The Japanese verbal noun '規制 (きせい)' refers to 'regulation' or 'control'. It is commonly used in contexts involving rules, restrictions, or measures imposed by authorities to manage or limit certain activities. For example: The government imposed new regulations「政府は新しい規制を設けた」(せいふはあたらしいきせいをもうけた). There are strict regulations on this product「この製品には厳しい規制がある」(このせいひんにはきびしいきせいがある). The word can also be used in broader contexts, such as environmental regulations or financial controls, and often carries a formal or official tone.
