Self-introduction… It isn’t good to write a sentence to be honest.


Tetsu Otter

The name “Tetsu Otter” began to be used in August 2015. Origin of that name comes from the name “鉄道好きのかわうそ” that I used before I started using the name “Tetsu Otter”(around April 2015).
So, I will talk about the origin of the name “鉄道好きのかわうそ”. Origin of this name begins with love at first sight of that pretty appearance of Small-clawed Otter who was in Miyajima Aquarium in Hiroshima Prefecture which I went to on the school trip in junior high school 3rd year. It’s cute, isn’t it? Isn’t it??
I came up with a name called “鉄道好きのかわうそ” from such a strange idea, that “If they would be interested in and love railroads, what they will do?” And, if this name shorten, it will be “鉄かわうそ”. And as a result of making it a bit cool, the name “Tetsu Otter” was born.
By the way, we shorten the name “Tetsu Otter” to “TR”.






Tech Otter

This is the explanation of the name of this homepage. The origin of this name is, simply, to add “Tetsu Otter” and “Technology” and divide it into two. In first, I thought that “Otter Technology” was good, but that’s too long, so I came up with the name “Otter Tech”, in second. However, it is hard to say it, so it finally became the name “Tech Otter”.
By the way, the name “TRtec” simply means “Tech Otter” shortened to “TR” where I added “tec” as a Tech element.
