In a casual conversation with my japanese colleague, they were shocked to know that i drink tap water and asked to reconsider/ drink bottle water as tap water un tokyo can cause bacterial infection, diaheria, and other problem.
I am not going to buy water bottles each day that's stupid but do i need to take more caution ( use those tap water filter being sold on amazon, boil the water and then store it in fridge etc).
Just curious if any of you guys had ro visit a doctor because of tap water.
