Waka-ru- is a colloquial, elongated, or slightly altered version of the standard verb wakaru (to understand). While standard Japanese emphasizes clarity, waka-ru- often signals a relaxed, somewhat indifferent, or overly casual attitude. It’s frequently used by younger generations to soften the impact of a statement or to express a casual ‘I get it’ without the strict formality of traditional Japanese grammar.
After living in Tokyo for years, you start to notice that the language isn’t just about what is in the textbooks—it’s about the rhythm. When a native speaker says ‘Waka-ruuu’ with a drawn-out vowel, they aren’t just saying they understand. They are injecting personality, weariness, or even a sense of shared exhaustion into the conversation. It is a far cry from the polite ‘Wakarimashita’ you learn in your first Japanese lesson.
In the office, you might hear a junior employee use this in a very specific, low-energy context. It’s not meant to be rude, but it definitely carries a different weight than the standard dictionary definition.

The Cultural Nuance of Elongated Vowels
In Japanese, elongating a vowel at the end of a word like wakaru often acts as a softener. It turns a sharp, definitive statement into something more conversational. However, a major mistake foreigners make is using this ‘slang’ form with superiors. Using ‘Waka-ru-‘ in front of a bucho (department manager) will likely be interpreted as a lack of professionalism or, worse, arrogance.
Junior: “The project deadline has been moved up to tomorrow morning.”
Colleague: “Waka-ru- (sighs)… Let’s just do what we can.”
Notice the resignation? That is the essence of the slang. It’s a way of saying, ‘I understand the gravity of the situation, and I am choosing to handle it with a sense of fatalistic humor.’ For more on how these informal tones fit into the broader spectrum of Japanese communication, take a look at Tsukkomi Meaning: Mastering the Art of Japanese Retort and Comedy, which also relies heavily on these casual speech patterns to land a joke.
Pro-tips for using Waka-ru-:
- Never use it with strangers: It implies a level of intimacy you haven’t earned yet.
- Watch your pitch: If said with a high pitch, it sounds like ‘I get it, I get it, stop talking!’ If said low and flat, it sounds like ‘I understand, but I’m tired.’
- The Gender Factor: It is arguably more common in casual, informal group settings among younger men and women, but traditionally, women might use a slightly different pitch or intonation to sound ‘cute’ or ‘soft.’
Common Mistakes Foreigners Make
The biggest pitfall is the assumption that slang makes you sound like a local. Often, using this style of speech sounds forced if your Japanese proficiency isn’t high enough to support the necessary body language and facial expressions that accompany it. If you sound monotone but use casual slang, you come across as sarcastic, even if you don’t mean to be.
Remember, Japan is a culture where Teinei (politeness) is the default. Deviating from that through slang is a deliberate choice. Use it only when the social air has been cleared for total informality.
