Is Life Just a Way to Pass the Time? Or Is It About Making Memories? | The Rewards of Slope Stabilization Work I Discovered During Disaster Recovery Efforts for the Chuetsu Earthquake

Hello, everyone. This is Enta. The other day, I took a little trip to the Ogasawara Islands to check out what’s coming up. It’s such a beautiful, off-the-beaten-path island—it felt like I was back on one of the islands off the coast of Kagoshima for the first time in a while, lol. But enough of that. This time, I’d like to step away from tech for a bit and talk about life and work. Life is a grand adventure…

The Real Reason Mountains Collapse Due to Mega-Solar Projects: Examining the Truth Through the Theory of Pseudo-Retaining Walls in Reinforcing Bar Installation and On-Site Drainage Risks

Hello, everyone. It's Enta here. I kept adding to this as I researched various things, and it ended up getting super long... So please read this when you have some free time lol. I kept thinking, "This is so loooong!" as I was writing it lol. It might get a bit disjointed in parts, so just take it as a joke this time. And lately, the general...

Are Decisions Made in 10 Seconds the Same as Those Made in an Hour? | A Slope Engineer’s Superficial Take on the “First Chess” Theory

Hello, everyone. This is Enta. Things are finally starting to get a little busy, aren’t they? It seems like the busy season gets shorter every year... But enough of that. Today, I want to talk about “the time we spend making decisions.” What’s the difference between a decision made in 10 seconds and one made after an hour of careful consideration?

Collusion and Business Risks Resulting from Reliance on a Single General Contractor | How Specialized Construction Companies Can Diversify Their Business Partners

Hello, everyone. This is Enta. The mornings and evenings have gotten quite cool, and it’s finally starting to feel like fall. It looks like our heatstroke prevention measures on the job site will be wrapping up soon, too ^^ But enough about that. Last time, I discussed the legal risks a subcontractor faces when a general contractor’s representative offers a kickback, as well as how to refuse…

How to Clean a Well | Causes of Clogs and Steps for Internal Cleaning Using Air and Water

Hello, everyone. This is Enta. When I’m working on drilling jobs, I occasionally get requests like, “Take a look inside this well.” I usually drill holes for slopes and anchors, but in terms of working with pipes in the φ50 to φ100 range, wells are actually quite similar. …

Stay Alert in the Mountains for 1–2 Weeks After Heavy Rain | An Article for the General Public on “Soil Doesn’t Dry Out Easily”—What You Need to Know Before Silver Week

Hello, everyone. This is Enta. It’s been raining on and off for the past few days, hasn’t it? Plus, Silver Week starts this weekend (in 2026, it’s a five-day holiday from September 19 to 23). I bet there are quite a few people thinking, “It’s been a while since I’ve had a long weekend—maybe I’ll head to the mountains.” Oh, and for us slope maintenance workers, it’s business as usual…

90-Minute Seminar at the Architects Association | Why Retaining Walls Can Be Used in Slope Stabilization Projects, and the Invisible Barrier Between Architecture and Civil Engineering

Hello, everyone. This is Enta. The other day, I had the opportunity to give a seminar at the Tokyo Association of Architects. The theme was “Mountains, Ground, and Retaining Walls,” and I ended up talking for a full 90 minutes (lol). To be honest, the architecture world is usually pretty far removed from our line of work as slope engineers. So…

I Listed All of Japan's "○○-ya" Businesses | Differences in Specialization Between Japan and Overseas, as Seen by Slope Construction and Reinforcing Steel Contractors

Hello, everyone. This is Enta. In my last post, I wrote a brief article introducing “○○-ya,” but I received feedback saying, “I want to know everything about it” and “Don’t leave out the international locations.” You’re absolutely right. If I only highlight a partial, incomplete picture, it actually makes people wonder, “This is included, but what about that…?”

Over 1,000 Landslides Occur in Japan Each Year | Why They Don't Cause Major Damage

Hello, everyone. This is Enta. There are only a few days left in August. Let’s keep up the momentum! But enough of that—let me start with a somewhat serious topic today. A massive mudslide in Nepal—possibly triggered by a collapsing glacier—amid high temperatures in the surrounding area. On August 26, in Nepal and Central…
