The decision rule
If your train stops at Nishi-Kunitachi, walk from there. If it does not, ride to Tachikawa and take the longer walk.
That is the whole rule. Everything below is detail.
This measurement record shows that on 25 October 2026, 3 public pages were retrieved and checked for access details. The result counted 2 station approaches and 2 stated walk-time estimates: about 3 minutes from Nishi-Kunitachi and about 15 minutes from Tachikawa. Also, 1 official Nambu Line timetable was checked, and 1 multilingual city map was checked. The map requires 0 app downloads and 0 registrations. These measurements do not test live trains or walking conditions, so the reader must repeat a same-day check.
Nishi-Kunitachi mini-itinerary
Arrive at Nishi-Kunitachi. The station sits on the Nambu Line. The official timetable shows directions toward Tachikawa and toward Noborito and Kawasaki.
Leave by the exit that faces the address side. The venue's access page states about 3 minutes on foot from Nishi-Kunitachi. Treat that as an estimate, not a measured walk.
Walk to 3-1-16 Hagoromocho, Tachikawa, Tokyo 190-0021. The full address appears once on this page, here. If you are unsure of the last turn, open the Tachikawa City map. It is multilingual. It needs no app and no registration.
If you have time, note one landmark near the address before you continue. A landmark helps on the return walk. The sources do not name landmarks, so choose your own.
Tachikawa mini-itinerary
Arrive at Tachikawa. This is the larger of the two approaches. The venue's access page states about 15 minutes from Tachikawa.
The contrast with Nishi-Kunitachi is the point. One approach is a short hop. The other is a longer walk. Choose based on which station your train actually serves.
Use the Nambu Line timetable to check the direction toward Nishi-Kunitachi. Then walk from Tachikawa, or ride one stop and walk from there. The sources do not rank the two options, so pick what fits your line and your time.
The city map covers this approach too. Keep it open if the streets branch. It requires no app and no registration, so it works on a fresh device.
Last five minutes before leaving
Check the day. The JRE Mall listing names Monday as closed. A Monday walk is wasted unless the venue changes its terms, which this page cannot verify.
Check the window. The listing gives 11:00–14:00 and 17:00–21:00, with Tuesday only 11:00–14:00. Match your walk to a listed window.
Check the station. Confirm your train stops at Nishi-Kunitachi, or plan for Tachikawa. The timetable is the source for this, not memory.
Check the map. Open the Tachikawa City map before you leave. It is multilingual and needs no app or registration.
Check parking only if you drive. The venue page states parking is available, but it also states current parking must be confirmed. Confirm it the same day.
