How to Say “Suspicious” in Japanese: Formal and Informal Ways

Gaining the ability to express oneself in different languages opens up a world of possibilities for communication and understanding. If you are learning Japanese, it’s indeed helpful to know how to convey the idea of “suspicious” in various contexts – from formal situations to casual conversations. In this guide, we will explore the different ways to express “suspicious” in Japanese, providing tips, examples, and even regional variations. So, let’s dive in!

Formal Usage:

In formal situations, such as business meetings, interviews, or official correspondence, it’s crucial to use appropriate language. Here are a few phrases you can rely on to express “suspicious” formally:

1. 1. Ayashii (怪しい): This is the most straightforward and commonly used term for “suspicious” in Japanese. While it can be used in both formal and informal situations, it remains appropriate for formal contexts as well. For example:
   

   「その取引は少し怪しいです。」
   Translation: “That transaction seems a bit suspicious.”

   This phrase works well in professional settings and is widely understood.

2. 2. Fūi (不意): This term carries a connotation of being “unforeseen” or “unexpected,” often leading to suspicious feelings. It is suitable for expressing suspicion in a more nuanced way without directly labeling something as outright suspicious. For example:
   

   「彼の行動にはちょっとした不意を感じます。」
   Translation: “I sense a hint of suspicion in his actions.”

   This phrase allows you to convey suspicion politely and delicately.

3. 3. Ushinawareta (失われた): While not directly translating to “suspicious,” this word means “lost” or “missing.” It can be employed when discussing a situation that raises doubts or involves missing information, potentially implying suspicion. For example:
   

   「この契約の詳細はなくなってしまったようです。」
   Translation: “It seems the details of this contract have gone missing.”

   This usage suggests suspicion indirectly and allows for a professional tone.

Informal Usage:

In casual conversations or when expressing suspicion among friends, family, or acquaintances, you might opt for more colloquial expressions. Here are a few ways to convey “suspicious” informally:

1. 1. Ayashii (怪しい): As mentioned earlier, “ayashii” is commonly used across various registers. It works well informally too. For example:
   

   「この人、ちょっと怪しいと思わない？」
   Translation: “Don’t you think this person looks a little suspicious?”

   Feel free to use this term casually in conversations with friends.

2. 2. Aku (アク): This term is derived from the English word “ac” and has become popular slang used among Japanese youth. It carries a similar meaning to “suspicious.” For example:
   

   「彼の言っていること、アクじゃね？」
   Translation: “What he’s saying, doesn’t it sound suspicious?”

   You can use this term to express informality and connect with younger Japanese individuals.

3. 3. Nigeteru (逃げてる): This phrase literally means “running away” but can also be used to express suspicion. It implies someone or something is avoiding or evading something, which can be suspicious behavior. For example:
   

   「彼、最近逃げてるって気がするんだよね。」
   Translation: “I feel like he’s been acting suspiciously lately.”

   This informal expression is suitable for friendly conversations.

Additional Tips:

Now that you know the formal and informal ways to say “suspicious” in Japanese, here are some additional tips to enhance your understanding:
