In texStudio basically the following code returns the expected result:
\documentclass{article}\usepackage{mathtools}\usepackage[japanese]{babel}\begin{document} \[ \begin{rcases} \begin{rcases} \begin{alignedat}{2} V \\[-1.5ex] \\[-1.25ex] I -adj \end{alignedat} \end{rcases} % Jisho \\ \text{Jisho}\\ \begin{rcases} \begin{alignedat}{2} NA -adj \\[-1.5ex] \\[-1.25ex] N1 \end{alignedat} \end{rcases} \begin{split} Jisho\\Trans \end{split} \end{rcases} \text{Result} \]\end{document} As you can see, the two braces left are not aligned.Is it possible to align on the brace-symbol?
