In Bali you don't day-trip from the island — you day-trip within it, from your base. Four kinds — the temples, the rice terraces, the volcano and waterfalls, and the Nusa islands — how to reach each, and how to pick.

Singapore is compact, so its day trips are the islands and a border hop. Four kinds — the resort island, the rustic one, the quiet Southern Isles, and Malaysia or Indonesia for the day — how to reach each, and how to pick.

Osaka is the best day-trip base in Japan — the deer, the castle, the temple mountain, an old capital, all a short train away. Which to do, and how far each really is.

The city is two or three days; the day trips fill out the rest. Four kinds — the icon, the islands, the hikes, and the close half-days — and how to pick.

Bangkok is three or four days; the day trips fill out a longer stay. Four kinds — the ruined old capital, the markets on the water and the tracks, the war history, and the wild — how to reach each, and how to pick.

Taipei is three or four days; the day trips fill out a longer stay. Four kinds — the northeast gold towns, the north coast, the mountains and the big gorge east — how to reach each, and how to pick.

Seoul is three or four days; the day trips fill out a longer stay. Four kinds — the border, the scenery, the history and the family day — how to reach each, and how to pick.

Kamakura, Hakone, Nikko, Yokohama, Kawagoe — ranked by what you get back for the day it costs, with the two that work as a half-day.

KL is two days; the day trips fill out a longer stay. Four kinds — the UNESCO old town, the cool highland escapes, the wild, and the garden capital — how to reach each, and how to pick.

Kyoto reaches the same Kansai greats as Osaka, plus a couple of its own quiet ones — tea-town Uji and the mountain temples. Which to do, and how far each really is.
