digraph D {
   b1 [label = "第一次川中島の戦い\n1553年"];
   b2 [label = "第二次川中島の戦い\n1555年"];
   b4 [label = "第三次川中島の戦い\n1557年"];
   b1 -> b2 -> b4;
}

Thanks for your report @kaala 👍
I can reproduce this issue, I will investigate!

@kaala Apparently, it was fixed in bd124e0

Could you please confirm that Japanese texts now render properly? Not sure if wqy-zenhei is good enough or if we should use Noto CJK instead?

Thank you, render result looks good.
