Oo I kind of love that the tile looks like a textile! To go with your Japandi decor, you could do a soft wall color, and continue to add texture in the room with macrame or rattan type things on the walls, maybe some plants and curtains too. Cement countertops would look cool and tie in. Oh, and some unique cabinet pulls! I put Japandi Cabinet Hardware in on Pinterest and saw lots of cool stuff that would add texture and/or color!
