Koganei
小金井市
Spend half a day in Koganei to see the Open‑Air Architectural Museum and the park; add a quick ramen stop if time permits.
Koganei, a western Tokyo suburb, is reachable in ~30 min by JR Chuo from Shinjuku. Its main attractions – the Edo‑Tokyo Open Air Architectural Museum and the large Koganei Park – are close together, making a half‑day visit feasible. Add a ramen shop for a quick meal; one night is unnecessary unless you prefer a relaxed pace.
