Top developments
Mount Fuji: congestion persists despite regulation; Environment Ministry review ahead
Yomiuri reported (Sept 21) that climbers chasing the sunrise are still flooding the summit even after rules were introduced, with fears of falls triggering "domino" falls on congested trails near the top; Japan's Environment Ministry will now review and verify the effectiveness of the regulations. A separate piece from YAMATOMO Magazine (Sept 23) warns that despite the official closure of the 2026 climbing season, "last-minute summit rushes" are being advertised in Japan — noting the 2026 rules: ¥4,000 entry fee and pre-learning requirement on Shizuoka's three trails, and a ¥4,000 toll plus a 4,000-per-day cap on the Yoshida Route.

This weekend's ultra calendar: Bear 100, Cowboy 200, Vermont 50
This weekend (Sept 26-27) features 100-mile fixtures including the Bear 100 (UTMB-index–eligible style point races), the Cowboy 200, plus the Hinson Lake 24 Hour, Vermont 50 and Rockcut Race Weekend — key late-season chances for runners to bank qualifying distances and ranking points ahead of 2027 lottery and qualification windows.

iRunFar's trail and ultra recap for Sept 21 leads with the Skyrunning World Championships, a top-tier result inevitably feeding into championship selection and rankings conversations as the northern autumn race season ramps up.

Amer Sports raises Q3 outlook on Salomon/Arc'teryx footwear
On Sept 21, Amer Sports — parent of trail-running heavyweight Salomon and Arc'teryx — raised its third-quarter revenue outlook, now expecting sales growth of 20% to 22% year over year, with footwear momentum at both brands cited as the growth engine. For hikers and trail runners, that signals continued shelf presence and investment in premium trail footwear through the fall season.

Local view
Japan: Yomiuri's Fuji coverage is the dominant national-angle story, framing the sunrise rush as a safety problem the fee-and-cap system has not solved. Japanese trail site Trail Runner.JP (Sept 24) published its weekly round-up of closed and congested hiking trails and is live-tracking the Shin-etsu Five Mountains Trail Running Race 2026 with live streams, results and GPS.
Korea: The 2026 Seoul International Ultra Trail Running Race (Seoul 100K) ran Sept 19-20, linking central Seoul, Inwangsan, Bukhansan and the Han River, with around 2,000 runners including 170 from 36 countries, per local outlet KMKJ. Segye-style analysis at Keyzard notes the 20K/50K/100K course includes "walk-only" shared sections in Bukhansan National Park to reduce conflict with hikers. Separately, Newspim (Sept 19) reported Korea's national park character merchandise has generated 3.1 billion won in sales, averaging 209 items sold per day.
