Introduction
Welcome back! In our last lesson, we focused on understanding warnings by learning the kanji for "prohibition" (禁止, kinshi) and "caution" (注意, chūi). We specifically noted that the first character in kinshi, 禁 (kin), means "forbidden."
This lesson builds directly on that knowledge to help you recognize one of the most common signs in Japan: 禁煙 (kin'en), for "no smoking." We will also cover another vital safety sign, 非常口 (hijōguchi), meaning "emergency exit." Being able to spot these signs instantly is a crucial skill for navigating public spaces, from restaurants and hotels to train stations.
1. No Smoking: 禁煙 (kin'en)
As promised, let's start with the word for "no smoking." Its structure is a great example of how knowing individual kanji can help you decipher new words.
The word 禁煙 (kin'en) is composed of two kanji:
- 禁 (kin): This is the character for "forbidden" or "prohibited" that you learned from 禁止 (kinshi).
- 煙 (en): This character means "smoke."
So, 禁煙 (kin'en) literally translates to "forbidden smoke," or simply, "No Smoking."
You will see this sign everywhere. It's often accompanied by the universal "no smoking" symbol, making it easy to recognize.

To see this word in the context of other related signs, please read the following section from the resource we've used before.

This article, 'The Most Useful Kanji for Tourists Traveling in Japan,' places 禁煙 (kin'en) in the context of dining out. It also introduces the opposite term, which is useful to know.
Please read the section titled 'Eating and Drinking Kanji.' Focus on the explanation for 禁煙 (kin-en) and its counterpart, 喫煙 (kitsu-en), which means 'smoking allowed.'
As you read, you learned that restaurants often have both smoking (喫煙, kitsu-en) and non-smoking (禁煙, kin'en) sections. Recognizing the 禁 character is your key to ensuring you're seated in the area you prefer.
2. Emergency Exit: 非常口 (hijōguchi)
Next up is a sign that's critical for your safety: the emergency exit. In Japan, these signs are standardized with a green background and a "running man" pictogram, but knowing the kanji is still very important.
The word is 非常口 (hijōguchi). Let's break it down:
- 非常 (hijō): This compound word means "emergency."
- 非 (hi) means "non-" or "un-".
- 常 (jō) means "normal" or "usual."
- Together, they literally mean "un-usual," which translates to "emergency."
- 口 (guchi): This character means "mouth" or "opening." You've likely seen it before in words like 入口 (iriguchi) for "entrance" and 出口 (deguchi) for "exit." It signifies a point of passage.
Putting it all together, 非常口 (hijōguchi) means "emergency opening" or "emergency exit."
Here is what the sign typically looks like.

To reinforce this, let's look at the same resource again, this time focusing on how 非常口 relates to other "exit" and "entrance" signs.

This reading will help you contextualize 非常口 (hijōguchi) by showing it alongside the more common entrance and exit signs you've already encountered.
Please read the section titled 'Kanji for Entering/Exiting.' Notice how the character 口 (guchi) is the common element in all three words: 入口 (iriguchi), 出口 (deguchi), and 非常口 (hijōguchi).
By recognizing the compound 非常 (hijō) for "emergency" and the character 口 (guchi) for "exit," you can confidently identify these crucial safety signs, even if other visual cues are absent.
Conclusion
Excellent work! In this lesson, you've added two of the most important public signs to your vocabulary. By leveraging your previous knowledge and breaking down new words, you're building a solid foundation for reading essential kanji during your trip.
Key Takeaways:
- 禁煙 (kin'en) means No Smoking. Remember the formula: 禁 (forbidden) + 煙 (smoke).
- 非常口 (hijōguchi) means Emergency Exit. Remember the formula: 非常 (emergency) + 口 (exit).
- Both signs often use universal pictograms (the crossed-out cigarette and the green running man), but recognizing the kanji is a reliable skill that will serve you well.
