Treading in My Father’s Footsteps


January 30, 2018


Akira Nakajima

President & CEO

NHLab. Inc.


 On December 9th of last year, my father Heitaro Nakajima passed away.

He had started NHLab. Inc. about three years before, on the occasion of retirement of several engineers who once had worked with him for Sony Corporation, intending that the Lab. would be a club-like meeting place for these younger colleagues to continue research and development on audio utilizing their accumulated knowledge and skills. Living together with him,

I had been watching closely he and his colleagues kept on research and development efforts focusing mainly on an egg-shaped loudspeaker for which they had a feeling of expectation for an excellent potential ability.

The egg-shaped loudspeaker was completed in three years, and I hear that dozens have been sold so far. Further, my father said “I want to put a more enhanced and advanced type of loudspeaker system out into the world”.


Now, I would like to inform you that I have decided my mind to be President and CEO of NHLab. Inc. to tread in my father’s footsteps as a same engineer of electric engineering. I have been engaged in examination of commonly known patent examples especially on video equipment including speakers, microphones etc. at the IPCC (Industrial Property Cooperation Center) for about ten years. Though I am not an expert on research and development of audio equipment such as loudspeakers and others, I believe my experience shown in my career summary below will make me be able to contribute to the activities of NHLab. Inc.


NHLab. Inc. is going to enter the fourth year in coming April, and I will aim at strengthening the base of our technology and management with two keywords “seeking for excellent sounds” and “playing with excellent sounds”. I sincerely hope you will give us your continuous cooperation to NHLab. Inc. Thank you very much.
