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.

When making class T-shirts for sports festivals or cultural festivals, many people also add a name on the back.

Speaking of back names, the classic style is to put a name above the jersey number.

There are surely many who want matching back names that pair up with close friends, too!

In this article, we’ll introduce ideas for paired back names that friends can use together.

Use them as inspiration to create class T-shirts that will make lasting memories.

Back-of-shirt nickname pairs for friends. Recommended class-T shirt ideas (21–30)

___ people

“XX-min” is slang referring to people who belong to a specific online community, with many variants like “net-min” (internet folks) or “Yahoo Comments-min.” Bringing this culture into your class T-shirts for the sports festival instantly boosts both individuality and team spirit.

For example, using labels like “All-out-min,” “Latecomer-min,” or your homeroom teacher’s surname can humorously express your class’s character and cheerfulness, giving everyone something to rally around.

Try these net-culture-inspired nameplates on the back to make your sports festival even more fun.

“I wuv you, _” (a cute/childlike way of saying “I like/love _”)

“Chuki” is a youthful, baby-talk-style way of saying “suki” (I like/love it).

If you put “XX chuki~” on your class T-shirt for the sports festival, it makes for the ultimate back-name that’s both cute and funny! Phrases like “Victory chuki~,” “Muscles chuki~,” or “Class X chuki~” let you hype your team’s favorites in a sweet, cutesy tone—perfectly calculated and sure to grab attention.

It loosely yet clearly conveys your class spirit and key selling points.

Why not let a breezy, adorable “XX chuki~” drift through the excitement of the sports festival?

Angel/Demon

There’s that “angel character” and “little devil character” vibe, right? On YOASOBI’s stage at the 2023 Red and White Song Battle (Kōhaku Uta Gassen), Kanna Hashimoto and Ano performed together, and people were buzzing about them as an angel and a devil.

So if you have a friend whose personality is the opposite of yours, try putting “angel” and “devil” in your back names.

It might feel more fitting to let the friends around you decide who’s the angel and who’s the devil rather than deciding it yourselves!

Circuit OFF / Circuit ON

Wear phrases that clearly show you’re a pair, and make your relationship stand out.

It’s a good idea to use a shared word and then line up contrasting terms like “ON” and “OFF” to signal that it’s a pair phrase.

Even if “circuit on” and “circuit off” seem puzzling at first glance, they can feel like a private code between the two of you, projecting trust.

With a slightly twisted expression that draws attention, you can embed your mutual trust within it—a simple-looking yet sophisticated call-and-response style phrase.

“Oshi-men” is short for “the member you support,” and it’s a term often used by idol fans.

“Eternal Oshare-men” means “a member who is eternally supported,” in other words, it expresses mutual affection—perfect as a back-name design.

Isn’t it a great idea to match with a dear friend you could call a bestie? Especially with friends who love idols or have their own oshi, it could be a fun way to feel deeply connected.

Adding non-text elements like arrows or heart marks is also recommended.
