平和
へいわ
heiwa
= peace / tranquility / a state free from conflict or disturbance
Heiwa means peace in Japanese, but it resonates with particular depth in a country that enshrined pacifism into its constitution after World War II. For Japanese speakers, heiwa is not an abstract political concept but a lived aspiration shaped by specific historical memory — the words 広島 (Hiroshima) and 長崎 (Nagasaki) are inseparable from how the word is felt.
Heiwa (平和) is a noun and na-adjective meaning ‘peace,’ ‘tranquility,’ or ‘a state free from war, conflict, or disturbance.’ As a na-adjective, 平和な (heiwa na) describes something peaceful: 平和な生活 (heiwa na seikatsu, a peaceful life), 平和な時代 (heiwa na jidai, a peaceful era). As a noun: 平和を守る (heiwa wo mamoru, to protect peace), 世界平和 (sekai heiwa, world peace), 平和主義 (heiwa shugi, pacifism). Heiwa can describe both the large scale (no war between nations) and the small scale (a peaceful household, a quiet Sunday). The adjective form 平和的 (heiwa-teki, peaceful/pacifistic) is used in political and diplomatic contexts.
Japan’s Article 9 of the Constitution (憲法第九条, kenpo daiku-jou) — which renounces war and forbids maintaining war potential — is known as the 平和条項 (heiwa jyokou, peace clause) and has been central to Japanese political debate since 1947. The phrase 平和憲法 (heiwa kenpou, peace constitution) reflects how deeply heiwa is embedded in Japan’s postwar national identity. In casual conversation, 平和だ (heiwa da) or 平和だね (heiwa da ne) can simply mean ‘things are calm / it’s quiet here’ — showing how the word scales from geopolitics to everyday tranquility.
平和 is written with 平 (hei/taira, flat/equal/level/peaceful) and 和 (wa, harmony/Japan/peaceful agreement). 平 appears in 平等 (byoudou, equality), 平均 (heikin, average), and 平静 (heisei — incidentally, the name of the 1989–2019 imperial era). 和 is the classical word for Japan itself (大和, Yamato) and appears in 和食 (washoku, Japanese food), 和室 (washitsu, Japanese-style room), and 調和 (chouwa, harmony). Together, 平和 captures both the flatness of undisturbed terrain and the harmonious agreement between parties.
Everyday use

Formal / Cultural context
広島は世界平和の象徴として、その記憶を語り継いでいます。
Hiroshima wa sekai heiwa no shouchou toshite, sono kioku wo kataritsuide imasu.
Hiroshima continues to pass on its memories as a symbol of world peace.
Japan’s constitutional pacifism has made heiwa one of the most politically charged and emotionally resonant words in modern Japanese. The 1947 Constitution’s Article 9 — drafted during the American occupation and retained ever since — declares that ‘the Japanese people forever renounce war as a sovereign right of the nation.’ This constitutional commitment to heiwa has shaped Japan’s post-war identity, its defense policy, and ongoing political debates about whether and how to revise the constitution. Peace museums (平和記念館, heiwa kinenkan) in Hiroshima and Nagasaki draw millions of visitors annually and are central to Japanese civic education on the consequences of war.
At the everyday cultural level, heiwa carries a gentle, domestic meaning alongside its weighty political one. The expression 平和な家庭 (heiwa na katei, a peaceful household / harmonious family) is a common aspiration in Japanese culture, reflecting the value placed on family harmony. The phrase 平和ボケ (heiwa-boke, peace-complacent / naive because of long peace) — sometimes used critically about Japanese people who have grown unaware of security risks due to decades of relative safety — shows how the word has generated its own self-reflexive discourse about whether peace produces preparedness or complacency.
