What it is
The company traces its chef-knife business to 1866 (Keio 2), when founder Minosuke Matsuzawa began making culinary knives in Osawa (now Saitama); the company dates its first Kanto Honyaki culinary-knife manufacture and sales to 1874, and the Azumabashi shop to 1890. Masamoto Sohonten Co., Ltd. (株式会社正本総本店) is one of Japan's most revered knife houses among master sushi and kaiseki chefs worldwide. Operating its headquarters showroom in Azumabashi, Sumida-ku (just across the Sumida River from Asakusa and minutes from Tokyo Skytree), Masamoto Sohonten is distinguished from similarly named shops (such as Tsukiji Masamoto, which is a separate company).
Professional chefs travel from across the globe to Azumabashi to acquire Masamoto Sohonten's signature Honkasumi Gyokuhakuko (white steel) Yanagiba sashimi knives, mirror-polished Honyaki master blades, and its Sumida Modern-certified Hyper Molybdenum stainless Western knives. Importantly, the Azumabashi headquarters operates strictly on weekdays (9:00 AM–5:00 PM) and is completely closed on Saturdays, Sundays, and Japanese holidays.
How to order
Step 1: Planning Your Visit Strictly on a Weekday
- Azumabashi Main Store Address: 1-6-5 Azumabashi, Sumida-ku, Tokyo (2 minutes on foot from Honjo-Azumabashi Station on the Toei Asakusa Line, or 6 minutes from Asakusa Station).
- CRITICAL SCHEDULE RULE: The Main Store operates Monday through Friday from 9:00 AM to 5:00 PM, and is COMPLETELY CLOSED on Saturdays, Sundays, and Japanese national holidays.
- Weekend shopping alert: Do not travel to the former Sumida Machidokoro counter in Tokyo Solamachi 5F as an alternative: the facility closed on March 31, 2022. The official Azumabashi store is closed on weekends and national holidays; contact the company about current authorized sellers rather than assuming a substitute.
Step 2: Consulting Staff on Professional Blade Grades
- Browse the glass display cabinets showing blade lengths (in millimeters, e.g., 210mm, 240mm, 270mm, 300mm) and handle styles (traditional Magnolia Ho-wood with buffalo horn ferrule vs. Western full-tang).
- Choosing Steel:
- Hyper Molybdenum Steel: Sumida Modern-certified high-carbon stainless steel—balanced, hygienic, and rust-resistant for Western-style Gyuto and Petty knives.
- Honkasumi Gyokuhakuko (white steel): Traditional laminated carbon steel delivering extraordinary razor sharpness for sushi and vegetable prep (requires strict drying after every use).
- Honyaki: Single-steel differential clay-tempered master blades forged for experienced professionals.
Step 3: Mandatory Flight Packing Rules (Checked Luggage Only!)
- CRITICAL AVIATION LAW: All Masamoto Sohonten knives are strictly prohibited in aircraft cabin carry-on baggage. Pack every boxed knife securely inside your checked suitcase.
Step 4: Checkout & 2026 Tax-Refund Procedure
- Confirm the store's tax-free status first. The company website records that Masamoto Sohonten began tax-free sales in 2015, but ask the Azumabashi store to confirm its current November 2026 refund-method procedures and method of repayment.
- At purchase: Eligible nonresident customers buying qualifying goods worth at least ¥5,000 (excluding tax) at one participating store on one day pay the full tax-inclusive price. Show the identity/residency documents requested by the store and arrange its refund procedure. The retailer sends the purchase information electronically; a passport-chip scan by a cashier is not a universal legal requirement.
- At departure: Within 90 days of purchase, complete Customs' export verification at the designated airport or seaport terminal before handing over checked baggage. A green result completes the procedure without goods inspection; a red result requires taking the goods to Customs for physical verification. Keep your purchased items accessible until the process is complete.
- For knives: Use checked baggage, not cabin luggage. Check your airline's packing rules and import restrictions in the destination country.
- Refund: After Customs confirms export, the seller or its designated provider uses the payment/refund arrangement explained when you bought the goods. Available methods vary and may include bank, card, app or a participating airport cash service; cash is not paid out by Japan Customs as a universal service.

Payment & practical info

- Tax-refund shopping after November 1, 2026: Ask whether this specific outlet participates. If it does, qualifying purchases of at least ¥5,000 excluding tax per shop/day are paid at tax-inclusive prices. Complete Japan Customs export verification within 90 days of purchase and before checked-bag drop; show goods only if inspection is requested. The merchant/refund operator explains the refund method, which is not uniformly restricted to credit cards.

Good to know / Common mistakes
1. Weekday-Only Schedule (Closed Weekends & Holidays!)
Many travelers walk across the bridge from Asakusa on a Saturday afternoon only to find Masamoto Sohonten closed. Schedule your Azumabashi visit strictly on a Monday–Friday weekday between 9:00 AM and 5:00 PM!
2. Do Not Confuse Masamoto Sohonten with Tsukiji Masamoto
Masamoto Sohonten (吾妻橋 / Azumabashi) and Tsukiji Masamoto are separate legal entities with separate management and product lines.
3. Discounts and Promotions
- Discounts and promotions: Check current official store notices for any applicable offer; do not assume a regular coupon program.
FAQ
Q1: Can left-handed chefs buy left-handed single-bevel knives at Masamoto Sohonten?
Masamoto Sohonten produces both right-handed and left-handed (Hidari-kiki) single-bevel Japanese knives, though left-handed stock is specialized and may carry higher pricing or require ordering—ask counter staff or inquire via their English site in advance.
Q2: Can I bring a Masamoto knife in my carry-on bag if it is wrapped in a wooden Saya?
No. Airport security strictly confiscates all kitchen knives from cabin carry-on luggage regardless of protective sheaths or gift boxes. Always pack knives in your checked suitcase.
Q3: How do I receive my consumption tax refund under the 2026 airport customs system?
First confirm that the exact store offers the post-November 1, 2026 tax-refund procedure and register your refund details there when purchasing. Pay the tax-inclusive price. Within 90 days of purchase, complete Customs' export verification at your departure airport or seaport before checking your luggage. The terminal will tell you if Customs needs to examine your goods; keep them accessible until verification is finished. After confirmation, receive any eligible refund by the method arranged by the seller or its provider. The process and availability of airport cash refunds vary by provider.
