Short answer: In Japanese, carp is called 鯉 (koi).
- 鯉 (koi) — the general name for the carp family; used for the common carp you catch or see in rivers and ponds.
- 錦鯉 (nishikigoi) — ornamental koi, the fancy patterned varieties kept in ponds and koi farms. The term means 'brocade carp.'
If you’re talking about the edible carp or just saying 'carp' in everyday speech in Japan, you’ll still use 鯉 (koi). The phrase 錦鯉 is reserved for the decorative, museum-quality pond fish.
Helpful phrases:
- この鯉は大きいです。 (Kono koi wa ookii desu.) — This carp is big.
- 錦鯉は美しい模様があります。 (Nishikigoi wa utsukushii moyou ga arimasu.) — Nishikigoi have beautiful patterns.
A few quick notes for context:
- The ornamental koi you see in ponds are usually grouped under the term 錦鯉 (nishikigoi) and there are famous varieties like Kohaku (red and white), Taisho Sanke (Sanke) and Showa Sanshoku (Showa).
- If you’re visiting a pond or garden in Japan, expect to see signs that say 鯉 or 錦鯉 depending on whether they’re referring to any carp or the fancy koi.
Bottom line: when you’re talking about carp in Japan, you’re most often saying koi; if you mean the decorative pond fish, that’s nishikigoi. Tight lines and may your next catch be a koi of distinction! 🎣
