Information on the Japanese Cutter, Aso (PL-41), referenced in the PACAREA news release below is available here. Aso is larger than a 210 but smaller than a 270, probably about 1,200 tons full load. She is propelled by four diesels and four water jets and capable of over 30 knots. She is armed with a 40mm/70 and has a crew of 30. Reportedly Japan is building six similar but slightly larger vessels for the Vietnamese Coast Guard.

YOKOSUKA, Japan — U.S. Coast Guard members aboard the Alameda-based Coast Guard Cutter Munro (WMSL 755) participated in a cooperative two-day deployment with Japan Coast Guard members aboard the Japan Coast Guard ship Aso in the East China Sea Tuesday and Wednesday.
The engagement followed Munro’s port visit in Sasebo, Japan, Aug. 20-24, and included crew exchanges; two-ship communication, formation, maneuvering and navigation exercises; joint and cooperative maritime presence; maritime law enforcement training and exercises; and several variations of large ship and small boat operations.
“These at-sea engagements with one of our longest-standing partners in the Indo-Pacific region provided excellent opportunities for our crews to train together and learn from each other, further strengthening our alliances and maritime partnerships,” said Munro‘s Commanding Officer Capt. Blake Novak. “Conducting operations and exercises leverages our strong and trusted relationships while expanding our regional security cooperation initiatives and bolstering collaboration in the Indo-Pacific.”
The U.S. and Japan Coast Guards have a long history of cooperation and several recent engagements. In June 2021, the sea services conducted search and rescue training together in Honolulu before teaming up to search for a missing free diver off Kauai, Hawaii. Earlier this year, the U.S. Coast Guard Cutter Kimball and Japan Coast Guard Ship Akitsushima conducted drills together near the Ogasawara Islands of Japan alongside helicopters and unmanned aerial vehicles to practice interdicting simulated foreign vessels operating illegally inside Japanese waters.
“Partnering with like-minded maritime forces to cross train and expand multi-nation expertise in search and rescue, maritime environmental protection and maritime law enforcement allows our nations to promote regional stability, confront malign activities and threats, and uphold the international rules-based-order underpinning our shared security and prosperity,” said Vice Adm. Michael F. McAllister, commander U.S. Coast Guard Pacific Area.
Munro, a 418-foot national security cutter, departed its homeport of Alameda for a months-long deployment to the Western Pacific. Operating under the tactical control of U.S. 7th Fleet, the cutter and crew are engaging in cooperative maritime activities, professional exchanges, and capacity-building exercises with partner nations and will patrol and conduct operations as directed.
As both a federal law enforcement agency and an armed force, the U.S. Coast Guard routinely deploys worldwide its cutters, boats, aircraft and deployable specialized forces.
The Naval Service does not compete, deter, or fight alone. The Navy, Marine Corps and Coast Guard team are an integral part of the Joint Force and work closely with allies, partners, and other government agencies.
