Meiji Jingu Shrine
Start in Harajuku with the forest walk into Meiji Jingu, then let the kids run around Yoyogi Park before crossing into Shibuya for the scramble crossing, character shops, snacks, and city lights. It is a much stronger first impression than a quiet temple-only opener, but it still has escape valves: shade, toilets, vending machines, and park space when the city gets too loud. Keep Shinjuku as an after-dinner "only if everyone still has legs" neon stroll, not a required third neighborhood.
