The Climber' is one of those manga that feels like it never got the attention it deserved outside Japan, but luckily, there are ways to track it down online. I stumbled upon it a while back when I was deep into sports manga, and its focus on rock climbing hooked me instantly. For legal options, check out platforms like Kodansha's official digital library or ComiXology—they sometimes have older, niche titles like this. If you're okay with fan translations, sites like MangaDex might have it, but availability varies since scanlation groups come and go.
Just a heads-up: because it's a bit obscure, you might have to dig through aggregator sites, but I'd always recommend supporting the official release if possible. The art in 'The Climber' is stunning, especially the way it captures the tension of scaling cliffs, and it'd be a shame if the creators didn't get credit for their work. Last I checked, there wasn't a complete English release, but Kodansha has been slowly bringing older gems to digital platforms, so fingers crossed!
