1 year old has a fever. Any pediatric clinics near namba

Day 3 in japan and our son suddenly got a fever yesterday (Sept 24 around 4-5pm). We gave him paracetamol around 7pm and at 1:35am. We woke up 4:30am and his temp is 38.2. It's a little too high 3 hrs after taking his meds. We are unsure why he randomly got sick he doesn't get sick often. Could it be from the mmrv vaccine (given sept 11) or what….

We are currently staying at namba area, can you guys suggest a great hospital/clinic that has a pedia that is near us?
