Japan is the most-planned trip that never gets booked. People circle it for years — too far, too expensive, too complicated. None of those are as true as they feel. Here’s the realistic version of planning a first trip from the UK: what actually matters, what doesn’t, and the one detour I’d beg you to add.
Flights and When to Go
Direct flights run from Heathrow to Tokyo in roughly 13-14 hours (British Airways and Japan Airlines both fly the route), with one-stop options via the Gulf or Helsinki often meaningfully cheaper. The sweet spots are late March–April (cherry blossom, busy, magical) and late October–November (autumn colour, fewer crowds, my pick). Avoid Golden Week (late April–early May) unless you enjoy queuing with the entire nation, and know that June–August is beautiful but seriously hot and humid.
UK passport holders currently enter visa-free as tourists for short stays — but entry rules are the one thing you should always verify against official sources close to travel, because they do change.
The Route
For a first trip of 10-14 days, the classic shape works because it’s genuinely good: Tokyo (4-5 days) → Kyoto (3-4 days) → Osaka (2 days), connected by shinkansen. Add day trips — Nara from Kyoto, Nikko or Kamakura from Tokyo — as energy allows.
And here is my one heartfelt amendment: take the extra travel day and add Nagasaki. It’s the city where Europe and Japan first met, where Portugal’s 70-year chapter is still visible in the churches, the trading island of Dejima, and the castella bakeries. I’ve written a full guide to Nagasaki’s Portuguese trail — for readers of this site, it turns a great trip into a pilgrimage.
Trains and the JR Pass Question
The Japan Rail Pass used to be an automatic yes; after its major price rise it’s now a calculation. Rough rule: if your itinerary is Tokyo-Kyoto-Osaka and back, individual shinkansen tickets often come out cheaper. If you’re adding Kyushu (hello, Nagasaki) or bouncing across the country, the pass can still win. Price both before you buy — regional passes are frequently the smarter deal.
Inside cities, get an IC card (Suica or Pasmo — both now load straight into Apple Wallet) and tap your way through everything: trains, buses, vending machines, convenience stores.
Money and Connectivity
Japan is far more card-friendly than its reputation, but cash still matters at small restaurants, shrines and markets — 7-Eleven cash machines accept UK cards and are everywhere. For data, an eSIM ordered before you fly is now the cleanest option; pocket wifi routers remain good for couples and families sharing a connection.
🧳 The travel kit that earns its place
[Replace with AAWP boxes — cabin-approved luggage, a plug adapter (Japan uses Type A), a good eSIM or pocket wifi option, and a portable battery. Travel gear is a strong affiliate category — keep recommendations tight and personal.]

The Mindset Notes
Book accommodation early for blossom and autumn seasons; everything else can stay loose. Learn five phrases — they’ll be received warmly. Carry a small bag for your rubbish (public bins are rare). And plan less than you think you should: the best parts of Japan are the unplanned hours between the itinerary items — the backstreet, the tiny bar, the bakery selling pan, a Portuguese word that’s been waiting there for 400 years.
