方法 and 手口 both translate as “method” or “way” in English — but one is neutral and the other is almost always used for criminal or deceptive methods!


方法 (houhou) is a neutral word for method or way of doing something. 手口 (teguchi) specifically means a criminal’s method or the way a trick or crime is carried out — it has a very negative, shady nuance.
| 方法 (houhou) | 手口 (teguchi) | |
|---|---|---|
| Meaning | Method / way / means | Criminal method / trick / modus operandi |
| Nuance | Neutral — any method | Negative — criminal, deceptive, or cunning method |
| Used for | Any situation | Crime, scams, tricks, frauds |
| Example | 勉強方法を教えて。 | 犯人の手口が明らかになった。 |
方法 — Neutral Method
方法 (houhou) is the standard, neutral word for “method,” “way,” or “means.” It can be used for any type of process or approach — positive, negative, or neutral.
- 効果的な勉強方法を教えてください。— Please teach me an effective study method.
- 解決方法が見つかった。— A solution (method) was found.
- 別の方法を試してみよう。— Let’s try a different method.
- 支払い方法を選んでください。— Please select a payment method.
手口 — Criminal or Deceptive Method
手口 (teguchi) literally means “hand mouth” — the tricks of the trade used by criminals or swindlers. It carries a clear negative nuance of cunning, deception, or criminal methodology.
- 犯人の手口が明らかになった。— The criminal’s method was revealed.
- 詐欺の手口に気をつけて。— Watch out for scam tactics.
- 古典的な手口だ。— It’s a classic trick / old scheme.
- 新しい手口の振り込め詐欺が増えている。— New-method phone scams are increasing.
Common Mistakes for English Speakers
English “method” is neutral, but 手口 is never neutral — it always implies something shady or criminal. Don’t use 手口 to describe cooking techniques or study methods. If you accidentally use 手口 in a neutral context, it will sound like you are describing a criminal scheme.
