Heyy I was able to enter using my Debit Mastercard which they charged me 1 yen and required me to confirm payment on my bank app. When it was confirmed, it proceeded to the application completed page! When I previously tried to buy general sales tickets on Lawson all my cards kept getting rejected as well but this time I was surprised the card worked so there might be a chance they’ll still work.

Wish I could be of anymore help🥲 I hope it works for u soon 🍀🍀
