1 · 路線基本

1 · The route, basics

A · 爆偈同學
  • 全程約 200 公里，日本官方認定的國家級單車道之一。
  • 距離概念（以香港比較）：由馬鞍山踩到屯門約 60 公里，即環琵琶湖一週 ≈ 踩三轉馬鞍山到屯門。
  • 建議天數：官方建議至少兩天一夜；作者採三天兩夜；高手可一天完成。
  • 「新手」定義：平時有踩單車，但未必有長途經驗。
  • 大部分路段舒服好踩，難處在於：少量山路 ＋ 一段比較迫的馬路。
  • About 200 km, one of Japan's designated National Cycle Routes.
  • Scale for a Hong Kong rider: Ma On Shan to Tuen Mun is about 60 km, so one lap ≈ three of those.
  • Days: officially at least two days, one night; he took three days; strong riders manage one.
  • His "beginner" means someone who rides, but not long distances.
  • Mostly comfortable. The hard parts are a little mountain road and one cramped stretch of highway.
B · Med日跑者
  • 位置：滋賀縣，約在京都東北方。大津從京都搭車不到 15 分鐘。
  • 規模：日本最大湖泊，面積約 670 平方公里（約台北市兩倍），周長約 200 公里。
  • 季節：最推薦初春或初秋——氣候溫和，且白天夠長，方便日間騎乘。
  • Where: Shiga Prefecture, north-east of Kyoto. Otsu is under 15 minutes from Kyoto by train.
  • Size: Japan's largest lake, about 670 km² (twice the area of Taipei), shoreline about 200 km.
  • Season: he most recommends early spring or early autumn — mild, and with long enough days to ride in daylight.

2 · 方向：兩人都說逆時針

2 · Direction: both say anti-clockwise

A · 爆偈同學
  • 日本右軚車、靠左行駛，踩單車也靠左。
  • 踩左邊＝逆時針：湖會靠你近很多、壯觀很多。
  • 若順時針：對面線有單車迎面而來，湖在右邊還隔一條馬路，絕對影響觀感。
  • Japan drives on the left, and so do bicycles.
  • Riding on the left = anti-clockwise, which puts the lake far closer and more impressive.
  • Clockwise means oncoming bikes, and the lake on your right with a road in between — it spoils the view.
B · Med日跑者

他實際踩順時針，但建議逆時針，理由與觀感無關：

He rode clockwise and recommends anti-clockwise — for reasons that have nothing to do with the view:

  • 湖東較熱鬧、便於採購：第一天若需緊急採購，彥根、米原是都會區。
  • 住宿較好找：大津往彥根、米原方向約 70K 好找房；順時針 70K 處較偏鄉，難找。
  • 最後一天更輕鬆：雄琴、近江今津距大津僅約 40K，把最後一晚放這裡，隔天很寬裕——不像他要從彥根一路推回大津。
  • The east side is busier — if you need something urgently on day one, Hikone and Maibara are proper towns.
  • Rooms are easier: Otsu towards Hikone/Maibara at ~70 km has beds. Clockwise, 70 km lands in the countryside.
  • An easier last day: Ogoto and Omi-Imazu are only ~40 km from Otsu. He had to grind back from Hikone instead.

兩人同一結論，理由完全不同——一個為景觀，一個為後勤，而且 B 是踩錯方向之後才這樣說的。兩條互不相干的論證指向同一答案，比單方面的建議可信得多。

Same conclusion, entirely different reasoning — one for the view, one for logistics, and B only says it having ridden the wrong way. Two independent arguments reaching one answer is far stronger than either alone.

