December 2012 We have decided to take over the antenna-related business of Mizuho Tsushin, which ended its business activities on the occasion of its 40th anniversary.
Mizuho Communication + Micro Power Research Institute's new brand Mizuho Communication Research Institute has been born.
Accordingly, some of the products sold by bar-antenna.com will be transferred to Mizuho Communication Research Institute.
From now on, prototypes and custom-made products will be sent to bar-antenna.com, and completed products will be sent to Mizuho Communication Research Institute.

The URL of Mizuho Communication Laboratory is http://mizuho-lab.com .
Please note that bar-antenna.com and Mizuho Communication Research Institute are both operated by Micro Power Research Institute, so
Micro Power Research Institute will be the point of contact for all orders.

From 2018, the URL of the nationwide radio hotspot expedition has changed.
