Dear ATAGO valued customers and partners,

July, 2020 

Our Bellevue, WA office will be closed on July 3, 2020, but our online shop will remain Open!

April, 2020  

Due to restrictions enforced by our building and  parcel carrier companies, we are only able to accept UPS shipments at this time. Please choose to use UPS  when sending your units to ATAGO USA for repair/calibration services. Undeliverable packagees will be returned to you at your cost. 

Thank you for your cooperation.

March, 2020

As we continue to navigate this troubling situation with the coronavirus, we wanted to take a moment to inform you some of the steps we are taking to ensure the safety of our employees, customers and partners.

At ATAGO, we are limiting the number of people visiting our facility to reduce risks, and all employees are encouraged to take their temperature prior to each work day. All employees are educated with maintaining   proper hygiene practices, advised on how to self-report illnesses and when to seek medical care.

The door handles to the main entryway and common areas in the office are wiped down periodically.

As our proudly made in Japan products arrive to the USA office, just as a precaution, all products are  sanitized  prior to shipping them out to you!




Thank you for choosing ATAGO. We are proud to be your partner and know we will move through this challenging situation together.


Your item will ship either on Tuesday or Friday. For any immediate assistance, please email us at or call us at 425-637-2107 (07:30 to 16:30 PST).


We now accept
