Definition: Oshi (推し) is derived from the verb osu (to push/recommend). In modern Japanese slang, it refers to a person, character, or entity that you actively support, promote, and admire. It is the Japanese equivalent of having a ‘bias’ or ‘ultimate favorite,’ but with a significantly deeper layer of financial and emotional commitment.
If you’ve spent any amount of time in Tokyo, you’ve likely seen it. Maybe it’s a coworker with a lanyard covered in pins, or a friend who refuses to eat at a restaurant unless their favorite idol recently visited it. This is the world of Oshi-katsu—or ‘Oshi-activities.’ It isn’t just liking something; it’s an identity.
When I first moved to Japan, I thought my roommate was obsessed with a specific J-pop singer. It wasn’t until I saw her altar—a dedicated shelf space for merchandise, concert DVDs, and photo cards—that I realized this wasn’t a hobby; it was a devotion. She wasn’t just a fan; she was a supporter whose life rhythm was dictated by her Oshi’s schedule.
The Evolution of Oshi: From Secret to Lifestyle
Originally, the term belonged strictly to the underground ‘Idol’ (pop star) subculture. It was the person you ‘pushed’ (voted for) during popularity contests. Today, the term has permeated every corner of Japanese society. You can have an Oshi who is a professional baseball player, a historical figure, a YouTuber, or even a local train operator. It has moved from the shadows into the mainstream, becoming a massive economic driver.
“Oh, you’re going to the concert tonight? Is that your Oshi performing?”
“No, I’m just going for a friend. My Oshi is on hiatus right now, so I’m currently in a state of Oshi-loss.”
Pro-Tip: Don’t mistake Oshi for just being a ‘fan.’ A fan consumes; an Oshi-katsu practitioner invests. If you want to sound like a local, use the term Oshi-katsu to describe the act of supporting your favorite. It’s a very common phrase used to explain why you are buying that third version of the same CD!
Common Mistakes Foreigners Make
The most common error I see non-locals make is applying the term too lightly. If you tell a Japanese person that a random celebrity you saw once is your ‘Oshi,’ they will be confused. Being an Oshi implies a willingness to pay, to attend events, and to ‘spread the word’ (the original meaning of osu). It’s a commitment of time and money, not a fleeting interest.
Also, avoid using it as a direct translation for ‘crush.’ While you can have a romantic attachment, Oshi is usually about admiration and support, not necessarily dating-style longing. Keep it grounded in the ‘fan-to-entity’ dynamic.
Slang Variations You Should Know
- Oshi-katsu (推し活): The activities you do to support your Oshi.
- Oshi-hen (推し変): Changing your ‘Oshi.’ This can be considered a social taboo in strict fandoms!
- Oshi-doko (推しどこ): Asking someone, ‘Who is your Oshi?’
- Oshi-ga-tatooi (推しが尊い): A phrase meaning ‘My Oshi is precious/holy.’ Use this when you feel overwhelmed by your favorite’s talent or charm.
If you’re curious about other ways people express their passions, you might find it helpful to look at how excitement is articulated in Waku Waku: The Japanese Secret to Pure, Childlike Excitement. Understanding this will help you decode the pure joy people feel when they talk about their Oshi.
Lastly, always remember that in Japan, communication is often about the subtext. Just as we learn in Kuuki wo Yomu: The Japanese Art of Reading the Air, your Oshi-katsu journey should be respectful of others’ interests as well. Japan is a society built on shared passions, and finding common ground through Oshi is one of the fastest ways to build friendships here.
