Amakusa Sonar Beer announced on Instagram, "New Release from March 19 at 3:00 p.m.". The post explains the sales start times as follows.

- Sales start for wholesale customers: March 19 at 3:00 p.m.
- General sales start: March 19 at 5:00 p.m.

The same post includes hashtags such as `#sonardrop`, `#westcoastpilsner`, and `#wcp`, suggesting that this new release is a West Coast Pilsner style. Since the post does not clearly state the detailed specs, price, or format of the beer (such as cans or kegs), more information is expected in a follow-up update.

Amakusa Sonar Beer is a brewery based in Amakusa, Kumamoto. On its official website, it says it makes beer using hops grown in Japan's westernmost hop field and mineral-rich groundwater. Known for characterful beers centered on locally sourced ingredients, this new release is likely to attract plenty of attention as well.

Because this announcement points to activity on the release day, anyone interested should check the sales start time carefully.
