My son joined the school tennis club. My wife and he bought his tennis shoes for 3999 yen ($39.21 €28.36) at SportsDepo. There are two types of tennis shoes in Japan. One is "for all types of courts", the other is "for OmniCourt". OmniCourt is a kind of artificial turf tennis court developped by Sumitomo Rubber Industries. This type of courts are in widespread use all over the country. The teacher instructed my son to buy shoes for all types of courts, because the school court is just a dirt ground.
