There is probably only one person in Japan who is so strictly salt-free and sugar-free.

This article describes how to create reel-to-reel video ads and how to distribute ads.

Procedure and Points to Note when Doing the Procedures for Increasing Capital by Yourself

The other day, after a long time, I prepared the documents for the capital increase procedure by myself and submitted them to the Legal Department, and as expected? I found a flaw and the Legal Affairs Bureau called me and asked me to correct it (they were very polite), so I am writing this down as a reminder. The paperwork is not that difficult and a simple capital increase can be done in 30 minutes, so it is better to do it quickly by yourself and even if there are corrections, just follow the instructions of the person in charge.
