What Is Hatsukokoro?
Hatsukokoro (初心) means “beginner’s mind” or “first heart” in Japanese—a concept from Zen Buddhism about returning to fresh, beginner perspective.
The brand was founded in 2018 in Sakai by a craftsman who left Konosuke to launch independently. Hatsukokoro uses the same Sakai forging network as Konosuke (master smiths + specialized sharpeners + handle makers).
Why Hatsukokoro rose so fast
- Quality at lower price: Comparable to Konosuke at 70-80% of cost
- Aogami Super specialization: Their Kumokage line uses one of the best carbon steels
- Sakai craftsmanship: Same forging tradition
- Modern marketing: Active social media, English documentation
- Knifewear partnership: Distributed by Canada’s largest Japanese knife retailer
Forum perception
On r/chefknives and Japanese forums, Hatsukokoro is described as:
– “Konosuke without the markup”
– “Aogami Super done right”
– “Best new Sakai brand in a decade”

Hatsukokoro Aogami Super Deep-Dive
Aogami Super (青紙スーパー) is one of Japan’s best carbon steels:
– High tungsten content (extreme edge retention)
– High chromium (slightly less rust-prone than Shirogami)
– HRC 64-65 achievable
– Easy to sharpen despite hardness
Why this steel choice matters
Most “carbon steel” Japanese knives use Shirogami or Aogami #1/#2. Aogami Super is the next tier:
– More tungsten = harder grain
– Better edge retention
– Slightly more difficult to forge well
Hatsukokoro’s mastery of Aogami Super differentiates them from competitors.

Common Hatsukokoro Misconceptions
“Hatsukokoro is cheap Konosuke”
No. Hatsukokoro is independent. Different metallurgy choice (more Aogami Super), different design philosophy.
“Hatsukokoro can’t be a top brand because it’s new”
False. Brand age doesn’t equate to quality. Hatsukokoro uses the same Sakai craftsmanship Konosuke does.
“Aogami Super always rusts”
Mostly false. Hatsukokoro’s heat treatment is excellent—rust occurs only with neglect, not normal use.
“Kumokage is just Aogami Super with marketing”
Partially true. The Hatsukokoro brand quality control + Sakai forging consistency justify the markup over generic Aogami Super knives.
Conclusion
Hatsukokoro is the best emerging Japanese knife brand for serious home cooks in the $250-450 range.
Best first Hatsukokoro: Kumokage Aogami Super Gyuto 240mm ($380) — if you’re committed to carbon steel maintenance.
If you want easier maintenance: Issaku SLD ($280) or Hayabusa VG-10 ($220).
For premium investment: Inazuma SG2 ($450).
Hatsukokoro represents the next generation of Sakai craftsmanship—younger, more design-forward, and increasingly preferred by enthusiasts over more established brands.
