चिनी पद्धती प्रमाणे, जपानी पद्धतीत संख्या लिहिताना 10000 (दहा हजार) चे समूहा करून लिहीतात. हे पाश्चिमात्य पद्धती पासुन थोडे वेगळे आहे, ज्यात हजारचे (1000) समुह बनवले जातात. (अधिक माहिती साठी पहा मायरियाड):
Variation is due to Jinkōki, Japan's oldest mathematics text. The initial edition was published in 1627. It had many errors. Most of these were fixed in the 1631 edition. In 1634 there was yet another edition which again changed a few values. The above variation is due to inconsistencies in the latter two editions.

However, numbers written in Arabic numerals are separated by commas every three digits following Western convention. If Arabic numbers and kanji are used in combination, Western orders of magnitude may be used for numbers smaller than 10,000 (e.g. 2,500万 for 25,000,000).

In Japanese, when long numbers are written out in kanji, zeros are omitted for all powers of ten. Hence 4002 is 四千二 (In contrast, Chinese requires the use of 零 wherever a zero appears, e.g. 四千零二 for 4002). However, in reading, the letter zero is sometimes pronounced as "tobi" (飛び) or "tonde" (飛んで) to indicate the lack of numbers, e.g. "yon-sen tobi ni" or "yon-sen tonde ni" can be used instead of the normal "yon-sen ni".
