I attended mass and confession on a weekday evening at St Ignatius in Tokyo and took two blurry photos. The sacrament of reconciliation is available between 5-7pm Mon-Fri in the main church. There was a line when I was there so in all it took about one hour, after which I stayed for the 6pm mass in Japanese. The mass is only 30 minutes long.
I found it very similar to Kobe Chuo church I visited before in several ways. It has the same round shape, the same stations of the cross hidden in offset stained glass windows, and the same flying Jesus on the wall instead of Christ crucified on a cross. On the other hand the confession was good. Also you will notice in one photo a woman has her head covered something I had never witnessed until I came to Japan. The church holds 800 and for a weekday evening I was surprised there were quite a few people there. The photos were taken after mass had ended and people had started to leave.