3 · 路況、導航與危險路段

3 · Road conditions, navigation, the dangerous bits

官方五種路況顏色分類〔A〕The official five-colour road classification, per A
顏色Colour路況What it means
藍色Blue幾乎全程見湖、易踩。左邊是湖、右邊是馬路，中間供跑步與踩車。平原、城市少、紅綠燈少。有很多上上落落但不辛苦。Lake in view, easy going — lake left, road right, a shared strip between. Flat, few towns, few lights. Many small ups and downs, nothing punishing.
綠色Green看不到湖。多以隧道穿越，有行人路但較迫。（國家級公路的隧道沒那麼窄。）No lake view. Mostly tunnels; there is a footway but it feels tight. Tunnels on the national route are less narrow.
橙色Orange山路。全程最辛苦的一段，但滑下去那刻特別爽。Mountain road. The hardest part of the loop — and the descent is the sweetest moment.
紫色Purple穿越小路，小山路較多，接近小野一帶。車輛會禮讓行人與單車。Back lanes with more small climbs, around Ono. Drivers give way.
紅色Red尚未完善。由高島市開始一直如此。與汽車共道、窄到不得了，需不停回頭看後方。作者說下次要裝後視鏡。Not yet built out. Starts at Takashima and continues. Shared with cars, extremely narrow, constant shoulder-checking. He'd fit a mirror next time.
A · 爆偈同學

藍線導航系統

The blue-line system

  • 沿著地上藍色線走，基本上不會迷路。
  • 馬路上的藍線＝上級（標「快速」），供高手；行人路上的藍線＝低速。闊路兩條都有，窄路只剩馬路那條。
  • 藍線消失時別緊張：附近有路牌標「左手邊低速、右手邊上級」，沿行人路繼續踩，前方會再出現。
  • 路牌右上角有單車牌＝可在行人路踩，但必須禮讓行人。
  • Follow the blue line and you basically cannot get lost.
  • On the carriageway = the "advanced" line (marked express); on the footway = the slow line. Wide stretches have both, narrow ones only the carriageway.
  • Don't panic when it vanishes — a sign marks slow-left / advanced-right. Continue on the footway and it reappears.
  • A bicycle symbol top-right of a sign means the footway is allowed, but yield to pedestrians.

安全提醒：日本人開車一般很有禮貌，已習慣大量騎單車人士；但紅色線窄且與汽車共道，香港平時有單車徑、缺乏馬路併行經驗的人要特別小心。

Safety note: drivers are courteous and used to cyclists, but the red section is narrow and shared. Riders used to segregated paths need care.

B · Med日跑者

實際騎乘規則

Riding rules in practice

  • 多有腳踏車專用道，將單車與汽車隔開。
  • 人行道原則不能騎。馬路左側的藍色線或腳踏車標誌，才是單車該走的位置。
  • 日本駕駛守規矩：超越時基本保持一到兩個車身寬度，較少被「刷卡」。
  • 危險路段：北邊偏鄉大車多、車速快，有些會刷卡，須隨時注意車後。
  • 人行道有藍色標誌、寫「腳踏車通行可」才可騎，且要放慢禮讓行人。
  • Mostly dedicated lanes, separating bikes from cars.
  • Footways are off-limits by default. The blue line or bike symbol on the left of the carriageway is where you belong.
  • Drivers behave — generally one to two car widths when overtaking.
  • The dangerous bit: the rural north has more fast lorries, some passing close. Keep checking behind.
  • Only ride a footway marked "bicycles permitted", slowly, yielding to pedestrians.

官網提醒：湖西側「大津 近江舞子以北」——即他 Day 1 的路線——腳踏車道設施較缺乏，往往需騎到馬路上，且馬路不寬。

The official site flags: on the west shore north of Omi-Maiko — his Day 1 — facilities thin out, you end up on the carriageway, and it isn't wide.

兩人點名的危險路段是同一段。A 說「紅色線由高島市開始」，B 說「近江舞子以北設施缺乏」——都在湖西。西岸是這條路線唯一需要真正提防的地方。

Both single out the same stretch. A's "red section from Takashima" and B's "thin facilities north of Omi-Maiko" are both on the west shore. That side is the one place on this route needing real caution.

4 · 實際路線與分段

4 · The routes, and how to split the days

同一個湖，兩個相反方向，都用三天。切換地圖看差別。

Same lake, opposite directions, three days each. Switch the map to compare.

