I have read some topics about usage of では on the internet, like で for places, means, tools and は to mark the subject, argument,... However, I can't apply those to explain meaning of では in this sentence


As I understand, 東京電力 is Tokyo electric company and they are the one (the subject) explaining the reason why electric price is going up. Why do the writer add not only は but also で here?

は does not mark the subject; it marks the topic. The topic can serve any other function in the sentence. Often the topic is the subject. But, it can also be the object (direct/indirect) of the verb. は also can be used to mark contrast.

Notice, the topic is actually 値上げ, the increase in price.

With 東京電力では, the use of は adds a sense of contrast. Various other electric companies might explain the increase in prices in other ways but here at Tokyo Electric the explanation is that which was quoted.

  • I understand what you said. But the main question I want to ask here is the role of で. I mean, で in this sentence is not pointing a place that something happens. or a means of transport, right? It confuses me at this point

    @Mihara I'm not sure how native speakers would construe it. But as I read it, an explanation was given at a certain place and that place happens to be Tokyo Electric. This is not an uncommon sentence structure in Japanese where で is used to mark the source of the information (here explanation).
