Small scale fireworks festival near Okutama Station with just 1,000 fireworks released (versus upwards of 13,000 for the major Tokyo firework events). That said, it’s one to consider if you want to enjoy a firework event without fighting your way through crowds. Okutama Station is about two hours from Shinjuku Station (Chuo Line to Ome then change to the Ome Line).
