Notices to Mariners

Notices of small corrections are also included, as these are needed to update (correct) the information on nautical charts.
Notices of small corrections are also included, as these are needed to update (correct) the information on nautical charts.

In addition to Japanese Notices to Mariners, we provide Notices to Mariners from other countries, from the latest issues to back numbers.
We also handle tracings for correcting nautical charts (the Japanese ones are issued by the Japan Hydrographic Association), which are prepared based on Notices for Small Corrections. Tracings are really convenient, as they make the work of correcting charts onboard ship or in the office more accurate and efficient. We deal in US and UK tracings in addition to Japanese tracings. (Prices vary by country. Additional postage is charged for orders of single items.)

We offer a service that provides regular delivery of various country’s Notices to Mariners direct to your office. The contact is for one year, and renewal is required each year to continue the service.

Check the Japan Coast Guard’s Notices to Mariners website for details and the full versions of Japanese Notices to Mariners.

The above site provides PDF editions of each notice. You can obtain the full versions of notices and search for small corrections by chart number.
