3M Ultrathon Insect Repellent Lotion

Use this - it is the best. I have used it for almost 10 years while I have seen other tourists get eaten alive and I got no bites - Japan, Korea, China, Thailand, Cambodia. Vietnam, Myanmar, India, Nepal. I also soak my clothes in permethrin before I go on a trip. And I use malerone if it's a malaria area. Remember there are mosquito borne illnesses that have no prevention nor cure. Your only defense is not to get bit. And wear socks and long pants. Long sleeves are also good but I don't like them.
