Python user.

Sorry but I will provide these libraries only to direct acquaintance because they are not so sophisticated.
However if you are interested, please contact me in person or via twitter.
I may share more information about the library.
Especially if you are a student of seismology in Japan, I am happy to support your research by sharing my labrary.

公開レベルでないため知人にのみ提供のつもりですが，
もしも詳細に興味があれば対面かTwitterでご相談ください。
特に学生の方の場合は，できる限り積極的にライブラリを共有しようと思います。
いずれもpipでインストールできる状態のファイルです。

  A library to read/write WIN format data, channel table and files related to hypomh (velocity structure, seis file, etc.).

• seisdbpy
  
  Download and parse data from seismic database by Japanese organizations.

• beachballpy
