To state what something or someone is known for, the phrase ～は～で有名(ゆうめい) is commonly employed. This construction consists of the topic particle は, the particle で indicating a reason or cause, and 有名(ゆうめい), which can act as either a noun or a な-Adjective.

～は～で有名 generally translates to '(A) is famous for (B)'. More literally, it conveys the meaning 'Regarding (A), by means of (B), it is famous'. Here is a simple breakdown of its components:

(A) は - Marks (A) as the topic of the sentence.

(B) で - Indicates (B) as the reason or cause for the fame.

有名(ゆうめい)だ - Is well-known/famous.

• 私のおばあちゃんは料理(りょうり)が上手(じょうず)なことで有名(ゆうめい)です。
  My grandmother is famous for being a great cook.
• あのラーメン屋(や)はスープがおいしいことで有名(ゆうめい)です。

• 神戸(こうべ)は牛肉(ぎゅうにく)で有名(ゆうめい)です。

Note that in many of the sentences above, こと (or の) comes before で有名(ゆうめい). This is standard when the reason for being famous is a whole clause or action, rather than just a single noun.
