Counting Cups & Drinks: ～杯 (hai)
Grammar Rule in 30 Seconds
Use the counter ～杯 (hai/pai/bai) to count drinks and items served in cups, bowls, or glasses.
- 1. Attach ～杯 directly to the number: 一杯 (ippai).
- 2. Sound changes occur for 1, 3, 6, 8, and 10.
- 3. Use 何杯 (nanbai) to ask 'how many cups?'
Overview
In Japanese, quantifying objects necessitates the use of specific counters (助数詞, _josūshi_), which serve to classify what is being enumerated based on its inherent characteristics. These are not mere numerical suffixes but integral linguistic components that reflect an object's form, nature, or even its perceived function. For learners at the A2 CEFR level, mastering these counters is fundamental for constructing grammatically sound and naturally spoken Japanese sentences.
Among the most frequently encountered is ～杯 (杯, _-hai_), primarily designated for counting servings of liquids or food presented in a receptacle such as a cup, glass, or bowl. This counter implicitly quantifies the contents of such a container.
A defining characteristic of _-hai_—and many other Japanese counters—is its susceptibility to sound changes (音便, _onbin_). The initial /h/ sound frequently mutates to /p/ or /b/ depending on the preceding number, a common phonological process in Japanese aimed at facilitating smoother pronunciation. This phonetic assimilation is a critical aspect of correct usage and a key indicator of fluency.
This counter proves indispensable in daily interactions, ranging from ordering beverages at a café to preparing meals according to a recipe. While its most common application is tied to drinks and bowl-served foods, _-hai_ also possesses a less common, secondary function: counting certain marine creatures like squid and crabs. This seemingly disparate usage stems from a traditional perception of their body shapes resembling cups or pots.
For A2 learners, however, priority should be given to internalizing its application with food and drink. A solid understanding of _-hai_ not only enables practical communication but also deepens your comprehension of the intricate Japanese counting system and its underlying phonetic principles.
How This Grammar Works
数詞 + カウンター + 名詞 (number + counter + noun) or, more commonly, 名詞 + 数詞 + カウンター (noun + number + counter). The counter _-hai_ specifically denotes a serving or a container-full of something, placing emphasis on the volume or the act of consumption from a vessel.コーヒーを一杯お願いします (kōhī o ippai onegaishimasu) for "one coffee, please," rather than 一杯のコーヒーをお願いします (ippai no kōhī o onegaishimasu), though the latter is technically understandable.一 (ichi, one) combined with 杯. The final /chi/ of ichi and the initial /h/ of hai undergo assimilation, resulting in a geminate consonant (the small っ /tsu/ in writing) and a shift from /h/ to /p/, forming 一杯 ({いっぱい}, _ippai_). This transformation is formally known as _sokuonbin_ (促音便) followed by _handakuonbin_ (半濁音便).三 (san, three) and 杯 combine. The nasal consonant /n/ of san triggers a voicing of the /h/ to /b/, creating 三杯 ({さんばい}, _sanbai_). This is an example of _hatsuonbin_ (撥音便) causing _dakuonbin_ (濁音便).Formation Pattern
～杯 (杯) results in systematic, yet often irregular, phonetic changes. These changes, while predictable based on the preceding sound, require memorization for specific numerals, notably 1, 3, 6, 8, 10, and the interrogative "how many." The base form is はい (_hai_), which consistently shifts to ぱい (_pai_) or ばい (_bai_) under specific conditions.
～杯, including pitch accent and the linguistic reasoning for each sound change:
ichi (一) + hai (杯) → The final consonant of ichi (often pronounced /tɕi/ or /çi/) causes gemination (促音便 _sokuonbin_) and half-voicing (半濁音便 _handakuonbin_) of /h/ to /p/. |
ni (二) + hai (杯). No phonetic assimilation occurs. |
san (三) + hai (杯) → The final nasal sound /n/ of san triggers voicing (濁音便 _dakuonbin_) of /h/ to /b/. This is an example of _hatsuonbin_ (撥音便). |
yon (四) + hai (杯). {しはい} (_shihai_) is grammatically correct but less common in modern Japanese. |
go (五) + hai (杯). |
roku (六) + hai (杯) → The final consonant of roku (often pronounced /kɯ/) causes gemination (促音便 _sokuonbin_) and half-voicing (半濁音便 _handakuonbin_) of /h/ to /p/. |
nana (七) + hai (杯). {しちはい} (_shichihai_) is grammatically correct but less common. |
hachi (八) + hai (杯) → The final consonant of hachi (often pronounced /tɕi/) causes gemination (促音便 _sokuonbin_) and half-voicing (半濁音便 _handakuonbin_) of /h/ to /p/. |
kyū (九) + hai (杯). |
jū (十) + hai (杯) → The long vowel /uː/ in jū often shortens and triggers gemination (促音便 _sokuonbin_) and half-voicing (半濁音便 _handakuonbin_) of /h/ to /p/. Also commonly {じっぱい} (_jippai_) and less frequently {とっぱい} (_toppai_). |
nani (何) + hai (杯) → The final nasal sound /n/ of nan (from nani) triggers voicing (濁音便 _dakuonbin_) of /h/ to /b/. This is an example of _hatsuonbin_ (撥音便). |
十一杯 ({じゅういっぱい}, _jūippai_, 11 cups) follows the pattern of 一 (ichi), while 二十三杯 ({にじゅうさんばい}, _nijūsanbai_, 23 cups) follows the pattern of 三 (san). Similarly, 百杯 ({ひゃっぱい}, _hyappai_, 100 cups) follows the pattern of 八 (hachi) or 十 (jū). Consistent, deliberate practice of these combinations aloud is crucial for internalizing the correct pronunciation and achieving natural intonation. Memorizing the rules for the numbers 1, 3, 6, 8, 10, and 'how many' will provide a strong foundation for nearly all other numbers.
