The address number "444" appears to be a fictional creation, likely intended to avoid search indexing. The repetition of the number "4"—which is pronounced shi (死), meaning "death" in Japanese—has been interpreted symbolically by fans.

In Japan's real address system, three-digit block numbers are rare in urban areas; numbers in the 300–400 range are more commonly found in rural regions. This suggests that the address was deliberately crafted with symbolic weight rather than geographic realism.

And, In the original work, on December 21st, 2009—the winter solstice in Japan—Mikami is seen using the Death Note on a train, where he’s eventually caught by Gevanni.

Notably, the light outside the train window suggests it's already dark, which aligns with the short daylight hours typical of the solstice.

From this, we can infer that Mikami commutes by above-ground train and finishes work in the early evening, likely after sunset during the winter season.
