S Legend — The $1.8 Million Koi
S Legend is not just the most expensive koi fish ever sold — she is the benchmark against which all championship koi are measured. Bred by Sakai Fish Farm in Hiroshima Prefecture, Japan, she was a female Kohaku whose combination of physical attributes was considered near-perfect by the world’s most experienced koi judges.
What made S Legend worth $1.8 million comes down to five factors operating simultaneously at the highest possible level:
Skin quality — the white (shiroji) base was described as pure snow, with a depth and clarity rarely seen even among championship koi
Hi (red) quality — intense, uniform crimson red with clean, defined edges and no bleeding or fading
Pattern balance — the red markings were distributed across the body in a way judges considered aesthetically ideal — neither too sparse nor too dense
Body conformation — torpedo-shaped, symmetrical, well-proportioned for her size
Bloodline — Sakai Fish Farm is widely considered the greatest Kohaku breeder in the world; their fish carry a premium simply for the pedigree
The tragic postscript to S Legend’s story is that she died shortly after being purchased, reportedly due to stress from international transport. Her buyer, Dr. Tomoharu Aoki, had planned to breed her. The loss highlighted the risks involved in transporting elite koi across continents — even with expert handlers.
Understanding what drives koi prices helps collectors make better decisions — whether buying a ₱2,000 fish for a backyard pond or bidding on a six-figure show champion. The same criteria apply at every level; what changes is the degree of perfection.
🎨
Skin & Color Quality
The white base must be pure snow-white with no yellowing or grey. Red hi must be intense, uniform, and clean-edged. Both qualities deteriorate with stress, poor water, or age.
🔷
Pattern Balance
Markings should be distributed harmoniously across the body — neither too concentrated nor too sparse. The head, shoulder, and tail areas all need to work together visually.
🐟
Body Conformation
A torpedo-shaped body with no deformities, even fin placement, and good depth at the shoulder. Body shape is one of the first things judges assess at a koi show.
🧬
Bloodline & Breeder
Sakai, Dainichi, Marudo, and Omosako are among the most prestigious Kohaku breeders. Their fish command a premium because the bloodline produces consistent quality across generations.
📏
Size for Age
Large, well-grown koi demonstrate good genetics and husbandry. A 70cm+ Kohaku commands far more than a 40cm specimen of identical pattern quality.
✨
Lustre & Presence
The Japanese concept of “showa” — the visual impact a koi has from a distance — is difficult to define but immediately felt. The best koi stop you in your tracks.

Koi Fish Prices in the Philippines
In the Philippines, koi fish are widely available at different price points depending on source and quality. Local farm-bred koi are affordable and healthy; Japanese imports command a significant premium but bring elite genetics and show quality.
The most expensive koi fish ever sold is S Legend, a female Kohaku (red and white) koi bred by Sakai Fish Farm in Japan. She was sold at auction in Hiroshima in October 2018 for approximately $1.8 million USD (£1.4 million / ₱100 million). The buyer was Dr. Tomoharu Aoki, a prominent Japanese koi breeder.
How much does a koi fish cost?
+
Koi fish prices range enormously. Common pet-store koi cost $10–$50 USD (₱500–₱2,800). Mid-grade hobbyist koi cost $50–$300 (₱2,800–₱17,000). Show-quality koi from reputable breeders cost $1,500–$10,000+. The world record is $1.8 million for S Legend. In the Philippines, koi typically range from ₱500 to ₱50,000+ depending on size, quality, and source.
Who bought the $1.8 million koi fish?
+
The $1.8 million koi fish, S Legend, was purchased by Dr. Tomoharu Aoki, a prominent Japanese koi breeder and collector. She was sold at the Sakai Fish Farm auction in Hiroshima, Japan in October 2018.
What type of koi is the most expensive?
+
Kohaku koi — white body with red markings — are consistently the most expensive variety at the elite level. S Legend, the world record holder at $1.8 million, was a Kohaku. Gosanke varieties (Kohaku, Sanke, and Showa) dominate top auction prices. The quality of the specific fish matters far more than variety alone.
What is the rarest koi fish?
+
Ki Utsuri (yellow and black koi) are among the rarest varieties, with very few high-quality specimens available. Ginrin metallic koi with perfect shimmer are also rare. The Yamabuki Ogon with a perfectly uniform metallic gold finish and zero blemishes is considered one of the rarest to find at top show quality.
How much is koi fish in the Philippines?
+
In the Philippines, koi fish range from ₱300–₱1,500 for common pet-shop varieties, ₱1,500–₱8,000 for mid-grade farm koi, and ₱8,000–₱30,000 for quality local breeder stock. Japanese imports start around ₱30,000 and can reach ₱500,000+ for show-grade specimens. Giobel Koi Center offers koi starting from ₱1,500.
What makes a koi fish valuable?
+
The key factors are: body conformation (torpedo shape, no deformities), skin quality (pure white base, intense red hi), pattern balance and symmetry, color intensity, size for age, breed and bloodline (Sakai Farm, Dainichi, and other elite breeders command premiums), and overall visual presence — what Japanese judges call “showa.”
Are expensive koi fish a good investment?
+
Top-quality koi from elite Japanese breeders can appreciate in value, particularly Gosanke with championship pedigree. However, koi require expert care and significant ongoing expense. Most serious collectors keep koi for the passion rather than as a primary financial investment. The koi market is also niche and illiquid compared to traditional assets.
