Why Japanese in Japan are not good at talking politics in public

After I came to the US, I saw many people involved in politics. In Japan, debating politics is kinda taboo. I’ve been wondering why. I think I found a potential great reason. Discussing politics and doing political activities in public schools and public facilities is strictly prohibited in Japan. The Iwakura City has a public conference room services which I use it for CoderDojo Owari, The place prohibit to do any political and religious activities by its terms of services. I think this may be coming from World War II how Japanese imperial government brainwashed Japanese citizen to go towards war using education, politics and religion. Therefore, the government should […]

Attending DojoCon Japan 2017

I love open source and community around it. My job is to spread the open source spirits and business in Japan. Now I am the father of two lovely daughters. It’s no brainer that I started CoderDojo Owari in my town since April 2017 and help DojoCon Japan 2017. I was fortunate to be a translator for the event. As a translator, let me briefly introduce what was going on at DojoCon Japan 2017. (I also want to emphasize that Japan now has more than 100 Dojos! We are one of the most active CoderDojo communities in the world!) (Photos by Atsushi Ando & Michie Yamamoto) This is a blog entry […]


How to run concrete5 behind CloudFlare and AWS ELB

This is valid after concrete5.7. Since implementing Symfony framework, concrete5 is equipped with IP check. If the user changed the originated IP address, concrete5 will log you out. However, this security measurement doesn’t go well with advanced load balancer such as AWS Elastic Load Balancer or CloudFlare. From concrete5’s POV, it can only see the IP addresses of the load balancer ($_SERVER[‘REMOTE_ADDR’] to be exact). Because the balancer’s IP address will constantly be changing, concrete5 (Symfony framework) think your ID&PW may be stolen and log you out. First, you must make sure that the security group of EC2 server is only allowing the incoming access from ELB. You will get the […]


The Era of Glocalization

Happy new year of 2017. I will write a kind of new year’s resolution. In these days, I am often being asked what I can do, what I can do to help others, what I really want to do. I think one of my most advantage is the ability to glocalize. In 2017, I would like to appeal my glocal experience to both multilingual projects and inter-industry projects. Dictionaty.com has the definition of glocal. global (adjective) of or relating to the interconnection of global and local issues, factors,etc.: e.g.: a glocal conference on community development. of or relating to the tailoring of globally available products and services to local markets: e.g.: a […]

The year of 2016 was awesome for Mautic Community in Japan. 5 meetup groups have launched in Japan. All of them are actively organizing meetups to spread the word of Mautic.

Japanese mentality is similar to hidden Trump supporters?

I had an occasion to witness the similarity to Japanese mentality and hidden Trump supporters mentality. Japanese who don’t speak out When Japanese people are having some business and political relationship problem, they don’t really speak out they’re having problem. It’s very rare that they speak out. When they speak out to the public, it’s usually too late. (The problem usually becomes big problem). If you’re a leader in Japan, you need to be able to catch the problem and solve it before it becomes ‘public‘. If you cannot catch the problem before it becomes public, the leaders are responsible. Japanese have a custom to respect others. Usually, Japanese don’t want to look […]

Sakura Internet, Japan’s major hosting, recognizes concrete5 by offering auto-installer before Drupal and Joomla

On Feb 2, 2016, Japan’s hosting giant, Sakura Internet started offering quick install of concrete5 CMS. Sakura Internet may be like the combination of Dreamhost and MediaTemple. They are the pioneer to introduce inexpensive shared hosting, affordable VPS, cloud, and IoT hosting to the Japanese market. Although Sakura Internet provides innovative services, the shared hosting department is very conservative because they don’t want to confuse its large number of customers. Previously, they only offered WordPress quick install for content CMS. But, they started offering quick install of concrete5. Therefore, I could say that one of Japan’s best and innovative internet hosting service chose concrete5 before Drupal or Joomla. concrete5 Japan users group has been […]
