Hyaku 100
In the romaji (using Latin letters to spell out the pronunciation) spelling they are as follows a pattern is clearly evident so I will show 1-30 then the multiples of ten until 100(words in parentheses are other ways to say them):

1 - ichi (Sho is also another for of the number 1; however "sho is not used to count is it used to give something a number like saying first =Shodan {corrected by Chip also self taught})

2 - ni

3 - san

4 - yon (or "shi" which is also the word used for death or other morbid things which is why it is not commonly used for the number meaning) (Shi = 4 while yon = 4th you use shi when you say how many of something and yon when you give that something a number like saying it's the fourth apple you would say that the apple is "yondan" {corrected by Chip also self taught})

5 - go

6 - roku

7 - nana (shichi)

8 - hachi

*I forgot to put this in last night when I answered this(was not a member when i answered it but now I am), "chi" can also take the place of one of either "sen" or "hyaku". I'm not adding this into the actual list though, because I can't remember where and its not used to count, or at least not to my knowledge. Also this list is subject to change from anyone who thinks otherwise of my answer since I had to teach myself, however I'm almost 100% certain on these being the numbers to one million. I hope this has answered your query though.{revised by Kittysannihongo} Just so you know the number "juu" is with two "u"s so that the hiragana is really three characters long.
