Usage

Sense 1 is extremely common in gaming and collecting culture, where items are graded by rarity (レア, スーパーレア, ウルトラレア). It has spread into general conversation as a casual way to say something is uncommon or special. The Japanese word (めずら)しい covers similar ground but is the standard native word.

Sense 2 is used when ordering steak at restaurants. The doneness scale in Japanese is: レア → ミディアムレア → ミディアム → ウェルダン.