When To Use It
～杯 (杯) is specifically employed to quantify items that are served in, or fundamentally constitute a volume within, a cup, glass, bowl, or a similar type of receptacle. Its utility spans across various common scenarios in Japanese daily life, rendering it an indispensable counter for learners to master.～杯. Whether you are referring to hot beverages like coffee or tea, chilled drinks such as juice or water, or alcoholic beverages like beer or sake, if the liquid is served in a cup or glass, ～杯 is the appropriate counter.- When ordering:
すみません、ビールを二杯お願いします。(_Sumimasen, bīru o nihai onegaishimasu._) - "Excuse me, two beers, please." (Polite request at a restaurant or bar). - When describing consumption:
彼は毎晩、お酒を三杯飲みます。(_Kare wa maiban, osake o sanbai nomimasu._) - "He drinks three glasses of alcohol every night." - When offering:
もう一杯いかがですか？(_Mō ippai ikaga desu ka?_) - "Would you like one more (cup)?"
～杯. This category primarily includes soups (e.g., miso soup), noodle dishes like ramen and udon, and donburi (丼) dishes, which are large bowls of rice topped with various ingredients.- Ordering ramen:
ラーメンを一杯食べたいです。(_Rāmen o ippai tabetai desu._) - "I want to eat one bowl of ramen." - Referring to soup:
今日の夕食はスープ二杯でした。(_Kyō no yūshoku wa sūpu nihai deshita._) - "Tonight's dinner was two bowls of soup."
～杯 can be used. While more precise terms like 大さじ (おおさじ, tablespoon) and 小さじ (こさじ, teaspoon) exist, ～杯 can denote a general measure taken with a spoon or a scoop, implying a specific, often standard, quantity.- For a general measure:
砂糖を一杯加えてください。(_Satō o ippai kuwaete kudasai._) - "Please add one spoonful of sugar." (Implies a standard, unspecific spoonful). - With half measures:
塩は半杯で十分です。(_Shio wa hanpai de jūbun desu._) - "Half a spoonful of salt is sufficient." (Note the use of半(はん, half) before the counter).
～杯.- Example in a specialized context:
イカが十杯水揚げされました。(_Ika ga juppai mizuage saremashita._) - "Ten squid were landed (from the sea)."
～杯 is likely the correct counter. The critical consideration is the context of serving, containment, and consumption.Common Mistakes
～杯 (杯), predominantly revolving around its pronunciation, scope of application, and differentiation from other counters. Recognizing and understanding these common errors is the initial step toward achieving accurate usage.いちはい (_ichihai_) instead of いっぱい (_ippai_) or さんはい (_sanhai_) instead of さんばい (_sanbai_) immediately identifies a beginner. While these pronunciations are often understandable, they sound unnatural and disrupt the phonetic rhythm of Japanese. This mistake typically arises from a simplistic application of a "number + counter" rule without accounting for the underlying phonological processes.- Incorrect:
お水をいちはいください。(_Omizu o ichihai kudasai._) - Correct:
お水を一杯ください。(_Omizu o ippai kudasai._) - "One glass of water, please."
～杯 with ～本 (本) for Bottles: A common misapplication is using ～杯 for entire bottles of beverages, particularly alcoholic ones. However, bottles are inherently long, cylindrical objects, and thus correctly quantified with the counter ～本 (本). ～杯 is exclusively for the contents of a container or a serving poured from it, not the sealed container itself. This distinction is crucial for conveying the correct meaning.- Incorrect (if referring to a bottle):
ワインを一杯買いました。(_Wain o ippai kaimashita._) - Correct (for a bottle):
ワインを一本買いました。(_Wain o ippon kaimashita._) - "I bought one bottle of wine." - Correct (for a serving):
ワインを一杯注ぎました。(_Wain o ippai sosogimashita._) - "I poured one glass of wine."
～個 (個) for Drinks or Bowls: The counter ～個 (個) serves as a general-purpose counter for small, discrete, often three-dimensional objects (e.g., apples, erasers, or empty containers). If you intend to refer to an empty glass or bowl as an object, ～個 is appropriate. However, if the container holds something to be consumed, ～杯 is strictly required. Using ～個 for a serving of liquid is a significant grammatical error.- Incorrect (if asking for three servings of juice):
ジュースを三個ください。(_Jūsu o sanko kudasai._) - Correct (for empty glasses):
グラスを三つください。(_Gurasu o mittsu kudasai._) - "Give me three glasses (empty)." (Using the generic～つis also acceptable for empty objects). - Correct (for juice servings):
ジュースを三杯ください。(_Jūsu o sanbai kudasai._) - "Give me three glasses of juice."
～杯 to All Food Items: While ～杯 is correctly used for food served in deep bowls, it is emphatically not used for dishes presented on flat plates. For flat items or meals served on a plate, other counters such as ～枚 (枚) for flat objects (e.g., slices of bread) or ～皿 (皿) for plates of food are appropriate. The key distinction lies in the form of the serving vessel.- Incorrect (if curry is on a flat plate):
カレーライスを一杯注文しました。(_Karēraisu o ippai chūmon shimashita._) - Correct (for a plate of food):
カレーライスを一皿注文しました。(_Karēraisu o hitosara chūmon shimashita._) - "I ordered one plate of curry rice." - Correct (if curry is served in a deep
donburibowl):カレーライスを一杯注文しました。(_Karēraisu o ippai chūmon shimashita._)
～杯 for Non-Liquid/Non-Bowl-Shaped Items: Although the marine animal exception exists, do not extend ～杯 to other items that are not liquid, in bowls, or metaphoricallyCounting Cups (杯)