A · 爆偈同學
  • 逆時針，三天兩夜：Day 1 大津 → 長濱；Day 2 長濱 → 高島；Day 3 高島 → 大津。
  • 大件行李寄存酒店，三天只背一個揹包。
  • Anti-clockwise, three days: Day 1 Otsu → Nagahama, Day 2 Nagahama → Takashima, Day 3 Takashima → Otsu.
  • Big luggage stays at the hotel; three days on one backpack.
B · Med日跑者
  • 順時針，三天兩夜，前一晚先住京都市區，早上搭 JR 到大津取車。
  • Day 1（45K）：大津 → 近江神宮 → 雄琴溫泉 → 浮御堂 → 白鬚神社 → 夜宿牧野。
  • Day 2（75K）：先繞水杉林蔭大道（メタセコイア並木）→ 永源車站 → 長濱城 → 夜宿彥根。
  • Day 3（70K）：彥根城 → 近江牛瘦肉壽喜燒 → 往南回大津，趕在下午 5 點店家關門前還車。
  • 對好手是輕鬆的單日長度，甚至可縮成兩天一夜；但他是單車小白又想看景點，所以抓寬裕的三天。
  • Clockwise, three days, staying in central Kyoto the night before and taking the JR to Otsu in the morning.
  • Day 1 (45 km): Otsu → Omi Jingu → Ogoto onsen → Ukimido → Shirahige Shrine → overnight at Makino.
  • Day 2 (75 km): the Metasequoia avenue → Eigenji station → Nagahama Castle → overnight in Hikone.
  • Day 3 (70 km): Hikone Castle → Omi beef sukiyaki → south to Otsu, returning the bike before the shop shuts at 5pm.
  • Easy single days for a strong rider — could be two days — but he was a beginner who wanted to see things, so he allowed three.

路線圖：切換兩人的走法

4b · Day splits: 2 / 3 / 4 days, or the 150 km north lake

切換天數看每日路段。四個打卡區（湖南／湖東／湖北／湖西）標在地圖四邊——每區只要打一張卡。也可以只繞北湖：在琵琶湖大橋抄捷徑，全程縮短到約 150 公里。

Switch the number of days to recolour the route. The four check-in zones are labelled around the edge — one card in each is all you need. You can also ride the north lake only, cutting across the Biwako-Ohashi bridge for about 150 km.

一句講完

In one line

全湖有 16 個打卡點，分佈在四個區。你要做的是每區至少打一個——最少四次，在 16 個點裡揀順路的就可以，打多了無妨。四區打齊，「申請」按鈕才會出現。 There are 16 checkpoints around the lake, spread across four areas. You need at least one in each area — four checks minimum — choosing whichever of the 16 are convenient. Extra ones do no harm. The apply button appears once all four areas are done.

一次打卡實際怎樣做

What one check-in actually involves

官方流程

The official flow

  • 出發前先開帳號：到 m.biwako1.jp 按「新規登録」註冊。沒有帳號不能打卡。不用下載 App，用手機瀏覽器就可以。
  • 到了打卡點：現場有一張寫著問題的海報。
  • 按「チェックする」（檢查）。
  • 系統先用 GPS 定位確認你真的在現場。
  • GPS 失敗的話，掃海報上的 QR code 作後備。
  • 答海報上的問題。答錯可以重試，系統只記錄你答對的那次。
  • Open an account before you go at m.biwako1.jp via 「新規登録」. No account, no check-in. No app needed — a mobile browser is enough.
  • At the checkpoint there is a poster with a question on it.
  • Press 「チェックする」 (check).
  • GPS confirms you are physically there.
  • If GPS fails, scan the QR code on the poster as a fallback.
  • Answer the question on the poster. Wrong answers can be retried; it records the one you get right.

