What this solves
Three high-value souvenirs tourists get scammed on: matcha (ceremonial vs culinary pricing, often labeled wrong), wagyu (only specific brands are legit), and Japanese knives (steel grade affects price 5x). Generic travel sites don't explain the difference between VG-10, SG2, R2, and Aogami #2.

How to read results
- Matcha ceremonial: shade-grown, ground with stone, vivid emerald. Should be slightly sweet, very umami. High quality comes from Uji (Kyoto) or Nishio (Aichi). 20g ganha is ¥1,500-3,000.
- Matcha culinary: duller green, more bitter, used in cooking or lattes. ¥1,000-1,500 / 100g.
- Wagyu A5: highest yield, highest marbling. Not always ideal — extremely fatty. A4 is often better balance for non-Japanese palates.
- BMS score 8+: high marbling. Score 5 = standard, 12 = exceptional.
- Knife VG-10: standard stainless, HRC 60-62, easiest to maintain. ¥10,000-25,000.
- Knife R2 / SG2: powdered steel, harder (HRC 62-64). ¥25,000-50,000.
- Knife Aogami #2 (Blue 2): carbon steel, traditional, needs care. HRC 62-63. ¥20,000-60,000.
Limitations
Reference for 2026. Aogami knives must be oil-rubbed to prevent rust. R2 knives are not for first-time knife owners. Matcha quality also depends on the season — first harvest (Ichibancha) is premium.
FAQ
Can I bring a Japanese knife home?
Yes, in checked luggage. Pack it well — wrap in cloth + box. Some countries restrict knife imports (UK, Australia). Sharp blades only in checked bags.
Where to buy authentic matcha?
Uji (Kyoto) is the birthplace. Visit Itohkyuemon Marunouchyasaw or shop. Tokyo Isetanro has a dedicated tea floor.
Why is wagyu expensive?
Raised 28-32 months (vs 18 for US beef), specific feed (corn/soy/wheat/rice straw), daily massage, special genetics, small herd size. Tajima-gyu, Kobe beef, Matsusaka, Yonezawa are top brands.
