Grammar JLPT Level N3 - Lesson 7

In order to say that one thing is 'based on' another in Japanese, the expression に基(もと)づいて will be used. This is a combination of the case marking particle に, the う - Verb, 基(もと)づく 'to originate from', and the conjunction particle て. This expression regularly highlights some kind of judgement/conclusion that the speaker has made, using (A) as their base.
To use に基(もと)づいて, put the noun (or noun phrase) that you would like to identify as a 'basis' before に基(もと)づいて, and then express your judgment/conclusion in part (B) of the sentence.

• クライアントの指示(しじ)に基(もと)づいて、編集(へんしゅう)をしておきました。
  I have edited this based on the client's instructions. (Edited in advance, assuming that would be the client's wishes)
• 以前(いぜん)成功(せいこう)した計画(けいかく)に基(もと)づいて、新(あたら)しい計画(けいかく)を立(た)てようと思(おも)っています。
  I am thinking of making a new plan based on the previous successful plan.

Alternatively, the past form of 基(もと)づく may be used when connected directly to a second noun. (A) に基(もと)づいた (B) directly expresses that (B) is based on (A).

• 私(わたし)は実話(じつわ)に基(もと)づいた映画(えいが)が好(す)きです。