兩條最容易被忽略的規則

The two rules most easily missed

兩者都會直接改變你的規劃

Both change how you can plan

  • 1. 沒有時間限制。官方原文：「最初のチェックから最後のチェックまでの日数に制限はありません」——第一次打卡到最後一次打卡之間沒有日數上限，可以分幾次、隔幾個月甚至幾年完成，不必一趟過踩完。
  • 2. 可以由任何一個打卡點開始。不一定要從大津或守山出發。
  • 1. There is no time limit. Officially, there is no limit on the number of days between your first check and your last. You can do it in pieces, months apart, even across years — you do not have to ride the loop in one go.
  • 2. You can start at any checkpoint. It does not have to be Otsu or Moriyama.
有用Useful 若第一次去只踩得到一半（天氣、體力、時間），已打的卡不會作廢，下次補回其餘的區就可以申請。這大幅降低了「一定要一次踩完」的壓力。 If a first trip only gets you halfway — weather, legs, time — the cards you already have do not expire. Come back, fill in the remaining areas, and apply. That removes most of the pressure to finish in one go.

關於爆偈同學那句「11:03 資訊有誤」

About 爆偈同學's "the information at 11:03 is wrong"

他在 2026 年 5 月依官方條款更正了認證規則，叫觀眾跳過 11:03、直接看 15:10，但沒有說原本錯在哪裡。本節寫的就是現行官方規則——影片（或任何攻略）與此不符時，以官方為準。留意：官方英文網站沒有認證資料，本節內容全部來自日文版頁面。 In May 2026 he corrected the certification rules against the official terms, telling viewers to skip 11:03 and watch from 15:10 — without saying what was wrong. This section is the current official rule; where the video, or any guide, disagrees, the official site wins. Note that the English site carries no certification information, so all of this comes from the Japanese pages.
只繞北湖 150 公里的人請注意：只有一種認定證，沒有「北湖版」。湖南區的 5 個打卡點都在南湖一帶，所以抄琵琶湖大橋捷徑會拿不到湖南那張卡。想要證書又想省距離的話，可以利用「沒有時間限制」這一點——另外找一天單獨去南湖補一個湖南打卡就行。 If you ride the 150 km north-lake loop: there is only one certificate, and no north-lake version. All five Kōnan checkpoints sit around the southern basin, so cutting across the Biwako-Ohashi means you never get that card. If you want the certificate and the shorter ride, use the no-time-limit rule — go back another day and pick up a single Kōnan check on its own.

6 · 租車

6 · Renting a bike

兩片列的是同一組三間店，只是譯名不同。合併成一張表，並標明各自租了哪間。

Both list the same three shops under different transliterations. Merged into one table, with who rented where.

店Shop 位置Where 重點Key points 誰用過Used by
Giant Store 守山Moriyama 環湖官方起點；出站要搭公車約 30 分鐘The official start line; ~30 min by bus from the station 在起點開波很有儀式感，車種多但較貴。只能在此還車、交通不便。適合買套裝、住隔壁萬豪者。堅田站有免費接駁巴士，每小時一班，距守山約 15 分鐘車程Starting at the official line has occasion; wider choice but pricier.

Closed fairly often — check it fits your dates B 最想租，可惜已滿B's first choice, was full
A · 爆偈同學
  • 提早預約一至兩星期，太遲熱門車款租不到。
  • 額外裝備要預約時一併填好（馬鞍袋、手機架、坐墊、打氣筒），當天現場才要有機會提供不到；或記下訂單號碼再電郵告知。
  • 異地還車：按「Offsite Return」填 Google Form，選還車地點。
  • 單車基本包含頭燈、尾燈、頭盔。建議加購 ¥880：坐墊、打氣筒、撬胎棒、備用內胎、尾燈、車鎖、一支水。坐墊很重要，長時間騎乘無坐墊會很痛。
  • Book one to two weeks ahead; late and the popular models are gone.
  • Request accessories when booking — saddle bag, phone mount, seat pad, pump. Asking on the day may fail; or note the order number and email them.
  • Offsite return needs an "Offsite Return" Google Form with your drop-off point.
  • Bikes include front light, rear light, helmet. He recommends the ¥880 add-on: seat pad, pump, levers, spare tube, rear light, lock, water. The seat pad matters — long hours without one hurt.
B · Med日跑者
  • 三天兩夜約台幣 3,200 元（BIANCHI VIA NIRONE 7 公路車），他形容「不算便宜」。
  • 租車的人不少，日期敲定就儘早訂。他較晚決定，有空車的店家已少很多。
  • 官方整理網站的一覽表可看到每間店的營業時間、價格、能否甲租乙還、車輛壞掉店家會不會開車來接。
  • About NT$3,200 for three days on a BIANCHI VIA NIRONE 7 road bike — "not cheap", he says.
  • Plenty of people rent; book as soon as your dates are fixed. He decided late and found few shops with stock.
  • The official comparison table shows each shop's opening hours, price, whether offsite return is possible, and whether they'll drive out to you if the bike breaks.

