Nova Nail Namba at Dotonbori, Osaka

Korean-style nail salon near JR Namba with 500-plus colours, length extensions and late-night booking.

Nova Nail Namba is a nail salon in the Namba Mitsumi Co-op building in Moto-machi, Naniha Ward, a one-minute walk from JR Namba Station and three minutes from the subway's Namba and Yotsubashi stations. The salon specialises in Korean and one-hon style nails, with a particular strength in length extensions using tips, alongside gel one-colour, French, magnet and gradation designs. With more than 500 colours and over 1,000 decorative parts to choose from, the menu leans towards the sparkly, glossy and trend-led, covering everything from "churu" soft-gloss looks to Y2K and more niche subculture styles. Practical options make it popular with both locals and tourists: late-night reservations are accepted, student-discount menus are available, and gel one-colour treatments start from around 4,500 yen. Designs brought in by clients can usually be accommodated, which appeals to customers arriving with a specific reference image. Because of building regulations, visitors are asked to call or message ahead for the entry password before arriving, a small but important detail to note when booking. The salon is highly rated on booking platforms, with strong repeat-customer numbers and high satisfaction scores for both finish and service. For anyone wanting detailed, Korean-influenced nail art in a convenient central-Namba location, Nova Nail is a polished, well-reviewed option. It is the kind of salon where the part selection alone is worth browsing before your appointment.
