In a small dish, whisk together the turmeric, shichimi togarashi, rice vinegar, sesame oil, honey, and salt until emulsified and set aside.
Pat the shrimp dry, and skewer with the pineapple, white and light green scallions, and jalapeño. Use a pastry brush to distribute the glaze between the skewers and season with salt.
Preheat a covered grill to high heat. Grill the skewers for 5 minutes uncovered, then flip, cover, and cook 3 minutes more, or until shrimp is opaque throughout.
Serve the skewers topped with the thinly sliced scallion greens and cilantro, alongside the brown rice and lime wedges.
