99-siki roomazi (99式) is a system of Japanese transliteration developed by the orthographic linguist Tadao Umesao in 1999. Umesao's central principles for 99-siki are to write long vowels as they appear in hiragana (rather than the butchery of passport roomaji, or unsightly and troublesome diacriticals) and to borrow some elements from Hepburn that reflect standard pronunciation. Think of it like Touhou-shiki Roomaji approached from the other side of the Pacific.

Sample of 99-siki from 2ch:

Oomozi wa bunsyou no hazime to koyuumeisi to ni kagirarete imasu.
Watasi wa 99-siki roomazigaki no tumori desu.
