Start at Tsukiji Outer Market around 10:30–11:00, when the narrow lanes are still lively but the earliest breakfast rush has eased. Browse the tamagoyaki stands, dried seafood shops, and small counters, then settle in for a sushi or seafood brunch—allow roughly ¥2,000–¥5,000 per person. Most stalls trade from about 8:00 until early afternoon, and cash is still useful; avoid bringing large luggage, as the lanes are tight. From Tsukiji to Hamarikyu Gardens, walk about 15 minutes or take a short taxi ride.
Spend around 1½ hours in Hamarikyu Gardens, an Edo-period landscape of ponds, bridges, and quiet paths surrounded by modern towers. The garden generally opens at 9:00 and admission is about ¥300; the traditional teahouse is a good place for matcha and a short rest, especially in August. Walk or take a taxi toward Azabudai Hills—allow approximately 20–25 minutes on foot, or 10 minutes by taxi in the heat. Your timed entry at teamLab Borderless is best treated as fixed: arrive 15–20 minutes early, and reserve tickets online in advance. Plan about two hours inside, wearing comfortable shoes and avoiding bulky bags; the dark rooms, mirrors, and interactive floors are much more enjoyable without a rushed schedule.
After teamLab Borderless, walk a few minutes to Tokyo Tower for the late-afternoon transition into sunset. The Main Deck is usually open into the evening, with admission commonly around ¥1,200–¥1,500; check the exact sunset-day ticket availability and weather before going, since clear skies make a dramatic difference. Allow 1–1½ hours, including the surrounding viewpoints at Zojoji Temple if you want a quieter alternative to the observation deck. Finish at 麻布台ヒルズ マーケット (Azabudai Hills Market), where you can pick up prepared Japanese dishes, sushi, fruit, or snacks for a casual dinner—budget about ¥2,000–¥4,000 per person. It is a convenient, air-conditioned end to a hot August day; check the market’s current closing time before setting out, as individual counters may close earlier than the main complex.