7 · 安全：輪行袋，與差點失溫的一晚

7 · Safety: the rinko bag, and a near-hypothermic night

兩片唯一都用「一定要」形容的東西，就是輪行袋。原因看下面。

The one item both call essential is the rinko bag. The reason is below.

B · Med日跑者

Day 1 的失溫插曲

The near-hypothermia on Day 1

  • 持續下雨 ＋ 推里程的壓力：冒雨續騎，溫度下滑、衣服濕透，穿太單薄的他開始發抖。
  • 只推到白鬚神社：日落前到著名的水上鳥居，但無暇欣賞，匆匆拍照就走——此時距民宿還有 20 多公里。
  • 堅持夜間不騎車：鄉間小路照明差，他把車停在近江高島站，搭 JR 前往民宿。
  • 出站：大風、細雨、漆黑無路燈，手機顯示體感 −1 度；車站距民宿還要走 20 分鐘。
  • 怕失溫：打電話請民宿給當地計程車電話（偏鄉叫不到 Uber），搭車到民宿才結束。當晚泡大浴池很久才回溫。
  • Rain plus the pressure to make the distance. He kept riding; the temperature fell, his clothes soaked through, and dressed too lightly he started shivering.
  • He only reached Shirahige Shrine — the famous torii, before sunset, with no capacity to enjoy it. Over 20 km still to go.
  • He stuck to his no-riding-after-dark rule, left the bike at Omi-Takashima station and took the JR.
  • Outside the station: wind, drizzle, pitch dark, a feels-like of −1°C, and a 20-minute walk still ahead.
  • Afraid of hypothermia, he rang the guesthouse for a local taxi number (no Uber out there). A long soak in the bath before he warmed up.

交通提醒：湖西線末班前後，電車 30–60 分鐘才一班。他的結論：店家有提供輪行袋的話一定要租——體力不支、車輛故障或想提早收工，有袋才能把車帶上電車。

Transport note: late on the Kosei line, trains run every 30–60 minutes. His conclusion: if the shop offers a rinko bag, take it — running out of energy, breaking the bike, or simply stopping early all require one.

A · 爆偈同學
  • 日本鐵路大部分不能直接把單車推上車。需輪袋：把車拆掉、用袋包好扣上，才能抬上鐵路。建議隨身帶著應急。
  • 背負姿勢：扣好胸扣，主要靠腰帶承託，不要長期用肩膀受力——每天可能騎五、六小時。
  • You mostly cannot wheel a bike onto a Japanese train. A rinko bag lets you strip it, bag it and carry it aboard. Worth having.
  • Carrying a pack: chest strap done up, weight on the hip belt, not the shoulders — you may ride five or six hours a day.

