秋川渓谷に日帰りラボ旅行 / One-day Lab Trip to the Akigawa Valley

　2023年以来、３年ぶりに秋川渓谷にマス釣り＋BBQと大岳鍾乳洞の日帰りラボ旅行に行きました。３年前はものすごい暑さの中、こっちも暑いけど研究所よりはまだマシ、という感じだった記憶です。その後、2024、2025年もまたさらに輪をかけたような暑さでした。ところが、今年はエアコンなしでも寝苦しい夜はそんなになく、太陽が出ている日も少なく、かなり楽な夏だったと思います。最近がずっと暑過ぎたせいで、私が子供の頃はこんな感じだったんだろうか、とかもう思い出せなくなってしまいました。まあ確かに、夏休み終わって死ぬほど暑い、って記憶もなかったような気もしますし、そもそも小中高と教室にエアコンがなくても、暑いなりに学校生活は送っていたということは、こんな感じだったのかもしれません。

　話が逸れましたが、またみんなでニジマスを釣って、焼いて食べました。肉も飲み物も買って行ったので、十分な量があったと思います。３年前と同じように鍾乳洞にも行けました。２回目の人もいれば、初めての人もいて、入れ替わりを感じました。参加する子供が増えたのも賑やかになってよかったです。

　３年前の教訓から、氷はそこまで必要ないとか、タープは持っていく必要ない、とか覚えていたのですが、大きい焼き網が必要、ということをすっかり忘れていました。次は備えます。ラボ全員が参加できたのは素晴らしいことでした。良い息抜きにしてもらって、研究進めてくださいませ。

For the first time in three years—since 2023—We went on a one-day trip with the lab to the Akigawa Valley for trout fishing and a BBQ, followed by a visit to the Odake Cave. I remember that three years ago, it was an incredibly hot summer, but I felt like, “It’s hot here too, but it’s still better than the lab.” After that, the heat in 2024 and 2025 seemed to have gotten even worse. However, this year there weren’t that many sleepless nights even without air conditioning, and there were fewer sunny days, so I think it was a pretty OK summer. Because it’s been so unbearably hot lately, I’ve actually lost the ability to recall whether this is what it was like when I was a kid. Well, come to think of it, I don’t seem to have any memories of it being unbearably hot right after summer vacation ended. And since I went through elementary, middle, and high school without air conditioning in the classrooms—managing school life despite the heat—maybe this is what it was actually like. Maybe.

　I digress, but we all went fishing for rainbow trout again, grilled them, and ate them. We brought meat and drinks with us, so I think we had plenty. Just like three years ago, we were also able to visit the limestone cave. Some people were there for the second time, while others were first-timers, and I could really feel the turnover in the group. It was great that more kids joined in—it made things livelier. 　Based on the lessons learned three years ago, I remembered that we didn’t really need that much ice or a tarp, but I completely forgot that we needed a large grill. I’ll make sure to bring one next time. It was wonderful that everyone from the lab was able to participate. I hope you all enjoyed this nice break and will continue to make progress on your research.
