How to write "I am (name)" using hiragana?


In a book I've learned "(name) to moushimasu" as an introduction, but as
japanese has no spaces, would it be written with hiragana as follows or
something different?

(name)ともうします。




If your name Zach is written in Japanese as ザック or ザッハ, you would introduce
yourself as (1).

> (1) ザックともうします。 or ザッハともうします。

Your guess is perfectly correct.  
As you know we don't use a space between words, so it is also difficult even
for native speakers of Japanese how to parse (1) at first glance.  
"と", "も" and "とも" are all possible particles and "もう" could be an adverb in
Japanese language. In a short time, you have to understand that "と" is a
particle but "も", "とも" and "もう" do not function as they are, but they are part
of another word.

To solve this kind of difficulty, we use _kanji_ if possible. You can rewrite
(1) into (2) with using kanji.

> (2) ザックと申{もう}します。 or ザッハと申｛もう｝します。

Now you can understand the meaning of (2) at first glance because you can
easily parse the sentence without getting confused by spurious elements such
as "も", "とも" and "もう" in (1).
