The tickets in Tokyo 2020 Olympic Games will be available soon. Only Japanese and foreign people who are currently living in Japan can join the lottery during the first launching of the tickets. It will be on May 9 to 18, 2019 and the results of the winner will be announced on June 20, 2019. Foreign people who are not residing in Japan cannot buy the tickets in Japanese official ticket website, so they need to buy the tickets in their own countries. All people who wants to participate in the lottery need to register their IDs online via official website. All ticket prices are above 2,500 yen and more than a half of them will be sold less than 8,000 yen. I will participate in the lottery to buy a ticket because it is very rare chance to attend Olympic Games in Japan.
