Scientists are finding new unknown bacteria in the bellybutton, including a bacterium previously found only on Japanese soil.

The claim that scientists are finding new unknown bacteria in bellybuttons is supported by multiple sources, highlighting the significant diversity found in the human bellybutton microbiome. However, the specific claim that a bacterium previously found only on Japanese soil was discovered in a person's bellybutton lacks direct evidence. The available sources discussed different Japanese bacterium discoveries unrelated to bellybuttons, such as plastic-eating bacteria identified by Japanese scientists. Therefore, while the notion of unique bellybutton bacteria is supported, the specific claim about a Japanese soil bacterium found in a bellybutton remains unverified.
