When is the Japan legislative election 2028?

Polling day is 2028-07-23, not yet officially confirmed.

When will the final result of the House of Councillors (regular election, half the seats) race be official?

Expected between 2028-07-26T01:00:00Z and 2028-07-31T14:59:59Z (UTC), confidence precedent. Constituency winners are proclaimed by each prefectural election commission once its election meeting has determined them (art. 101-3). The national PR winners are fixed at the PR election meeting, held on the day the returning officer has all prefectural reports or the next day (art. 81(1),(2),(4)), reported to the Central Election Management Council, which notifies and proclaims them (art. 101-2-2); election takes effect from the proclamation (art. 102). Precedent: 2022 (10 Jul vote) and 2025 (20 Jul vote) the Council received the PR result and decided the proclamation on the Friday after polling day, day 5: 15 Jul 2022 and 25 Jul 2025, with certificates handed over at 13:00 JST (MIC press releases 01gyosei15_02000329 and 01gyosei15_02000457); in 2025 the Council had fixed the election meeting for 25 Jul 10:00 JST already on 4 Jul (01gyosei15_02000452), and MIC's 結果調 was dated 'R7.7.25発表'. On a 23 Jul 2028 polling day that points to Fri 28 Jul 2028. The opening (10:00 JST Wed 26 Jul, day 3) is an ESTIMATED floor; the window closes at the end of Mon 31 Jul JST, three days past precedent. Election suits go to a High Court within 30 days (art. 204, 208); no court must confirm the result, so no court-validation stage.

Where are the official House of Councillors (regular election, half the seats) results?

precedent

Polls close at 20:00 JST (Public Offices Election Act art. 40: '投票所は、午前七時に開き、午後八時に閉じる'; a municipal commission may close up to four hours earlier, so some polls close before 20:00); Japan has no daylight saving time, so 11:00 UTC. Counting starts on election night. 2025 precedent: MIC's release page (soumu.go.jp/senkyo/27sansokuhou/) published PR interim counts hourly from 23:00 JST Sun 20 Jul; the 11:00 JST Mon 21 Jul sheet (第13回) shows 開票率 99.6% and the 16:00 JST sheet (第18回) 100.0%, matching the posted 開票結果. MIC's pre-election timetable (投・開票結果判明予定日時) planned the last constituency count to end at 05:00 JST (Tokyo) and the last PR count at 07:00 JST Mon. The window closes at 18:00 JST Monday, two hours past the 2025 precedent. Constituency counts appear on the 47 prefectural commissions' sites. These are count results, not the proclamation of winners.