8 · 裝備與住宿

8 · Kit and accommodation

A · 爆偈同學
  • 三天兩夜只背揹包，可外掛頭盔。手機防水套 ＋ 外接充電器 ＋ 充電線；包包盡量選防水款。
  • 住宿選官方認證的單車友善酒店，通常提供單車維修、洗衣。
  • 出發前先問酒店能否停泊單車（駐輪場）。
  • Three days on one backpack, helmet clipped outside. Waterproof phone sleeve, power bank, cable; choose a waterproof pack.
  • Stay at officially certified cycle-friendly hotels — usually bike repair and laundry.
  • Confirm before you go that the hotel can store the bike.
B · Med日跑者
  • 軟帽墊在安全帽底下；Frame bag 一套換洗衣服＋牙刷；上管包放手機、行動電源、記憶卡、傳輸線。
  • 御朱印帳（途經多間神社）、托特包（到酒店後逛街用）、騎車腰包（可塞水壺）、防風頭巾、五指手套、變色墨鏡。多用手機支付，只帶一點現金。
  • 當日穿著：T-shirt ＋ 發熱衣 ＋ 短袖外套（京都早上約 12 度，白天 14–15 度）。下身短袖車褲，但他覺得穿長褲會更好。長襪防著涼、防齒輪油與泥沙。
  • Cap under the helmet; frame bag with a change of clothes and toothbrush; top-tube bag for phone, power bank, memory card, cable.
  • Goshuin book (several shrines en route), tote bag for town, waist pack holding a bottle, buff, full-finger gloves, photochromic sunglasses. Mostly phone payments, little cash.
  • What he wore: T-shirt + base layer + short-sleeve jacket (Kyoto ~12°C morning, 14–15°C by day). Shorts — though he thinks long trousers would have been better. Long socks against cold, chain oil and grit.

B 的教訓正好補上 A 沒說的：保暖與防水比裝備清單重要。他自己也說「穿長褲會更好」。

B's experience supplies what A omits: warmth and waterproofing matter more than the gear list. He says himself that long trousers would have been better.

9 · When to go

Med日跑者推薦初春或初秋，理由是氣候溫和且白天夠長——他自己就是在天黑與失溫的邊緣收場的。查證下來這個建議完全站得住腳。

Med日跑者 recommends early spring or early autumn — mild, and with long enough days. He himself finished on the edge of darkness and hypothermia. The research backs him up completely.

滋賀縣。琵琶湖是內陸盆地，冬天湖北下大雪，夏天內陸悶熱。Shiga Prefecture. An inland basin — heavy snow in the north in winter, hot and close in summer.
時段Window 狀況Conditions 評價Verdict 原因Why
3 月下旬 – 5 月Late March – May 10–22°C最佳Best 溫和舒適，櫻花。海津大崎的湖畔櫻並木就在路線上，是關西名所。Mild and comfortable, with cherry blossom. The lakeside avenue at Kaizu Osaki is on the route and is one of Kansai's best.
6 月中 – 7 月中Mid-June – mid-July ~220 mm避開Avoid 梅雨季。七月是全年雨量最高的月份。The rainy season. July is the wettest month of the year.
7 月 – 8 月July – August 常超過 35°C避開Avoid 滋賀夏天常超過 35°C，有中暑風險。內陸盆地不通風。Shiga regularly exceeds 35°C in summer, with real heatstroke risk. An inland basin with little breeze.
9 月 – 11 月September – November 12–26°C最佳Best 紅葉、空氣清爽。但十一月天黑得早——這正是失溫插曲發生的時節條件。Autumn colour and crisp air. But it gets dark early in November — precisely the conditions behind the hypothermia episode.
12 月 – 2 月December – February ~3°C避開Avoid 湖北（長濱以北）常有大雪，一月積雪可達 50 公分。環湖北段基本不可行。The north (beyond Nagahama) gets heavy snow — up to 50 cm in January. The northern arc is effectively out.
建議：4 月或 10 月。四月有海津大崎的櫻花，正好在湖北路段上；十月有紅葉而且白天仍夠長。避開十一月下旬之後——日照變短會直接製造出 Med日跑者那種情況：雨、天黑、體感 −1 度、離住宿還有 20 公里。 Recommendation: April or October. April puts the Kaizu Osaki cherry avenue on your northern leg; October gives autumn colour with days still long enough. Avoid late November onwards — shortening daylight is exactly what produced the Med日跑者 situation: rain, darkness, a feels-like of −1°C, and 20 km still to go.

