Hapi-Line Fukui is a newly established third-sector railway line launched in conjunction with the extension of the Hokuriku Shinkansen from Kanazawa to Tsuruga in March 2024. With this opening, the section from Daishoji to Tsuruga was separated from JR's management. Sixteen 2-car 521 series trains, which had been operating on the same line, have been transferred, featuring an original pink-based color scheme. Furthermore, in June of the same year, a full-wrap version appeared, attracting attention with its vibrant appearance.
- The two-car set is based on the HF11 train, and the four-car set represents the HF09 and HF10 trains.
- Vivid pink color scheme faithfully reproduced. The special edition product combines the standard color and full wrap formations in a four-car set.
- Front dummy couplers equipped. By exchanging with the included front coupling coupler, coupling between front cars is possible.
- Intermediate coupler features a body-mount tight-coupler (without hook).
- Equipped with a slotless motor, ensuring smoother and quieter operation. For replacement, the two-car set includes "Rapid Tsuruga" and plain, while the four-car set includes "Local Fukui" and plain.
