Tokyo, Hakone & Mount Fuji with kids
City then mountains: four nights in Tokyo, then two in Hakone for the hot springs, the pirate-ship lake cruise and Mount Fuji views - a nature-and-onsen finish that little legs love.

Where to stay
Sheraton Grande Tokyo Bay Hotel · Maihama, Urayasu (Chiba) - Check availability on Booking.com · more family stays
To Hakone: ~1h 30m by train - Odakyu Romancecar runs direct from Shinjuku to Hakone-Yumoto in about 85-90 minutes; the Hakone Free Pass then covers the local mountain transport loop. Not on the JR Pass.
Arrival & rest days
Keep day one in Tokyo gentle - clear immigration, pick up IC cards and pocket Wi-Fi, and do something low-key near your hotel rather than a headline attraction while everyone is jet-lagged. Over 6 nights, build in a slow morning or a pool/park afternoon every second or third day so the trip doesn't run the children down.
If it rains - and what not to combine
Don't chain two big-ticket days back to back (e.g. a full theme-park day straight into a long shrine walk). Keep a wet-weather swap per city - an aquarium, a hands-on museum or a covered arcade - so a rainy morning doesn't derail the plan; the planner suggests indoor alternatives by your dates and your children's ages.
Book these before you lock in dates
Several family favourites on this route sell out well ahead and some release on a fixed date and time. Check the attraction booking calendar and work your dates around the hardest ticket, then reserve shinkansen seats together (and any oversized-luggage spaces) once your legs are set.
Adapting the pace: with under-5s, add a slow morning or a pool afternoon every second day and don’t chain two big-ticket days together; with teens you can tighten transfers and add an extra evening out. The planner rebalances nights, pace and each day’s plan around your children’s ages - this template is the starting point, not a fixed schedule.
