Sayonara Umihara Kawase

Umihara Kawase is a series of platform games, starring a nineteen-year-old Japanese school girl (Kawase Umihara), who has somehow become lost in a world of mutated salt-water and fresh-water creatures.

The Umihara Kawase games' main distinction are their tranquil fish and bird infested worlds and the rope physics, which defines the gameplay.

The Nintendo 3DS (2011) added glasses-free stereoscopic 3D and a second analog input to Nintendo's handheld line, eventually building a library that rivaled the DS in size and quality. Because the eShop for digital purchases has since closed, physical 3DS cartridges are the only way to preserve access to many titles — a dynamic that's pushing more collectors toward cartridge-based copies even for games that were originally digital-first.

Gamevaro tracks Sayonara Umihara Kawase for Nintendo 3DS with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Sayonara Umihara Kawase to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This 3DS release dates back to 2013.

Market insights

Sayonara Umihara Kawase has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