10 · 怎樣去

10 · Getting there

兩片都沒有講從香港出發的部分。琵琶湖的好處是近——關西機場到大津，一程特急就到。

Neither video covers travelling from Hong Kong. The convenient thing about Lake Biwa is how close it is — one limited express from Kansai Airport to Otsu.

香港 → 關西機場（KIX）

Hong Kong → Kansai (KIX)

與濟州完全相反的情況

The opposite situation to Jeju

  • 每週約 93 班，即平均每日 13 班。航程約 3 小時 45 分。
  • 國泰、香港快運、樂桃、香港航空都有直航——真正有得揀，時間也有得揀。
  • 票價約由 US$111 起。
  • About 93 flights a week — roughly 13 a day. Around 3h45.
  • Cathay, HK Express, Peach and Hong Kong Airlines all fly it — genuine choice, including of departure time.
  • Fares from about US$111.
好辦Easy 不像濟州只有凌晨 02:30 一個時段。這條線可以挑日間航班，帶家人也輕鬆。 Unlike Jeju, where every departure is 02:30. Here you can pick a daytime flight, which matters with family.

租車店所在地

Where the rental shops are

  • JR 特急 HARUKA：關西機場 → JR 大津站約 77 分鐘，單程約 ¥3,000–3,500。持 JR Pass 免費。
  • 或搭 JR 快速在大阪轉車，約 2 小時，較便宜。
  • 大津站 → 湖邊踩單車約 5 分鐘；大津站到京都站只需約 10 分鐘。
  • Med日跑者的做法：前一晚住京都市區，早上搭 JR 到大津取車。京都住宿選擇多得多。
  • JR Haruka limited express: KIX to JR Otsu in about 77 minutes, roughly ¥3,000–3,500 one way. Free with a JR Pass.
  • Or JR rapid changing at Osaka, about 2 hours and cheaper.
  • Otsu station to the lakeshore is a 5-minute ride, and Otsu to Kyoto is only about 10 minutes.
  • Med日跑者's approach: stay in central Kyoto the night before and take the JR to Otsu in the morning. Far more choice of rooms in Kyoto.

逐項數字，刻意不加總。兩片給的租車價差很大，因為車種與配件不同。

Per item, deliberately not totalled. The two guides quote very different rental prices because the bikes and accessories differ.

14 · 還欠什麼

14 · What's still missing

上面的內容不論答案如何都成立。以下會改變細節。

Everything above holds regardless. These change the specifics.

  1. 日期。四月（櫻花）還是十月（紅葉）——兩者都好，但四月的海津大崎櫻花只有很短的窗口。
  2. 幾多天。兩片都用三天。若同行有人想輕鬆些，四天或只繞北湖 150 公里都是實在的選項。
  3. 誰去。這條路線比濟州更適合獨自或兩人成行——沿湖有 JR 平行，隨時可以退出（前提是有輪行袋）。若帶家人，京都／大津作基地、家人玩京都會更合理。
  4. 自己帶車還是租。兩片都是租。租的最大好處是可以異地還車。
  5. Med日跑者的 Day 2、Day 3 影片。vault 目前只有 Day 1。若之後補上，長濱與彥根一段會有更多第一手細節。
  1. Dates. April (blossom) or October (autumn colour) — both good, but the Kaizu Osaki cherry window is very short.
  2. How many days. Both guides used three. If anyone wants it easier, four days or the 150 km north-lake loop are real options.
  3. Who's coming. This suits solo or a pair better than Jeju did — the JR runs alongside the lake, so you can bail at any point, provided you have the rinko bag. With family, basing in Kyoto or Otsu and letting them do Kyoto makes more sense.
  4. Rent or bring a bike. Both guides rented. The big advantage of renting here is offsite return.
  5. Med日跑者's Day 2 and Day 3. The vault only has Day 1. If those land, the Nagahama and Hikone legs will gain first-hand detail.
