Formal Ways to Say “Optional” in Japanese

Let’s start with the formal expressions for “optional” in Japanese. These phrases are commonly used in official contexts, professional settings, or polite conversations.

  1. 自由選択 (じゆうせんたく, jiyuu sentaku): This phrase translates to “free choice” and is frequently used to indicate something as optional. For instance, you might encounter it on forms or surveys asking for optional information, where it would be written as “任意” (にんい, ninni).
  2. 任意 (にんい, ninni): This term is often used to express the idea of “optional” or “voluntary.” It can be used in formal contexts, such as when referring to optional courses or programs.
  3. 自発 (じはつ, jihatsu): While this term focuses more on the aspect of voluntary action, it can also imply that something is optional. It is often used when describing activities or behaviors done by personal choice.

Informal Ways to Say “Optional” in Japanese

In informal settings or casual conversations, Japanese speakers often use different expressions to convey the concept of “optional.” These expressions are commonly used among friends, colleagues, or in everyday situations.

  1. 好きにする (すきにする, suki ni suru): This phrase literally means “to do as one likes” and is typically used in a casual setting to indicate that something is optional or up to personal preference.
  2. やりたいようにする (やりたいようにする, yaritai you ni suru): This expression conveys the idea of doing something the way you want or feel like. It implies that a particular action is optional and not mandatory.
  3. 自由 (じゆう, jiyuu): While “自由” mostly means “freedom,” it can also imply that something is optional. In informal conversations, it can be used to express the concept of “optional” or “up to one’s discretion.”

Regional Variations

Japanese is spoken not only in Japan but also in various regions around the world. Although the fundamental expressions for “optional” remain the same, there can be some regional variations in vocabulary and intonation. Here are a couple of examples:

Kansai Dialect (関西弁): In the Kansai region, people often use the word “えらべる” (eraberu), which means “to be able to choose” or “to have a choice.” It is a casual way to express that something is optional. For instance, you might hear locals say, “それはえらべるから、自由やな” (Sore wa eraberu kara, jiyuu ya na), meaning “That’s optional, so it’s up to you.”

Tōhoku Dialect (東北弁): In the Tōhoku region, the phrase “好きなんて” (suki nante) is often used to convey the sense of “optional.” It is an informal expression that means “if you like” or “if you want.” Locals might say, “好きなんてやったらいいやんけ” (Suki nante yattara ii yan ke), which roughly translates to “You can do it if you want.”

Summary

Expressing the concept of “optional” in Japanese requires understanding different expressions based on formality and context. In formal settings, phrases like “自由選択” (jiyuu sentaku) or “任意” (ninni) are commonly used. On the other hand, in informal situations, expressions like “好きにする” (suki ni suru), “やりたいようにする” (yaritai you ni suru), or “自由” (jiyuu) convey the idea of something being optional.

Additionally, while Japanese dialects may have slight regional variations, the fundamental meaning and usage of “optional” expressions generally remain the same. In the Kansai region, “えらべる” (eraberu) is often used, and in the Tōhoku region, “好きなんて” (suki nante) is a common expression.
