Quick answer: yes, there’s a real superstition in Japan around giving knives as gifts — but it’s now widely reframed as a positive one, and there’s a simple, well-established way to give one anyway. Details below, plus two genuinely gift-worthy Japanese knives if you’ve decided to go ahead.
Some of the shops we link to are partners who may pay us when you buy through them. This doesn't change which pieces we recommend. How this works.
Where the Superstition Comes From
In Japan, a knife — like scissors or any other cutting tool — is traditionally considered an unlucky gift because it symbolically “cuts” (kiru) a relationship. Sakai Ichimonji Mitsuhide, a long-established knife maker in Sakai, explains this directly on its own gifting guide: giving something that cuts has historically been read as an omen for cutting ties with the recipient, which is why knives were traditionally kept off gift lists for weddings, housewarmings, and similar occasions.
That said, the same source — and Sakai Jikko, another established Sakai cutlery shop — both describe a widespread modern reinterpretation: instead of “cutting ties,” a knife can represent “cutting open” (kirihiraku) a path to the future. That reframing is why knives have become a genuinely popular gift for opening a business, moving into a new home, or getting married — occasions about starting something, not ending it.

The 5-Yen Coin Workaround
If you want to sidestep the superstition entirely rather than lean on the positive reframing, there’s a specific, well-documented custom for it: the giver includes a small coin — traditionally a 5-yen coin — with the knife, and the recipient hands that coin back as a token “payment.” Because the recipient technically bought the knife rather than received it as a gift, the “cutting ties” symbolism doesn’t apply. Heart Knife’s guide to the custom goes into more detail on the specific etiquette.
It’s a small gesture — you’re not actually charging the recipient 5 yen for a knife — but it’s the traditional way to give a blade with a clean conscience, and it’s a nice detail to mention if you’re giving one to someone who’d appreciate knowing the custom.
Knives and Yakudoshi (Unlucky Years)
There’s a related but distinct tradition worth knowing: giving a knife to someone in their yakudoshi (an unlucky year in a traditional age-based calendar) as a protective gift. Sakai Jikko’s explainer notes that blades have long been believed to “cut off calamity and open good fortune,” and were historically used as offerings in Shinto rituals as a symbol of authority — which is the basis for giving one specifically as a yakudoshi charm rather than a general-purpose gift.

If You’re Giving One Anyway
Whether you lean on the “cutting open a new path” reframing or the coin custom, a knife with some story or credibility behind it makes a better gift than an anonymous one. Two we can actually vouch for:
- The Sori Yanagi Kitchen Knife — designed by a celebrated Japanese industrial designer, with real design-collection credentials rather than just marketing. We cover it in full in our santoku knife roundup.
- The Shun Classic Santoku, manufactured by Kai Corporation in Seki, Gifu — see our full writeup in our guide to verified Made-in-Japan knife brands.

If you’re sourcing a knife from somewhere other than the two picks above, it’s worth checking the listing against our guide to spotting fake Japanese knives first — giving a knife that turns out to be a Chinese-made import wearing a Japanese name undercuts the whole gesture.
Don’t forget the 5-yen coin if the recipient would appreciate the gesture.
If a knife feels like too much of a wildcard for the occasion, our guide to Japanese housewarming gifts covers the safer picks — plus the fire- and red-color taboos that also apply to new-home gifts.
FAQ
Is it actually bad luck, or just an old superstition? It’s a cultural superstition, not a belief most people in Japan treat as literal — but it’s real enough that knife retailers in Japan build gifting guidance around it, and many people still observe the coin custom out of courtesy or tradition rather than genuine fear of bad luck.
Does the superstition apply to any bladed item, or just kitchen knives? Traditionally it extends to scissors and other cutting tools as well, for the same “cutting ties” symbolism — kitchen knives are just the most commonly gifted example.
Do I need to use a 5-yen coin specifically, or does any coin work? The 5-yen coin is traditional partly because its Japanese name (go-en) is a homophone for “good fortune” or “connection,” which layers a second good-luck meaning on top of the “token payment” workaround. Any small coin technically completes the custom, but a 5-yen coin is the version with the added wordplay.

Final Thoughts
A knife is one of the few gifts in Japanese gift-giving etiquette that comes with its own built-in superstition — and its own built-in workaround. Lean on the “cutting open a new path” framing for house-warmings, weddings, or new ventures, add a 5-yen coin if you want to cover all your bases, and pick a knife with some actual story behind it.
