s the part where the player’s name goes.

Here, we’re sharing lots of ideas for those back names.

Of course, you can simply put your name, but adding a funny one-liner is also recommended.

Use these ideas as inspiration to come up with fun back names that will liven up your culture festival!

tofu mental; overly sensitive/fragile mindset (like “having a fragile heart/mentality”)

The term “tofu mental” refers to someone as fragile as tofu—someone who gets easily depressed by even minor stress.

Incidentally, the original source is said to be a scene from the anime Yu-Gi-Oh! Duel Monsters, where Yami Yugi becomes utterly dejected after losing a game.

Used self-deprecatingly by the person themselves, this phrase can create a humorous vibe.

It might also be funny if someone who appears mentally tough to anyone looking on uses this as a name on their back, creating a gag that just begs for a witty retort.

#◯◯ addiction

This phrase uses the concept of an addiction—something you can’t live without—to showcase what’s important to you.

By combining a friend’s or partner’s name with “addiction,” you can strongly convey deep trust and affection for that person.

It’s also a great idea to use it as a pair of phrases you say to each other, evoking an image of mutual support.

Notice the hashtag format as well: it seems easy to use not only as the main phrase but also as an accent.

Overwhelming ◯◯

These are phrases that highlight how unique members come together and collaborate toward an event.

By using the shared motif of “overwhelming,” you can emphasize individuality while also conveying team unity.

After “overwhelming,” add a short phrase that captures each member’s personality to showcase who they are.

It’s fine to choose your own phrase, but having others choose one for you could also demonstrate the trust among team members.

Character name

Let’s showcase the team’s unity and trust by featuring shared manga or anime characters on your backs.

It might be clearer if you choose characters that convey each person’s individuality.

You can unify the work you pick, or set a theme like “red” or “protagonists” and choose characters from there—that sounds fun, too.

The choice of character itself reflects individuality, so let’s value each person’s creativity.

It’s also recommended to draw closely connected characters as a pair to highlight your bond.

Grade 1 ○○

“Number One in the Grade at ___” is a handy phrase when you want a jokey, meme-like vibe.

It’s like putting a nickname on your back that says “self-proclaimed ___,” and the funny part is how you’re bragging about how amazing you are.

Beyond writing things that show off your strengths, like “Number One Most Popular in the Grade” or “Number One Singing Ability in the Grade,” using self-deprecating lines like “Number One Troublemaker in the Grade” or “Number One Hates Studying in the Grade” will probably land well too (lol).

If you can’t think of something yourself, try asking people around you and come up with a fun phrase together!

Someone who thrives on praise

A phrase I’d like to introduce as something that gives a comical impression—or perhaps creates a warm atmosphere—is “I’m the type who thrives on praise.” You hear it a lot, right? It means “I grow more when I’m praised than when I’m scolded.” Whether that’s really true or not aside, if someone keeps this phrase in mind and gives you praise, you’ll probably enjoy the school festival with a warm feeling.

And of course, if you’re someone who does thrive on praise, feel free to choose this one!

XX is oxygen.

Sometimes people say “___ is oxygen” to express that their favorite actor or idol is absolutely essential to them.

It might usually feel a bit embarrassing to shout your love from the rooftops, but since a school festival is a special occasion, why not go all out and be open about it? Beyond celebrities, funny back names like “Chocolate and potato chips are oxygen” could be a hit, too.

Take this chance to show everyone what you love to the fullest!
