From the lessons learned in the 1991 dispatch of the Japanese Self-Defense Forces to the Persian Gulf, the JMSDF took the example of the Royal Navy's Sandown-class minehunter, built after the 1994 plan especially in order to improve its capabilities regarding mine clearance. However, due to the fact that Sandown-class was basically a minesweeper that did not have minesweeping ability and the fact that the waters around Japan have many muddy seabeds that are not suitable for minesweeping, the abandonment of minesweeping ability was unacceptable to the JMSDF. For these reasons, the ships have the ability to sweep with Australian-made DYAD-sensitive minesweepers, but, due to magnetic management issues, it was decided that it would not be installed all the time but would be received from a mother shipat sea as needed. Operational restrictions were large, and mobility was also restricted.
