The company has not explicitly identified the concept as the new 2, but, described today as a "next-generation subcompact car", there can be little doubt.
The site of the concept's unveiling also carries a clue, with the Geneva show playing host to the current Mazda2's global premiere back in 2007.
That makes the Hazumi's coming rather timely, with the second-generation Mazda2 now marching into its seventh year on the market - and it will likely be 2015 before this new model hits showrooms.
Mazda is not struggling for success in the light-car segment however, with the current 2 still leading the pack in Australia.
The shadowy teaser released today suggests the Hazumi will debut with near production-ready styling, although we can likely expect the compact headlight design to grow larger - as its siblings did in the leap from concept to production.
Last month, 'Photochop' wizard Theophilus Chin offered TMR readers a look at what might come with the new 2, and it appears his 'guesstimate' was not far off.
Little has been revealed about the new Mazda2, although reports in the past year have claimed that the light hatch will ride on a shortened version of the larger Mazda3 and CX-5 platform.
We should also see Mazda's new 'Skyactiv 2' engines in the new hatch, outlined in an interview with Mazda's powertrain boss Mitsuo Hitomi.
Watch for the Hazumi to debut next month.
